- TC type J, K, T, R, S, E, B, and N or ±100mV input
- 1500V isolation
- 4 to 20mA DC output
The ST133 is a low-cost two-wire transmitter that isolates and 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.
