G4 I/O family
The G4PB4 I/O mounting rack compactly accommodates up to four G4 digital I/O modules in applications where only a few I/O points are needed.
Single-channel G4 I/O gives you maximum flexibility. All modules on the rack must use the same logic voltage (5 VDC, 15 VDC, or 24 VDC). 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. For easier wiring, use the G4STRAPB.
