The RE2.U2C.DC024.S0 is a compact PCB-mount relay with two changeover contacts, coil-driven at 24VDC — a natural fit for PLC output isolation on space-constrained control boards. Its 8-pin PCB footprint suits panel builds where the larger 14-pin plug-in relays wouldn't fit. It's priced well below premium-brand equivalents and held in UK stock for fast dispatch.
Requires relay base: RS2.M2CO.08V.S0 (sold separately)
Technical Details
Frequently Asked Questions
What's the difference between this and the RE2.F4C series relays?
This U2C relay has 2 changeover contacts on a compact PCB-mount 8-pin package, versus the F4C series' 4 contacts on a larger 14-pin plug-in package.
Does 24VDC mean the switched contacts are also limited to 24V?
No — the 24VDC is the coil (control) voltage only. The contacts can switch up to 250V AC, letting a low-voltage PLC output control a mains-voltage load.
Do I need a separate base to mount this?
Yes — this relay requires the RS2.M2CO.08V.S0 relay base, sold separately.
What does 2PCO mean?
Two independent changeover (pole) contacts, letting you wire two separate circuits or a redundant pair from one relay.
