An interface provides: 1) a connector to plug in a protector, and 2) a way to terminate system wiring. The interface is wired to place the suppression circuits between the equipment to be protected and the field wiring. An interface board with eight connectors for Plug In Protectors is available with three different interfaces for system wiring: 1) The IB8-1 has 32 input and 32 output wire screw clamps for up to 16 gauge wires. 2) The IB8-2 has 32 input and 32 output insulation displacement connections for 22 gauge wires. 3) The IB-3 can supplied with modular phone jacks or plugs or a combination. IB8's have nylon standoffs and mounting hardware. The BPP8WSC is and IB8-1 on a mounting plate supplied with four mounting screws for immediate installation.
The BPE8WSC is a an IB8-1 mounted in a rugged metal box. The cover can be removed without tools using a captive thumbscrew fastener. The cover has compressible foam strips to keep Plug In Protectors from being backed out in high vibration environments. the BPE8WSC is supplied with mounting screws and UV resistant tie wraps for securing system wiring. Two individual connector options are available. The BCP is a printed wiring board mountable connector with two rows of pins. the BCW is a connector with solderable eyelets to connect wires to, and has nylon standoffs and mounting hardware.

How To Choose a Protector Interface

Select an interface based upon the number of lines, the wire termination and the mounting configuration desired. The wire screw clamp has been the most popular because of its flexibility and current rating. For low line counts, the individual connectors are selected when rapid replacement is essential, otherwise, functionally equivalent freestanding portectors are more popular.
