Hoyles Transistorised single pole relay module

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 Boxed Quad Double Pole Relay Module. Four 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 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.

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.
