Product Description

Siemens 7PV0732-1AV20 Multifunction Electronic Timer – 15 Functions, 1C/O, 20–240V AC/DC

The Siemens 7PV0732-1AV20 is a multifunction electronic timer with digital display, offering 15 selectable timing functions, 1 changeover contact (1C/O), a 20–240 V AC/DC universal control supply, and a compact 17.5 mm module width. Siemens' 7PV0 timing-relay documentation identifies this exact article as the 15-function multifunction timer with digital display.

The timer is designed for industrial control applications where different time-delay, pulse, interval, cyclic and latching functions may be required from a single compact timing relay.

Siemens 7PV0732-1AV20 Multifunction Timer

The 7PV0732-1AV20 belongs to the Siemens 7PV0 timing relay family. Unlike a dedicated on-delay timer, it provides multiple selectable operating functions, allowing one device to be configured for different control-timing requirements. Siemens describes the 7PV0 range as suitable for delayed switching applications in control, starting and protection circuits.

The exact article uses a digital LCD display, a 17.5 mm module, and 35 mm DIN rail mounting, making it suitable for compact control panels.

15 Selectable Timing Functions

The 7PV0732-1AV20 provides 15 timing functions. The documented functions are:

• ON delay (A)

• Interval (B)

• Asymmetrical cyclic OFF first (C)

• Asymmetrical cyclic ON first (D)

• Cyclic equal OFF first (E)

• Cyclic equal ON first (F)

• Pulse output (H)

• Delay on break (J)

• Delay on make/break (K)

• Interval after break (L)

• Single shot (P)

• Retriggerable single shot (Q)

• Latching relay (R)

• Delay on break with totalise (T)

• Interval with totalise (U)

These functions make the timer suitable for a wide range of industrial timing requirements without needing a separate timer for each operating mode.

Universal 20–240 V AC/DC Supply

The timer operates from a broad 20–240 V AC/DC control supply range. This universal supply range makes the 7PV0732-1AV20 suitable for control systems using different AC or DC auxiliary-voltage levels.

The specified rated frequency is 50/60 Hz for the AC supply.

1 Changeover Contact

The timer provides 1 changeover output contact (1C/O).

The output can be used as a timed switching interface in compatible control circuits. Siemens' technical data specifies:

• AC-15: 3 A at 250 V AC

• AC-12: 5 A at 250 V AC

• Maximum thermal current (Ith): 5 A

The actual connected load must be selected according to the applicable utilization category and relay-output rating.

Four Time Ranges / 8 Selectable Timing Ranges

Your supplied product title mentions 4 time ranges, but Siemens' technical documentation for 7PV0732-1AV20 identifies 8 selectable timing ranges. The documented ranges are:

• 0.1–1 s

• 1–10 s

• 6–60 s

• 1–10 min

• 6–60 min

• 1–10 h

• 2–20 h

• The overall setting capability extends up to 999 h depending on the selected range/function.

For the SB Smart listing, 8 time ranges is the technically supported specification from the available Siemens documentation, rather than 4.

Digital Display

The 7PV0732-1AV20 uses a digital LCD display. The display provides a convenient interface for setting and viewing timing values. The Siemens documentation identifies the 15-function model as the version with LCD display, while the simpler models use LED indication.

This digital interface is particularly useful when different timing values need to be configured accurately.

Timing Accuracy

The 15-function version has the following documented timing performance:

• Setting accuracy: ±0.5% of set time

• Repeat accuracy: ±0.1%

• Recovery time: less than 100 ms

These specifications support precise and repeatable timing in compatible control applications.

Compact 17.5 mm Module

The 7PV0732-1AV20 has a compact 17.5 mm module width, helping save valuable space inside electrical control panels. Siemens documentation specifies the overall dimensions as approximately:

17.5 × 60 × 90 mm

The compact design makes it suitable where several control devices need to be installed within limited DIN rail space.

DIN Rail Mounting

The timer is designed for 35 mm DIN rail mounting. Siemens documentation lists DIN rail mounting as the standard installation method for the 7PV0 timing-relay range.

This makes the device suitable for:

• Control cabinets

• Electrical panels

• Machine-control panels

• Industrial automation assemblies

• Switchboards

Screw Terminal Connections

The timer uses screw terminal connections. Siemens documentation specifies M3 screw terminals and a screw-tightening torque of 0.6 Nm.

For solid conductors, the specified conductor cross-sections include:

• 1 × 0.75–2.5 mm²

• 2 × 0.5–1.5 mm²

For fine-stranded conductors with end sleeves:

• 2 × 0.5–1.5 mm²

• 1 × 0.5–2.5 mm²

LED and LCD Status Indication

The 7PV0 range uses visual status indication, while the 15-function 7PV0732-1AV20 includes an LCD display for timing information. Siemens' technical data indicates red LED for Power ON and green LED for Relay ON along with the LCD display.

This provides useful visual feedback during commissioning and maintenance.

Industrial Timing Applications

The 7PV0732-1AV20 can be considered for applications such as:

• Industrial machines

• Automation control panels

• Motor start control

• Conveyor sequence delay

• Lighting circuits

• HVAC systems

• Automatic door and roller-shutter systems

• Traffic-light signalling systems

• Pumping and irrigation systems

• Building control systems

The selected timer function should match the actual control sequence.

ON-Delay and Interval Applications

For standard applications, the timer can provide ON-delay or interval functionality.

For more advanced requirements, the same device supports cyclic, pulse, single-shot, latching and totalising functions. This makes it useful when multiple timing requirements are present within a project.

Cyclic Timing Functions

The timer supports both symmetrical and asymmetrical cyclic operation, including:

• Cyclic equal OFF first

• Cyclic equal ON first

• Asymmetrical cyclic OFF first

• Asymmetrical cyclic ON first

These modes can be used in compatible repetitive switching processes such as sequencing, flashing and periodic operation.

Pulse and Single-Shot Functions

The device also supports:

• Pulse output

• Single shot

• Retriggerable single shot

These functions are useful for applications requiring a timed pulse rather than a continuously held output.

Latching and Totalising Functions

The 15-function version includes:

• Latching relay

• Delay on break with totalise

• Interval with totalise

These extended functions provide additional control possibilities for applications requiring accumulated timing or latching behaviour.

Electrical Performance

Siemens documentation lists the following technical characteristics for the 15-function timer:

• Rated insulation voltage (Ui): 300 V AC

• Impulse test voltage (Uimp): 2.5 kV

• Rated frequency: 50/60 Hz

• Power consumption: approximately 4 VA

• Degree of protection: IP20

• Pollution degree: 3 for product

These specifications are relevant when integrating the timer into an electrical control panel.

Environmental Conditions

The documented operating and storage conditions are:

• Operating temperature: 0 to 50°C

• Storage temperature: −20 to +70°C

• Relative humidity: 25% to 75%

The device should be installed in an environment compatible with these operating limits.

Endurance

Siemens' technical data specifies:

• Mechanical endurance: approximately 10 million operating cycles

• Electrical endurance: approximately 0.1 million cycles at AC-15, 3 A, 250 V AC and 900 operations/hour

Actual service life depends on the switching load and operating conditions.

IEC Compliance

The Siemens 7PV0 timing-relay range is designed in accordance with IEC 61812-1. The documentation also specifies EMC immunity testing for industrial environments according to IEC 61812-1.

The product documentation identifies CE certification.

The technical values above are based primarily on the published Siemens 7PV0 technical documentation.
