The G4PB4 I/O mounting rack compactly accommodates up to four G4 I/O modules in applications where only a few I/O points are needed. Insert and remove modules easily and quickly without disturbing field wiring. Modules are secured to the mounting rack with a threaded captive hold-down screw. Barrier strips with screw terminals provide the field, control, and mounting rack power connections.
