The TR202 receives a 4…20mA signal and provides (2X) programmable SPDT relay outputs, (1X) Fail Safe relay as well as a passive 4…20mA signal that can be linked in series with a PLC or can be linked with additional TR202 relays.  Each relay can work independently or together.  In addition, a 3 digit LED indicator provides visual indication between 0…100% of the input signal. The TR202 will work with any type of sensor with a 4…20mA output (i.e. pressures sensors, radar and ultrasonic sensors, temperature sensors, vibration sensors, etc.).
