A 12V DC operating, ABS cased transistor driven relay unit with DPCO (double pole change over) contacts.
The relay can be switched by either applying a standard 12 volt feed to the relay coil or applying a low current (<1mA) positive "trigger" input.
Typical uses include changing the polarity of signals and switching higher currents and voltages (30V DC MAX). It can also be used as an interface between different systems e.g. intruder alarm to access control or fire alarm to access control.
