HALswitch R8 Relay/Digital Interface Board


Please note: Our annual vacation close-down takes place from 03.06.2026 until 26.06.2026.
There will be no support and no shipping during this time.

PLEASE NOTE: the HALswitch is "end of life" and should not be used for new designs any more.
For existing systems, please ensure to have an appropriate stock!

The HALswitch R8 board is an easy and quick solution to integrate a scanner controller card into a machine. It makes use of 24V and even 250V directly.
This digital interface board is designed in a way to allow fast installation: connection to the used scanner controller card requires a 1:1 cable only. After applying 24V power to the board, it is fully functional and all the digital inputs and outputs can be used with the higher voltages that appear within a machine typically.
The HALswitch R8 board provides the following features:

  • 8 digital inputs and 8 digital outputs, fully galvanically insulated
  • a second HALswitch board can be connected to offer additional 2/8 digital inputs and additional 2/8 digital outputs (dependent on used controller card)
  • inputs can be operated with 12..24V directly
  • outputs can switch up to 250VAC/30VDC and 7A permanent/12A peak
  • all outputs act on relays directly with a normally opened and a normally closed contact each
  • can be connected to DigiI/O extension board of E1701A / E1701C / E1701D controller card via simple 1:1 cable
  • can be connected to digital interface of E1803D scanner controller card via simple 1:1 cable
  • can be connected to Intelli-IO extension board of E1803D scanner controller card via simple 1:1 cable
  • can be connected to EXTENSION interface of SCAPS™ USC-2™ or USC-3™ control card via simple 1:1 cable
  • can be connected to EXTENSION1 interface of Scanlab™ RTC5™ or RTC6™ control card via simple 1:1 cable
  • can be connected to GPIO header of a Raspberry Pi™ single-board computer via simple 1:1 cable
  • compatible with E1803base for easy mechanical installation

HALswitch R8 mounting example:

  • E1803base (in vertical direction and upper mounting position) used to clamp the whole stack onto a DIN/C45 rail
  • HALswitch R8 on top allowing to thread the 24V and 250V wires from lower side

Attention: mounting of the HALswitch board has to be done via non-metallic and non-conductive screws/bolts in order to not to break the galvanic insulation the HALswitch board provides!
