WAGO 750-424 2-channel digital input module for the WAGO I/O System 750 designed for intruder detection and alarm loop monitoring using current-loop inputs.
£60.41
The WAGO 750-424 is a specialised 2-channel digital input module for the WAGO I/O System 750, designed for monitoring alarm contacts and security circuits within industrial and building automation systems. The module operates using a current loop monitoring principle, allowing controllers to detect both normal signal states and wiring faults commonly used in intruder detection systems. :contentReference
The module detects the status of connected contacts and transmits this information to a WAGO fieldbus coupler or programmable controller. By analysing resistance values within the circuit, the module can identify normal operation, alarm states or wiring faults, making it suitable for security monitoring applications integrated with automation systems. :contentReference
Designed for reliable industrial operation, the module provides electrical isolation between the field and system levels and uses WAGO CAGE CLAMP® spring pressure connection technology for vibration-resistant wiring and fast installation. Its compact DIN rail form factor allows seamless integration into distributed control cabinets. :contentReference
Digital input modules used in alarm monitoring systems allow controllers to detect changes in contact states and wiring integrity. By monitoring resistance values within a current loop, security systems can distinguish between normal operation, triggered alarms and wiring faults.
The WAGO 750 Series modular I/O platform allows alarm monitoring functions to be integrated into larger building automation or industrial control systems. This provides a scalable architecture where security signals and automation data can be processed within the same distributed control network.
