Time Relay FF PCR-515 DUO single-function 24/230V 10A

The FF Time Relay PCR-515 DUO single-function 24/230V 10A is a compact electromechanical timing device designed to provide reliable timed on/off control in automation installations. With a dual-voltage supply (24 V and 230 V) and a 10 A switching capacity, this single-function time relay is suitable for basic timing tasks where a single programmable delay or pulse is required. Its straightforward configuration and robust switching contact make it applicable for lighting control, motor start delays, HVAC sequencing and other simple timing operations in both residential and light industrial environments.

Advantages

The relay's dual-voltage input increases installation flexibility by accepting either low-voltage 24 V or standard mains 230 V without additional converters. A single-function design simplifies programming and reduces the chance of incorrect mode selection, while the 10 A switching capacity supports a variety of loads such as lighting circuits and small motors. The compact form factor allows mounting in control panels or DIN-rail enclosures, saving space in distribution boards.

Suitable for

• Timed lighting control for stairwells, corridors, or outdoor lighting
• Start-delay for small motors and pumps
• Sequencing in HVAC systems for fan or damper control
• Simple timing functions in automation panels and residential installations

Key specifications

• Supply voltage: selectable 24 V or 230 V
• Function: single-function time relay (one timing operation)
• Switching capacity: 10 A resistive/inductive loads
• Contact type: single changeover or appropriate switching contact for timed control
• Mounting: DIN-rail or panel-compatible compact housing

How to use

Install the relay in a suitable control enclosure or on a DIN rail according to local electrical regulations and wiring diagrams. Select the correct supply voltage (24 V or 230 V) before powering the device. Connect the load to the relay contact terminals and set the required timing parameter following the device's front-panel or dial controls as provided by the manufacturer. After configuration, apply power and verify operation by triggering the control input or manual test to ensure the relay switches the load at the intended intervals.

Usage recommendations

Use the relay within its rated switching capacity and verify load type (inductive or resistive) when connecting motors or coils. Provide appropriate short-circuit and overload protection in the supply circuit. In systems sensitive to timing accuracy, allow for commissioning checks and periodic functional tests to confirm consistent operation.
