MR-DIO-1

I/O model with MODBUS RTU output.
Module MR-DIO-1 serves as an external expansion device digital inputs or outputs programmable logic controllers PLC or other devices in which data exchange is via RS-485 port in accordance to the MODBUS RTU protocol.

Functioning
Module MR-DIO-1 has six universal contacts. Each of the contacts depending on how the connection can be a digital input or output. Digital input, treated as a "dry contact", is realized by closing the circuit the input to the "minus" power supply module. Digital output, described as "open collector", is realized by closing the circuit the output to the "plus" of power supply module
The module has a recording of output function in non-volatile local memory. After each power-output module will revert to a saved state.
Reading status of contacts, setting their status and communication parameters is realized through the RS-485 port using MODBUS RTU communication protocol.
