EGE Elektronik Sensor Amplifiers for Ex Productseries SZAb 400 EX-WR115

Description

The EGE Elektronik SZAb 400 EX-WR115 is the authoritative solution for facilities operating on 115V AC power that require robust monitoring of sensors in volatile zones. In hazardous locations, electrical energy must be strictly controlled to prevent the ignition of gases, vapors, or dust. The SZAb 400 EX-WR115 accomplishes this through Intrinsic Safety, limiting the energy sent to the field sensor to levels that are incapable of causing a spark. The “WR115” designation indicates that this model is specifically engineered for 115V AC industrial power grids. It is designed for mounting on a standard 35mm DIN-rail within a safe area (non-hazardous zone), serving as the secure connection point for EGE flow or level probes situated within the “Ex” zone.

Features

Potential-Free Relay Output: A high-capacity change-over (SPDT) contact for universal signal interfacing with PLCs or alarms.
Line Integrity Monitoring: Built-in diagnostics to detect and signal cable interruptions or short circuits.
Adjustable Time Delay: 0 to 25-second switch-off delay to prevent “relay chatter” in unstable flow conditions.

Applications

North American Industrial Sites: Utilizing 115V AC control power for hazardous area flow monitoring.
Chemical Storage Facilities: Monitoring tank levels or venting airflow where flammable vapors are present.
Food Processing: Safe airflow monitoring in dust-hazardous zones (flour, sugar, starch silos).
Oil & Gas Refining: Providing safety interlocks for secondary flow lines in volatile processing areas.
