Overview of all interfaces
32 digital inputs

Connection technology
Using the 3-wire connection technology, all sensors can be connected directly to the module. The phoenix clamps used ensure a simple and extremely robust connection, which makes the IDI32 very resistant and process safe. Each IO block of the device is galvanically isolated and is sup­plied with power separately. Thus, different vol­tages can be applied to one module for the operation of emergency stop circuits such as safety doors.

CAN interface
Two RJ45 sockets for the CAN interfaces are provided on the module, allowing easy con­nec­tion to other modules via Ethernet patch cables. In this way, decentralized use of the module is also possible.

LEDs and switches
All inputs are indicated by an LED above the clamp. In addition, both the baud rate and the module address can be set and read at any time using HEX switches.

Signal processing
In addition to the inputs, the IDI32 has a power­ful micro­con­trol­ler that handles the ac­qui­si­tion of the sensors, the control of the act­u­ators and the CAN protocol.
