G4 I/O family
The G4PB4R output mounting rack compactly accommodates up to four G4 output modules and features channel-to-channel isolation between all field and control circuits.
I/O modules on this rack can have varied logic voltage. You can mix 5 VDC, 15 VDC, and 24 VDC logic modules on the rack. This rack cannot use dry contact output modules.
This rack supports negative-true or positive-true logic on a point-by-point basis. Each point can handle control signals differently.
Barrier strips with screw terminals provide the field, control, and mounting rack power connections. For easier wiring, use the G4STRAPB.
