The module is a 96-channel digital I/O card in MicroPC format. UNIO96-1 accepts TTL-logic level signals.

The main application area of the module - to serve as an interface with opto-module racks MPB-24/TBI-24/TBI-16L (Opto-22, Grayhill) or with isolated I/O terminal boards TBI-xx/xx. Besides, the module can be used to control displays, LED-devices, for frequency measurements, for timing diagrams generation, for code conversion etc.

Opto-module Rack Interface

The main purpose of the UNIO96-1 is to provide an interface with optomodule racks (Opto-22, Grayhill) and with isolated I/O terminal boards TBIxx/xx series (see connection diagram). The card allows to serve 96 modules of any type (analog, digital, input, output).

The serial data transseivers and frequency gage of the UNIO96-1 allow to control 1 input and 1 output Grayhill opto-isolated modules (73G/73L series) simultaneously using no processor resource (interrupt generation is possible).


Digital I/O lines of the UNIO96-1 are terminated with 4 26-pin IDC-type connectors. The TB-26 series terminal boards, MPB-xx series opto-racks, and TBI-xx/xx series isolated terminal boards can be used to connect the external lines to the module. The I/O channels can be pulled to +5 V or GND through 10 kΩ pull-up/pull-down resistors by groups of 24.
