Multifunction Time Relay FF PCS-516 UNI 12–264V AC/DC, 8A Output

FF PCS-516 UNI is a multifunction time relay designed for programmable time control in electrical installations. Supporting a wide universal supply range of 12–264V AC/DC and an output rated up to 8A, this relay provides versatile timing functions for delayed switching, pulse generation and sequence control. The compact module is intended for integration in control panels, industrial machinery, lighting circuits and HVAC equipment where reliable, adjustable time control is required.

Advantages

The relay offers a wide supply voltage range that eliminates the need for multiple models and simplifies inventory. Its multifunctional timing modes allow one device to perform several automation tasks including delay on, delay off, pulse and cyclic operations. With an 8A output rating the device is suitable for directly driving many control loads and for interfacing with contactors and control circuits. The simple front-panel adjustment and clear markings facilitate fast commissioning and maintenance.

Suitable for

• Control panels and machine automation requiring programmable timing
• Lighting circuits with delayed on/off or pulse control
• HVAC systems for staged or timed control of fans and valves
• Sequence control in industrial processes and conveyor systems

Key specifications

• Supply voltage range: 12–264V AC/DC
• Output current rating: up to 8A
• Functionality: multiple timing modes including delay, pulse and cyclic sequences
• User adjustments: front-panel timing and mode selection
• Mounting: modular design for panel or DIN-rail mounting

How to use

Install the relay in a suitable enclosure or DIN rail position and connect supply and load according to the wiring diagram supplied by the manufacturer. Select the required timing mode and set the time value using the front-panel controls. Verify correct operation with test cycles before placing into normal service. Ensure connections are made with power removed and that load ratings do not exceed the 8A output capacity.

Usage recommendations

For reliable operation, use the relay within the specified supply range and avoid continuous loads at the maximum output rating. Where higher switching currents are required, operate the relay via an intermediate contactor. Periodically inspect connections and settings during maintenance to ensure timing accuracy and electrical safety.
