Hoyles S312N-2B-PSU S312N relay module in a steel enclosure with a 2A 12vdc PSU

Hoyles Boxed Tri Double Pole Relay Module. Three completely separate double pole change over relays on a single PCB mounted in a standard white plastic single gang enclosure complete with front and back acting tamper switch.

Hoyles S312N-20 Pack of 20 S312N relay modules. A bulk 20pack of our S312N transistorised relay module. Transister driven DPCO Interface relay module . This device accepts a variety of input conditions (Voltage, Logic, Closed Circuit and Open Circuit) for interfacing various signals via voltage free DPCO contacts.

Hoyles S312N-8 8 x transistorised double pole relay modules on a single PCB. This single PCB contains 8 of our transister driven DPCO Interface relay modules. All modules operate independently but have power pre connected on the PCB for convenience. The modules accept a variety of input conditions (Voltage, Logic, Closed Circuit and Open Circuit) for interfacing various signals via voltage free DPCO contacts.

Hoyles Mains rated relay kit. This kit is designed for switching a 240vac mains load of up to 5A operated by a 12vdc or 24vdc input from an intruder for fire alarm system depending on version. The relay coil is rated at 35mA. Two white plastic single gang enclosures are provided for segregation of the alarm system and the mains connections. The first enclosure is tampered and contains a relay with single pole change over contacts rated 5A at 240vac or 12/24vdc. The relay coil requires 12vdc or 24vdc, depending on version, to operate. An LED is also provided which illuminates when the relay is energised. The tamper switch is normally closed and opens when the face plate is removed from the wall. The second enclosure is purely a junction box which provides a replication of the SPCO contacts. An earth terminal is also provided for convenient termination of an in coming mains cable. As the enclosures are all plastic, no earth connection is required. A loop of cable is provided within the kit to connect the two enclosures together.
