Overview
The Mechanical Relay with Socket is the interposing relay between a PIERRE controller and a mains load. The coil runs at 12 V DC, matching the controller output directly, and the single changeover contact switches up to 16 A at 250 V AC.
It plugs into a socket on 35 mm DIN rail, so the relay can be replaced without disturbing field wiring, and commons across a row of relays can be bridged with the PIERRE busbar range rather than wired terminal to terminal.
Where the circuit switches frequently, use the Solid State Relay with Socket instead, which has no contacts to wear.
Key features
- Contact rated 16 A @ 250 V AC
- Coil 12 V DC — drives directly from a controller output
- Single changeover contact (SPDT)
- DIN rail

1. Product Description
DIN-rail relay module that lets a PIERRE controller switch mains or high-current loads. The coil is driven from a 12 V DC signal output pin on the controller, with a second wire back to the controller's GND to close the circuit. Coil polarity is not critical — A1 and A2 can be interchanged.
The contact side is a potential-free changeover, fully isolated from the 12 V control side:
- 11 — COM, the common pole; the switched line feeds in here
- 12 — NC, connected to 11 when the coil is off
- 14 — NO, connected to 11 when the coil is on

3. Connections Diagram
Wire the relay as follows:
- A1 / A2 – connect the relay coil supply here. Apply the rated coil voltage across A1 and A2 to activate the relay, these are the connections from PIERRE controllers output pin and GND.
- 11 – COM – common contact.
- 12 – NC – normally closed contact. 11 and 12 are connected when the relay coil is OFF.
- 14 – NO – normally open contact. 11 and 14 are connected when the relay coil is ON.
