Multifunction Timer Relay FF PCS-516 DUO 24/230V AC/DC, 8A Output

FF PCS-516 DUO is a multifunction timer relay designed for a wide range of control and automation applications. The device accepts both 24 V and 230 V supply (AC or DC) and provides an 8 A output for switching loads. Configurable timing modes include delayed ON/OFF, cyclic, and pulse functions, enabling flexible integration into HVAC, lighting, motor control and industrial automation panels.

Advantages

The relay combines dual-voltage supply compatibility with a single compact housing, reducing inventory complexity and installation effort. A broad set of timing functions and adjustable intervals allow precise control over switching sequences without additional controllers. The 8 A output supports direct switching of many resistive and inductive loads, while the clear front-panel markings simplify connection and setting. Robust design ensures stable operation in typical control panel environments.

Suitable for

• HVAC system control and sequencing
• Lighting control and timed switching
• Motor start/stop and soft-start applications
• Industrial automation panels and process control
• Pumps, fans and other cyclic or intermittent loads

Key specifications

• Supply voltage: compatible with 24 V and 230 V (AC or DC)
• Output current capacity: 8 A
• Operating modes: delayed ON/OFF, cyclic operation, pulse and other timing functions
• Adjustable time ranges: multiple timing intervals configurable via front controls
• Mounting: DIN-rail compatible compact housing for electrical panels
• Connection: screw terminals for power and load wiring

How to use

Install the relay on a standard DIN rail inside the control panel and connect the supply voltage according to the rated input (24 V or 230 V, AC/DC) using the marked screw terminals. Make the load connections to the output terminal rated for 8 A, observing polarity and wiring standards for inductive loads if applicable. Select the required timing function and adjust the time range and interval using the front-panel controls or selector. Verify correct operation by applying supply power and testing the configured cycles before connecting critical equipment.

Usage recommendations

For reliable long-term operation, ensure the relay is mounted in a ventilated panel away from excessive heat and moisture. Use appropriate suppression (snubber or RC circuit) when switching inductive loads to extend contact life. Confirm that connected loads do not exceed the 8 A rating and follow standard wiring practices and local regulations for installation and earthing.
