VDB8904 DIN Rail Mounted 8 x RS232 Port Terminal Board for SBS Octal IP

 

  • Connects plants signals to VME64x modules
  • DIN rail mounted
  • Constructed from high impact plastic

 

Product Description

The VDB8904 is an assembly that offers a simple solution to the problem of connecting plant wiring to Hytec VME64x transition modules. It is designed to mount on standard DIN EN 50035 or OMEGA-DIN 50022-50045 DIN rail. The VDB8904 utilises a glass fibre PCB to connect the Mini delta 50way SCSI II type connector to eight 9-way Cannon D-type sockets. The arrangement of the connections is designed for use with the Greenspring Octal RS232 port Industry Pack card and a straight -through transition board.

The housing is made of high impact plastic.
