DI40

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

Key Features

  • Safety features for high running safety
  • Galv. isolated CAN interface acc. to ISO 11898
  • Easy access to all interfaces
  • Own intelligence for complex CAN networks
  • All clamps pluggable and lockable
  • Signal delay of less than 400 μs
  • Galv. isolated inputs
  • Compact aluminium housing with IP20 and integrated top hat rail mounting

Description

Housing and interfaces
The module has a compact aluminium housing and offers the possibility of 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 DI40 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.
