Product details

Product details

The TS-TC series thermocouple signal isolator accepts the thermocouple signal from the field, and outputs the standard current/voltage signal to the control room, PLC, display instrument and DCS, etc.

Through the miniUSB interface to connect the PC host computer to the input signal division number, range range, alarm output value; Output range, type, etc. RS485 communication function (need to be customized)

The product needs independent power supply, using DIN35mm standard guide rail independent installation mode (optional bus power supply function); The input, output and power supply are isolated from each other.

Wiring diagram

Wiring diagram

Note:

1. When the thermocouple is input, the compensation wire should be directly connected to the input terminal, and the conductor of other materials should not be connected in the middle, otherwise the measurement error will be caused.

2, the bus power supply and RS485 output function is optional, if necessary, please specify and purchase the bus power supply module when ordering. The TS-TC5XX has no 485 output function.
