Hoyles S312N-8B-PSU 8 x S312N relay modules in an enclosure with a 5A 12vdc PSU. This enclosure includes 8 of our S312N interface relays along with a 5A 12vdc power supply which is capable of battery chaging. All of the relays operate independently of each other but have power pre-connected for convenience. The S312N devices accept a variety of input conditions (Voltage, Logic, Closed Circuit and Open Circuit) for interfacing various signals via voltage free DPCO contacts.

Hoyles S312P-B-PSU S312P 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. PNP Transistorised interface relay. With the two B inputs this is configured as a NOR gate i.e. When neither B is present the relay will switch.

Hoyles Transistorised double pole timer relay module. Transistor driven timer relay module. This device accepts a variety of input conditions (Voltage, Logic, Closed Circuit and Open Circuit) for interfacing various signals via voltage DPCO contacts. The action of the device 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. Self adhesive backed for easy mounting. Four mounting holes provided for more permanent fixing. Screw terminals for easy connection.

Hoyles Transistorised double pole relay module PNP version. General purpose transistor driven interface relay but with inverse operation to our NPN version. In other words when voltage is applied to the input the relay de-energises rather than energising. This device accepts a variety of input conditions (Voltage, Logic, Closed Circuit and Open Circuit) for interfacing various signals via voltage free DPCO contacts.
