Short description:

Digital 24 V module with 40 inputs for use in CAN networks.

Housing and interfaces
The compact housing is made of aluminum. It contains a top hat rail mount and a front cover with all interfaces for better overview in the control cabinet. The technician will note the convenience while working at the bus cabling. The Remote-IO series uses 3-wire cabling for direct connection to sensors and actors, supplying them with power. In order to reduce the danger of false-wire harnessing the 3-wire clamps are coloured. If you wish to see the status of each channel, we can deliver the modules with LED-clamps. All inputs and outputs can be monitored with the help of LEDs at the clamps. In addition to that, you can configure the baud rate and module address with HEX-switches at the front cover - easy and comfortable.

Signal processing
Besides its inputs and outputs the DI40 offers a powerful micro-controller that handles data acquisition of sensors, control of actors and the processing of any CAN-data. An important safety function is the DI40‘s guarding capability which is fully integrated into the IO for network surveillance. Furthermore, there is a relay contact (changeover) as an additional safety measure. If there is an absence of guarding by the master registered, the module immediately goes into STOP-mode.

Power supply
The DI40 needs a power supply with 24 V. Due to the polarity reversal protection the user is in no danger of damaging the module by reversed power connection. Short surge peaks are also eliminated by an EMI wiring for the control section.
