XSA-TP universal signal barrier

·  1 in 1 out, 1 in 2 out. General purpose signal (RTD/TC/mV/mA), intrinsically safe input. Configurable settings. 0/4~20mA output. Support HART communication. Terminal supply or DIN rail power supply is available. 

·   The XSA-TP Universal Signal Barrier is used to connect thermal resistance, thermocouples, millivolts, transmitters (distribution) or current sources in hazardous areas on site. After isolation, it is converted to a standard current signal output to the safety zone control system or other instruments.

·   Switch power distribution, current, RTD, thermocouple, and millivolt signal input according to different wiring methods. The input signal type or range can be configured via software.

·   Load adaptive electrical energy saving technology, load adaptive wide range output up to 0~800Ω.

·   Support for HART communication (optional).

·   This product requires a separate DC power supply. Voltage-type magnetic isolation between power supply-input-output.
