Time Relay FF PCS-516DC

FF PCS-516DC is a time relay designed for control and automation tasks that require timed switching. The device provides programmable delay functions to control switching circuits in electrical installations and control panels. It is intended for use in industrial and building automation systems where reliable, repeatable time-based control of loads and signal circuits is necessary.

Advantages

The time relay offers precise and adjustable time-delay functions with stable performance across typical industrial voltage ranges. Its compact form factor is suitable for DIN-rail mounting in control cabinets, allowing straightforward integration into existing panels. The device provides clearly defined timing modes and consistent switching behaviour for repeatable automation sequences.

Suitable for

• Timed switching of lighting circuits in commercial or industrial buildings
• Sequence control of motors, valves and pumps in process automation
• Delay functions for alarm and signalling systems
• Interlocking and staged start-up of electrical loads

Key specifications

• Function: programmable time delay relay for switching circuits
• Timing modes: multiple selectable delay functions for on-delay, off-delay and pulse timing
• Time range: adjustable over short and extended intervals (user-selectable)
• Control voltage: DC supply compatible with common industrial DC ranges
• Output contacts: electromechanical relay contacts for switching loads and signal circuits
• Mounting: DIN-rail compatible housing for straightforward panel installation
• Operating environment: designed for standard industrial and building automation conditions

How to use

Install the relay on a DIN rail inside the control cabinet, following electrical safety rules and local regulations. Connect the DC control supply and the input/output circuits according to the wiring diagram supplied with the unit. Select the desired timing mode and set the delay value using the front panel adjustments or configuration interface. Verify operation by testing the relay through a complete timing cycle before commissioning into regular service.

Usage recommendations

Use appropriate protective devices such as fuses or circuit breakers on supply and load circuits, and ensure correct contact ratings for the expected load. Perform periodic functional checks and visual inspections for secure mounting and proper electrical connections to maintain reliable time-based control in automation applications.
