EGE Elektronik Sensor Amplifiers for Ex Productseries SZAb 400 EX-WR230

Description

The EGE Elektronik SZAb 400 EX-WR230 is the authoritative solution for processing data from flow and level sensors installed in volatile environments. In such areas, any electrical spark can lead to a catastrophe this amplifier prevents such risks by limiting the energy transmitted to the sensor via Intrinsic Safety. The “WR230” designation indicates that this specific model is optimized for a wide-range 230V AC power supply, making it ideal for integration into standard industrial electrical panels without the need for additional DC power converters. It is designed to be mounted on a 35mm DIN-rail in a safe area (non-hazardous zone), acting as the bridge to the sensors located in the “hot” zone.
