Time relay 10-function PCS-516AC 0.1s–576h 2A 1NO 85–265V AC/DC TRIAC DIN rail

The PCS-516AC is a compact 10-function time relay designed for DIN-rail mounting in electrical panels. It provides a wide timing range from 0.1 seconds up to 576 hours and accepts a universal supply voltage of 85–265V AC or DC. The device features a single normally open (1NO) output with a 2 A rating and a TRIAC switching element, making it suitable for a variety of timed switching tasks such as lighting control, delay and pulse operations, and basic automation sequences.

Advantages

The time relay combines a broad timing range and multiple selectable operating modes in a small DIN-rail housing, allowing flexible integration into control cabinets. Its universal 85–265V AC/DC supply simplifies installation across different systems without additional power converters. The TRIAC output offers reliable switching for resistive and certain inductive loads up to 2 A, and the single normally open contact layout keeps wiring straightforward for common timed-control applications.

Suitable for

• Lighting control and stairwell/off-delay systems
• Delay-on, delay-off and pulse timing in control panels
• Basic automation sequences and time-dependent switching
• Timing tasks in HVAC, pump control and small motor protection (within output ratings)
• Retrofit and new installations in residential and light-commercial electrical panels

Key specifications

• Timing functions: 10 selectable modes covering delay, pulse and cyclical operations
• Timing range: 0.1 seconds to 576 hours
• Supply voltage: 85–265V AC/DC (universal input)
• Output: single normally open contact implemented with a TRIAC switching element
• Rated output current: 2 A

How to use

Install the relay on a standard DIN rail inside the electrical cabinet and connect the supply to the universal input terminals according to the supplied wiring diagram. Configure the desired timing function and time range using the front-panel controls or selectors provided on the module. Wire the load to the normally open output terminal, observing the 2 A TRIAC output rating and recommended load types. Verify correct operation by applying supply voltage and testing the selected timing mode before full integration into the control circuit.

Usage recommendations

Use the relay within its specified voltage and output current limits. For inductive or high inrush loads, consider adding appropriate protective components or choose a switching device sized for higher currents. Ensure proper panel grounding and follow local electrical codes during installation. Regularly inspect connections and settings as part of preventive maintenance.
