DS-TP Universal signal isolator

· 1 in 1 out, 1 in 2 out. General purpose signal (RTD/TC/mV/mA) input. Configurable settings. LCD display (optional) or LED backlight indication. 0/4~20mA output. Terminal supply or DIN rail power supply is available.

· The DS-TP Universal Signal Isolator is used to connect field RTDs, thermocouples, millivolts, transmitters (distribution) or current sources. After isolation, it is converted to a standard current signal output to a control system or other instrument.

· 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.
· LCD display (optional) or LED backlight indication.
· This product requires a separate DC power supply. Voltage-type magnetic isolation between power supply-input-output.
