The TT TTRR/TRT temperature signal transmitter manual explains operation panel, wiring, parameter settings, alarm functions, analog output, and Modbus…
The TT TTRR/TRT is a temperature signal transmitter that converts temperature measurements into configurable analog current or voltage signals and provides alarm and relay functions. It supports Modbus RTU communication over RS‑485.
This manual describes the device’s front panel, key functions, meter parameter settings, alarm configuration, analog output options, and detailed communication settings, including baud rate, address, and Modbus command formats. This manual is written in Chinese.
