The BusWorks XT series of Ethernet I/O modules support Modbus TCP/IP, Ethernet/IP, Profinet and i2o peer-to-peer communication protocols. They monitor and/or control up to 16 discrete devices per unit with any mix of inputs and outputs supported.

ST133

Transmitter, Thermocouple Input, Loop-Powered

• TC type J, K, T, R, S, E, B, and N or ±100mV input

• 1500V isolation

• 4 to 20mA DC output

• USB-configured

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. Setup and calibration are fast and easy with a convenient USB connection to your PC and Acromag’s Windows configuration software.
