Product Description

Siemens 7PV0712-1AD20 Electronic On-Delay Timer – 1C/O, 230V AC, 17.5 mm

The Siemens 7PV0712-1AD20 is a 7PV0 electronic ON-delay timer designed for industrial control and timing applications. It provides a 1 changeover contact (1C/O), operates on 230 V AC, and has a compact 17.5 mm module width for space-efficient control-panel installation. Siemens' official operating instructions identify this exact article as the 7PV0 712 ON-delay timer.

Siemens 7PV0712-1AD20 Electronic Timer

The 7PV0712-1AD20 is a dedicated ON-delay electronic timer within the Siemens 7PV0 timing-relay family. Unlike the 7PV0723 multifunction model, this device is intended specifically for ON-delay timing, making it suitable where the output needs to change state after a defined delay following application of the control signal.

The product is designed for compact industrial control panels and can be used in applications where a controlled delay is required before energizing a downstream relay, contactor or other compatible control device.

230 V AC Control Supply

The exact 7PV0712-1AD20 is designed for a 230 V AC control supply. Siemens documentation lists the supply-voltage tolerance as −15% to +10%.

This makes it suitable for control circuits using a 230 V AC auxiliary supply.

The control voltage must match the specified relay article before installation.

ON-Delay Function

The primary function of the 7PV0712-1AD20 is ON-delay timing.

When the control signal is applied, the timer waits for the selected preset time before changing the output relay state. This allows equipment or circuits to start in a controlled sequence.

Typical applications include:

• Sequential motor control

• Contactor delay

• Pump starting delay

• Conveyor sequencing

• Alarm delay

• Lighting delay

• Machine-control circuits

• Process-control timing

1 Changeover Contact

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

The changeover output can be used to switch a compatible control circuit after the configured delay.

The output specifications include 3 A at 250 V AC under AC-15, 5 A at 250 V AC under AC-12, and a maximum thermal current of 5 A according to the 7PV0 technical documentation.

The actual load must be selected according to the relevant utilization category and circuit conditions.

17.5 mm Compact Module

The 7PV0712-1AD20 has a compact 17.5 mm module width, making it suitable for control panels where DIN rail space is limited.

The compact format allows the timer to be installed alongside other control components such as:

• Contactors

• Control relays

• Circuit breakers

• Terminal blocks

• Interface devices

The 7PV0 design is intended for space-efficient panel integration.

DIN Rail Mounting

The timer is designed for 35 mm DIN rail mounting or compatible plug-in socket installation. This makes it suitable for industrial electrical panels and control cabinets.

DIN rail mounting supports:

• Organized panel installation

• Simple replacement

• Standardized mounting

• Easy maintenance

• Efficient control-panel layout

Multiple Time Ranges

The supplied product description mentions 10 time ranges, but Siemens' official operating instructions for 7PV0712-1AD20 identify 6 selectable time ranges:

• 0.1–1 second

• 1–10 seconds

• 0.1–1 minute

• 1–10 minutes

• 0.1–1 hour

• 0.3–3 hours

Each selected range provides 10 adjustable positions, which may be the reason some commercial listings describe the product as having “10 time ranges.” For technically accurate SB Smart content, it is better to state 6 selectable time ranges with 10 setting positions.

Adjustable Timing

The front-panel setting allows the required delay to be selected within the chosen time range.

The 7PV0712-1AD20 provides 10 setting positions within each range. For example, the 1–10 second range allows settings from 1 to 10 seconds, while the 0.3–3 hour range provides 10 corresponding settings from 0.3 to 3 hours.

This makes the timer practical for applications requiring different delay durations without changing the device.

Visual Status Indication

The Siemens 7PV0 timer provides front-panel status indication for operation and relay status. This helps technicians monitor the device during commissioning, maintenance and troubleshooting.

Visual status indication can make it easier to confirm whether the timer has auxiliary power and whether its output relay has operated.

Screw Terminal Connection

The timer uses conventional screw-terminal connections for integration into the control circuit. The 7PV0 documentation provides terminal wiring and connection information for the 7PV0712 series.

This arrangement is suitable for standard electrical-panel wiring.

Industrial Control Applications

The 7PV0712-1AD20 can be considered for compatible applications such as:

• Industrial control panels

• Machine-control systems

• Motor-control circuits

• Conveyor systems

• Pumping systems

• Lighting control

• Alarm circuits

• HVAC control

• Process-control panels

• Sequence-control applications

Motor and Contactor Delay

An ON-delay timer can be used where a contactor or motor starter must operate after a defined waiting period.

For example, in a machine sequence, a downstream device can be energized only after the timer completes its preset delay.

This can help coordinate different stages of a control sequence.

Conveyor and Machine Sequencing

In conveyor and machinery applications, the timer can provide a delay between two control actions.

This is useful where equipment requires a short waiting period before a subsequent motor, actuator or signalling circuit is energized.

Alarm and Signalling Applications

The timer can also be used where an alarm or signalling circuit should be activated only after a defined delay.

This can help prevent immediate operation during normal startup conditions where a temporary state is expected.

Difference from Multifunction Timer 7PV0723-1AZ20

The 7PV0712-1AD20 is a dedicated ON-delay timer, while the 7PV0723-1AZ20 provides 10 selectable timing functions. Siemens' official documentation clearly differentiates these two product types.

Therefore:

7PV0712-1AD20 → ON-delay timer

7PV0723-1AZ20 → Multifunction timer, 10 functions

Difference from Digital Multifunction Timer 7PV0732-1AV20

The 7PV0732-1AV20 is Siemens' more advanced multifunction timer with 15 functions and digital display, while 7PV0712-1AD20 is a dedicated ON-delay model.

The 7PV0712 is therefore more suitable when only ON-delay operation is required.

Replacement and Maintenance

The 7PV0712-1AD20 can be used as a replacement where the existing installation requires a 230 V AC ON-delay timer with 1C/O output.

Before ordering, verify:
