MR-F-SM4i Modbus RTU
Description
The MR-F-SM4i module is a Modbus RTU energy meter designed for use in building and industrial applications. Current, voltage, active power, reactive power, apparent power, and other relevant energy parameters can be measured for up to 3 phases plus neutral (L1, L2, L3, N) using current transformers with 1 A/5 A secondary current. The values can be retrieved via a Modbus master. The module address, baud rate, and parity are set via two rotary switches on the front side of the module or via software. Suitable for decentralized mounting on a TH35 mounting rail according to IEC 60715 in electrical distribution cabinets.
- Connection with spring clamp terminal blocks (push-in)
