Optomux and Pamux Brain Boards: Opto 22 brain boards, like SNAP brains, create a truly distributed and scalable I/O system. Used with a host computer, these boards provide local intelligence for an efficient, reliable distributed system. Both Optomux® and Pamux® brain boards are available. Ethernet Optomux Brain Boards The E1 and the E2 are Ethernet versions of Opto 22’s Optomux family of brain boards, designed to migrate existing Optomux installations to faster networks. The E1 and E2 offer higher performance and more communication options while preserving existing I/O racks, modules and field wiring. Designed as drop-in replacements for Opto 22’s serial-based B1 and B2, the E1 and E2 can connect to standard 10/100 Mbps Ethernet networks while also including support for serial Optomux-based networks. The E1 upgrades the B1 brain board for digital I/O systems, while the E2 upgrades the B2 for analog I/O. Each brain board communicates with a host computer and performs control functions for each I/O point. Features:

Drop-In Replacement for Existing B1 and B2 Brain Boards on an Optomux Serial Network

Dual Network Connectivity: RS-422/485 Serial and 10/100 Mbps Ethernet

Optomux, Modbus/TCP and OptoMMP Protocol Support

Provides an upgrade path to Opto 22 PAC Project Software for Control, HMI and OPC Server Serial Optomux Brain Boards The B1 and the B2 are the original serial Optomux brain boards. B1s and B2s communicate with a host computer via an RS-422/485 serial link using twisted-pair cable. B1 and B2 Optomux units can be configured for either multidrop or repeat mode operation. The B1 brain board controls digital I/O modules. It mounts on Opto 22 I/O racks with Standard (G1), G4, Quad Pak, or SNAP I/O modules. The B2 brain board controls G1 analog I/O modules. Pamux Brain Boards Opto 22’s Pamux system provides low-cost, high-speed distributed control of both digital and analog I/O. A Pamux system can span up to 500 feet and support up to 32 stations with a total of up to 512 I/O points. Pamux brain boards include the B4 (32-channel digital), the B5 (16-channel digital) and the B6 (16-channel analog).

The B4 is an addressable digital brain board that controls up to 32 input or output points. The B4 is designed for use with the G4PB32H mounting rack for single-point digital I/O, or the PB32HQ mounting rack for quad pak I/O.

The B5 controls up to 16 digital input or output points and works with a variety of Opto 22 I/O mounting racks, including racks that accept single-point or quad pak digital I/O as well as racks with integrated digital I/O circuitry.

The B6 controls up to 16 analog input or output points. It is compatible with several mounting racks, including the PB4AH (four points of analog I/O), PB8AH (eight points), and PB16AH (16 points). TERM1 and TERM2 termination cards provide termination for the Pamux bus. Features:
