VEICHI VH Right Expansion Modules
Up to 16 I/O modules per rack on a 100 Mbps backplane
The I/O that turns a VH controller into a full rack. Digital, analog, temperature and PT modules clip onto the right-hand D-BUS, up to sixteen per controller. Removable terminals mean a failed module swaps out without touching the field wiring.
