The 4DI-M is an innovative device that provides a simple and inexpensive extension of the input lines of popular PLCs.

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

The module has 4 digital inputs with counter option. Inputs are isolated from logic using optocouplers. Each channel can be individually configured in one of several modes (counting pulses, counting time, encoder).

The module has a fast non-volatile memory type FRAM that stores the values of the counters and the values of the counters captured. Thanks to this, even after power failure, these values are stored and can be used after the power is restored.

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 useful for diagnostic purposes and helping to find faults.

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