Which initial state do the MR-DO(A)4 outputs have after a reset or communication loss?
Is defined by the value in register 1 (see software manual).
MR-F-DO4 Modbus RTU
Description
The Modbus module with 4 digital outputs was developed for decentralized switching tasks. It is suitable for switching electrical components, such as motors, contactors, lamps, louvers, etc. In this case it is necessary to protect the relay contacts by appropriate load-dependent measures. The module is provided with a manual control for manually switching the relays. The outputs can be switched by means of standard registers via a Modbus master. Module address, bit rate and parity are set with 2 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 spring clamp terminal blocks (push-in)
