W0202 Wirelss IO

iSMA

The module is built with a wireless extension of the RS485 bus, wherever the use of a network cable is impossible or unprofitable.

The use of two W0202 allows you to build the so-called wireless “bridge” for the RS485 bus by creating a remote wireless island (or several islands) for the subsequent devices that communicate using Modbus RTU / ASCII – eg. a series of modules MIX or MINI. Module in addition to the RS 485 port and is equipped with wireless 2xSI (input special) and2xDO (digital outputs) allowing the use of it as a lighting controller or I / O module Modbus RTU / ASCII.

W0202 is also equipped with a micro USB port which allows you to configure the device without external power source (the device is fed through the USB port). This solution provides an easy way, using 2 laptops, carry out tests coverage in the existing facility.

Implemented algorithm in the processor allows user to choose one of different modes:

  • Modbus Bridge
  • Modbus Bridge and I/O module (both DO work independent of the state of SI)
  • Modbus Bridge and I/O module with built-in algorithms for light, cooling or heating control.
  • Modbus Bridge and I/O module with present sensors support.
