R8
Pin assignment and direction of the digital lines at the 25-pin D-Sub
male connector of the R8 are hard-wired. The control lines (TTL) for
the individual relay output channels OUT 1..OUT8 of an R8 have to
be applied to channels 1-8.

Important notes for using the OR8/R8
•
The OR8 and the R8 are only suitable for extra-low voltages
–
please observe the relevant regulations!
•
An electrically isolated power unit (with CE) must be used for power supply.
•
All accessible pins are electrostatic sensitive devices. Provide for an earthed conductive work place when
installing.
•
Only use non-solvent detergents for cleaning. The product is designed to be maintenance-free.
•
The board must not be used for safety-relevant tasks. With the use of the product, the customer becomes
manufacturer by law and is therefore fully responsible for the proper installation and use of the product. In the
case of improper use and/or unauthorized interference, our warranty ceases and any warranty claim is
excluded.
Do not dispose of the product in the domestic waste or at any waste collection places. It has to be either duly
disposed according to the WEEE directive or can be returned to bmcm at your own expense.
