Modbus module with 10 digital inputs

With the MR-DI10 Modbus module, the inputs of M2M Control telecontrol systems can be expanded easily and completely transparently for the application.

The MR-DI10 has 10 digital inputs that can record either potential-free switch states (contacts) or voltages.

The housing is designed for mounting on a top-hat rail in electrical distribution boards; supply voltage and Modbus can be simply looped through via a jumper plug when using several modules.

The module is connected via the RS-485 interface and can be easily configured with the integrated development environment (IDE) as an I/O extension. The I/O extension is fully transparent for the application. The inputs and outputs of the Modbus module can be used in the same way as the ones present in the telecontrol unit. No further configuration tool is required.
