ModBus module 4 digital inputs and 4 digital outputs

This module has 4 digital inputs and 4 relay outputs.

The digital inputs can be activated or deactivated externally. Each input has associated with it a 32-bit counter and an 8-bit frequency meter.

Description

The characteristics are:

  • 4 self-powered inputs that can be activated by closing a circuit, for example with a limit switch or a sensor with NPN output.
  • Possibility of configuring the inputs to act latcheadas in order not to lose any pulse or edge.
  • Each input can be configured to act as either negative or positive logic.
  • It includes a low-pass filter that eliminates noise and bounces characteristic of switches.
  • 32-bit pulse counter associated with each input whose values are maintained in the absence of current. It can count pulses up to a frequency of 25 Hz. The counter is stored in memory, non-volatile, even in the absence of current.

Digital outputs, implemented as single contact relays. The characteristics are:

  • 4 1-contact relay outputs with switching capacity up to 10A at 250 VAC. The relays are optocoupled from the electronics and have a varistor that protects their contacts.
  • The relays can be activated for a period of time, allowing fast pulses to be given in a controlled manner.

The unit has a non-volatile memory that allows the following parameters to be preprogrammed:

  • State to be taken by the relays when starting the equipment.
  • State to be taken by the relays when the equipment does not detect the presence of the modbus master.
