Description
Housing and interfaces
The module has a compact aluminium housing and offers the possibility for top hat rail mounting. The interfaces are quickly and conveniently available on the front panel. Using the 3-wire connection technology, all sensors can be connected directly to the module. The danger of incorrect wiring is greatly reduced by the color coding of the potentials, even for less experienced users. Various clamp strips are available, which are optionally equipped with LEDs. All inputs are indicated by an LED on the clamp. In addition, both the baud rate and the module address can be set and read at any time using hex switches.
CAN interface
The integrated CAN interface in accordance with CANopen (DS 301 and 401) allows flexible use at different points and positions in the production process. It is designed according to ISO 11898.
Signal processing
In addition to the inputs, our digital IO has a powerful microcontroller that handles the acquisition of the sensors and the CAN protocol. Furthermore, security mechanisms such as guarding are fully integrated in the remote IO.
Power supply
The DO32 is supplied with 24 V. The integrated reverse polarity protection prevents possible destruction of the module if the supply voltage is incorrectly applied. The control section is additionally protected against short overvoltage peaks by an EMC circuit on the supply voltage.
