Overview
The Opto 22 PB32HQ is a high-density mounting rack designed for the Opto 22 Quad Pak I/O family. This 8-module rack houses discrete digital input and output modules in a compact form factor, making it ideal for applications requiring flexible I/O configuration in space-constrained control systems. The PB32HQ supports both serial (Pamux protocol) and Ethernet (OptoMMP protocol) connectivity through optional brain board modules.
Key Features
- Supports 8 Quad Pak I/O modules (32 total discrete points in 4-point increments)
- 50-pin screw terminal connector for secure wiring
- Compatible with B4 brain (Pamux serial protocol) or G4EB2 brain (Ethernet/OptoMMP protocol)
- Dense, vertical mounting footprint with header connector
- Enables mix-and-match digital I/O module selection
