eTR 101 Modbus
Room Temperature Control Unit
Temperature controller
The Room Temperature Control Unit eTR 101 Modbus measures the room temperature and displays the current value. The target temperature can be changed using the + and - touch buttons. The eTR 101 Modbus is a Modbus slave with RS485 interface and RTU protocol. Modbus master, e.g. PC, SPS or MC, can read the measured values and other settings with ""Function 04h (read input registers)"" or with ""Function 06H (write single register)"" and ""Function 10H (write multiple registers)"" adjust, for example, the display of the setpoint or the basic setpoint shifts.
Models:
N° 30180 eTR 101 Modbus, signal white RAL 9003
N° 30181 eTR 101 Modbus, jet black RAL 9005
- Temperature measurements.
- Display of the current temperature or the setpoint and the basic setpoint shifts
- 2 touch keys (+/-) for changing the target temperature or the basic setpoint shifts
