Which sensors can be connected to the MR-AI8?
Sensors in range from 40 Ohm to 4 MOhm and 0 to 10 V, already stored types (e.g. PT1000) are found in the software manual, a user-defined temperature curve can also be created.
MR-AI8 Modbus RTU
Description
The Modbus module with 8 individually configurable resistance or voltage inputs was developed for decentralized switching tasks. It is suitable for detecting resistances and voltages of, for example, passive and active temperature sensors, electrical vent and mixing valves, valve positions, etc. The inputs can be configured universally by means of standard registers via a Modbus master. Module address, bit rate and parity are set with two rotary switches on the front or by software. Suitable for decentralized mounting on DIN TH35 rail according to IEC 60715 in electrical distribution cabinets.
- Connection with screw type terminal blocks
