The Phoenix Contact Varioface cabling system for PLCs has now been extended to include passive interface terminal blocks.
The Phoenix Contact Varioface cabling system for PLCs has now been extended to include passive interface terminal blocks.
Just 6.2mm wide, the new PLC-VT passive terminals are identical in size with the existing active interface terminals in the Varioface range, allowing eight interface channels, comprising any combination of passive, relay and solid-state relay terminals, to be accommodated in just 50mm of mounting space on a standard DIN rail.
In use, the new terminals are simply plugged into a PLC Relay adapter, which connects them to a Varioface ready-terminated plug-in cable.
The remote end of the cable plugs into the PLC input or output card via an easy-to-fit faceplate which can be supplied in versions to suit most popular types of PLC.
This system greatly reduces I/O wiring complexity and cost, while maximising flexibility.
Phoenix Contact PLC-VT passive interface terminals are available in versions to suit both PLC Relay Universal and PLC Relay Actuator adapters.
All types allow for the termination of two extra circuits, in addition to the main circuit, and all can optionally be supplied with a built-in LED indicator.
PLC-VT terminals are fully compatible with a wide range of standard Phoenix Contact accessories, including test plugs, marking products, and links.
The terminals feature screw-clamp connectors for the field wiring, and can accept flexible cables from 0.2 to 2.5mm2, or solid cables from 0.2 to 4mm2.
