The RE2.F4C.AC230.L0 gives you four full changeover contacts from one plug-in relay, with a built-in LED and mechanical test button so you can see relay state and force-test the circuit without breaking any wiring. Running on 230VAC, it's a straightforward isolation relay for control circuits already switching at mains voltage. It's priced well below premium-brand equivalents and held in UK stock for fast dispatch.
Includes:
- LED indication
- Transparent housing for easy visual inspection
- Manual test button and mechanical indicator
- Compatible with standard relay sockets
Requires relay base: RS2.N4CO.14V.S0 (sold separately)
Technical Details
Frequently Asked Questions
Why use a miniature relay instead of switching the load directly?
It lets you control a larger load with a small control current, often at a lower voltage — useful for electrical isolation (protecting PLC outputs), latching circuits needing multiple contact sets, or driving auxiliary functions like indication from spare poles.
What does the LED and test button do?
The LED shows relay coil status at a glance, and the manual test button lets you force-operate the relay for fault-finding without disturbing field wiring — the transparent housing also aids visual inspection.
Do I need a separate base to mount this?
Yes — this relay requires the RS2.N4CO.14V.S0 relay base, sold separately, for DIN rail mounting.
What does 4PCO mean?
Four independent changeover (pole) contacts, giving flexibility for redundancy, expansion, or driving multiple separate circuits from one relay.
Industry Applications
- PLC output isolation — protecting sensitive control electronics from larger switched loads
- Control panel building — latching circuits, auxiliary signalling, and redundant switching
- Maintenance & fault-finding — quick field replacement and visual diagnosis via transparent housing
