From analog signal to industry standard

The Pt100 Modbus converter acquires the measuring signal of a Pt100 temperature sensor and makes the measured value available for interrogation via Modbus RTU (RS485). Due to the simple address assignment from 1...99 by code switches, up to 99 temperature sensors can be quickly integrated into a bus. Like the other Lambrecht Modbus RTU sensors, the Pt100 Modbus converter also has autoconfiguration registers (mapping). Thus it can be automatically recognized by the data logger met[LOG] and created for the measurement with just one push of a button.
