G4 I/O family

The G4PB32H I/O mounting rack accommodates up to 32 G4 I/O modules. This I/O rack has a header connector and is designed to be used with one of the following brain boards:

• G4EB2Connects to an Ethernet network and uses the OptoMMP protocol
• B4Connects to a serial network and uses the Pamux protocol

This rack requires 5 VDC logic I/O modules and supports negative-true logic only (zero voltage = ON, and Vcc = OFF).

Barrier strips with screw terminals provide the field connections. A two-position screw terminal for 5 VDC connects to a power supply. For easier wiring, use the G4STRAPB.
