MB-PT100: 1-channel PT100 probe input module, RS485 communication with Modbus RTU protocol

The MB-PT-100 transducer is designed to measure temperature using an external PT-100 temperature sensor and to transmit data via the RS-485 port using the MODBUS RTU protocol.

The unit continuously measures temperature using an external sensor. The reading of recorded temperatures, setting of all measurement parameters, communication, and data transmission occur via the RS-485 port using the MODBUS RTU communication protocol. Power-on is indicated by a green LED U. Valid data exchange between the unit and the second device is indicated by a yellow LED Tx. The unit works with a three-wire PT-100 temperature sensor. The probe is sold separately.
