DESCRIPTION
The G4PB16H and G4PB8H Digital I/O Mounting Racks are designed
for use with G4 digital I/O modules. The G4PB8H accepts up to 8
digital I/O modules, and the G4PB16H accepts 16.
Both racks work with Opto 22’s PBSA, PBSB, and PBSC power supplies.
Logic supply is fused with a 1 A fuse, which, if desired, can be
swapped out for a 5 A fuse (sold separately).
Barrier strips with screw terminals provide the field and mounting
rack power connections. I/O modules are secured to the mounting
rack with a threaded captive hold-down screw. You can insert and
remove modules easily and quickly without disturbing field wiring.
For logic connections, the header connector accommodates the
following devices:
Standard 50-pin cable
Optomux® E1 brain board
Optomux B1 brain board
Pamux® B5 brain board
mistic™ B100 brain board
Digital I/O Carrier Board for Raspberry Pi® (part number
