What is the difference between the MR-DIO4/2 and MR-DIO4/2S?
The MR-DIO4/2 has 2 changeover contacts (switch-on current 80 A, less than 20 ms) and the MR-DIO4/2S has 2 NO contacts (switch-on current 160 A, less than 20 ms).
MR-DIO4/2S Modbus RTU
Description
The Modbus module with 4 digital inputs and 2 relay outputs with manual control was developed for decentralized switching tasks. It is suitable for accommodating, for example, light switches and window contacts in a room, switching 2 light strips or controlling louvers. It can also be used to control 2 motorized fire dampers. In this case it is necessary to protect the relay contacts by appropriate load-dependent measures. The inputs can be used as contact or voltage inputs. The inputs and outputs can be switched and scanned 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.
