100% Original New MTL2442B 4/20mA ISOLATING DRIVER With Best Discount Price In Ex-Stock
The MTL2442B isolates and passes on a 4/20mA signal from a safearea controller to drive a hazardous-area load such as a current-topressure (I/P) converter, a position actuator, or an electrically-driven valve, etc. Input and output circuits float independently to ensure compatibility with all types of drive instrumentation and permit the use of earthed or poorly insulated loads. In conjunction with an MTL2441B repeater power supply, the unit can be used to pass measurement or control signals through a hazardous area between two safe areas. The MTL2442B supersedes the MTL2442 but is designed for 240/120V ac supplies only. For a 24V dc powered model refer to the MTL5045.
