- Universal thermocouple (8 types) or ±100mV input
- 4-20mA output
- Loop-powered, 7-32V DC
The ST132 is a low-cost two-wire transmitter that converts a millivolt or thermocouple sensor input to a proportional 4-20mA control signal. Power is received from the output loop current. The transmitter performs signal linearization, cold-junction compensation, and lead-break detection functions.
