The 8I8O is an innovative device that provides simple and inexpensive expansion of input and output lines in popular PLCs.

The module communicates with all commercially available PLCs, devices that support the popular MODBUS MASTER protocol.

The device has 8 digital inputs with configurable counter and 8 digital outputs. Inputs and outputs are isolated from logic using optocouplers. Each channel can be individually configured in one of several modes (counting pulses, counting time, encoder).

This module is connected to the RS485 bus via two wire twisted pair. Communication is made using the MODBUS RTU or MODBUS ASCII protocol. The use of a 32-bit ARM core processor provides fast data processing and fast communication. The transmission speed is configurable from 2400 to 115200.

The module is designed for mounting on DIN rail according to DIN EN 5002.

The module is equipped with a set of LEDs used to indicate the status of inputs and outputs useful for diagnostic purposes and for helping to find errors.

Configuration of the module is done via USB with a dedicated computer program. It is also possible to change parameters using the MODBUS protocol.

SLIM modules can be easily connected to each other via the Quick Connector. Just supply the module and RS485 power to the first module. With the MOD-QC tape, both values will be passed to the next modules.

Available accessories:

  • Connecting tape: MOD-QC
  • Programming cable: mini USB
