Industrial I/O Processors (Brains)

About Opto 22 SNAP I/O Family

SNAP analog modules are designed for harsh environments: all are transformer isolated and optically isolated from the field side to the control side. An isolated input module or output module offers channel-to-channel isolation, too. Each SNAP analog module contains 2 to 32 channels of I/O—software configurable by channel—so a small number of modules can handle a wide range of inputs.

SNAP-PAC-R1

SNAP-PAC-R1 programmable automation controller provides control, communication, and I/O processing in a compact, rack-mounted package. A versatile controller, the SNAP-PAC-R1 is:

  • Fully integrated with PAC Project software, SNAP PAC brains, and SNAP I/O modules;
  • Compatible with groov EPIC, either as a SNAP PAC R-series I/O unit to a groov EPIC or to control groov EPIC I/O units (requires PAC Control R10.0a or higher); and
  • Can be used as a remote Ethernet I/O unit to custom control applications running on controllers or PCs.

B3000-B and B3000-B-OMUX

The B3000-B is a mistic serial brain designed as a modern drop-in replacement for the serial B3000 brain. With the same functionality as the B3000, except that it does not support the Optomux protocol. 

  • The B3000-B replaces a B3000 that uses the mistic protocol. This model is compatible with FactoryFloor controllers running OptoControl strategies and SNAP B-series mounting racks. The B3000-B has the same functionality as the B3000 but supports mistic only.
  • The B3000-B-OMUX replaces a B3000 that uses the Optomux protocol. This model is compatible with SNAP B-series mounting racks and contains firmware suited for an Optomux system.

SNAP-B4

A high-performance digital brain used to connect and control up to 32 channels of digital I/O using Opto 22’s SNAP “B Series” I/O mounting racks and the Pamux bus. The SNAP-B4, combined with Opto 22’s AC28 interface card and a host PC, provides the world’s fastest digital I/O.

Capable of communicating over a 50-pin flat ribbon cable (Pamux bus) and can be located up to 500 feet away from the host processor. The Pamux bus has 64 possible addresses. Each group of eight I/O points occupy one address, therefore the Pamux bus can control up to 512 digital and analog I/O points. Each SNAP-B4 brain controls 32 digital I/O points and occupies four consecutive addresses on the Pamux bus.
