Hoyles S312P-B-PSU S312P relay module in a steel enclosure with a 2A 12vdc PSU

Hoyles Panel of 20 Double Pole Relay Modules. A panel of 20 of our double pole change over relay modules. Ideal for van stock, individual modules can be snapped off the panel as required. A discounted price compared to buying 20 separate modules.

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.

Hoyles S312T-B-PSU S312T relay module in a steel enclosure with a 2A 12vdc PSU. Interface relay . This device accepts a variety of input conditions (Voltage, Logic, Closed Circuit and Open Circuit) for interfacing various signals via voltage free DPCO contacts. The S312T-B-PSU is similar to the S312N-B-PSU but its action can be delayed by between about 3 and 60 seconds. This can be adjusted with the on board potentiometer. This can be a useful feature where it is necessary to delay one action slightly to allow another.

Hoyles Transistorised double pole relay module NPN version. General purpose transistor driven interface relay. This device accepts a variety of input conditions (Voltage, Logic, Closed Circuit and Open Circuit) for interfacing various signals via voltage free DPCO contacts. Self adhesive backed for easy mounting. Four mounting holes provided for more permanent fixing. Screw terminals for easy connection.
