Multi-IO

Short description:

Powerful 24 V module with 52 in- and outputs for digital and analogue signals.

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. Please bear in mind that those are suited for digital channels only.

CAN interface
The integrated CAN interface is designed in accordance to DS301 and 401 for a flexible use in different places and tasks in the CAN bus network. All Sontheim CAN interfaces comply to ISO 11898.

Signal processing
Besides its inputs and outputs the Multi-IO 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 Multi-IO‘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 Multi-IO 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.
