Description
This device is an electronic switching unit designed to enable low voltage signal control of high power circuits while incorporating tamper detection and recovery mechanisms. It is engineered for applications requiring secure, fail safe operation, such as access control systems, industrial equipment protection, or critical infrastructure monitoring, where any unauthorised interference must be detected and addressed immediately.
The unit includes an integrated tamper switch, which may be actuated by events such as removal of a key switch. When triggered, the device enters a lockout state that disables relay control via the trigger switch.
Normal operation can only be restored by pressing the reset switch (S1), ensuring that any tamper event is acknowledged before functionality is re enabled. This design provides an additional level of protection in applications where prevention of unauthorised interference is essential.
