G4A8R - 

The G4A8R is a high performance analog I/O brick for the Opto 22 family of processors and I/O. It provides intelligent and flexible single point I/O control in a rugged, deadfront, compact package. Customers select the signal type for each of the 8 channels on the brick, in any combination, from the G4 family of isolated analog I/O modules. Up to 16 channels are supported with available expansion options. Each module has channel to channel isolaton and provides 12 bits of resolution. Onboard brick intelligence offers PID loop control, HI/LO limit monitoring, thermocouple linearization, event/reactions, and many other control functions. Event/reactions execute high speed deterministic responses to sophisticated control sequences, alarm monitoring, diagnostics, and host interrupts.

Analog bricks utilize Opto 22's Mistic protocol and high speed serial communications. Programming is accomplished with Opto 22's intuitive multitasking, flowchart-based languages OptoControl or Cyrano. Custom software development is achieved using a host computer and Opto 22's Misticware software driver with the high-level software language of your choice.
