IO203: Digital I/O Module with 64 TTL Channels

Parallel digital I/O module with 64 TTL channels, individually programmable as inputs or outputs

The IO203 I/O module is a dedicated digital I/O module providing a total of 64 TTL channels. The transceivers are TTL and CMOS/TTL compatible and can also be set to be CMOS compliant by on-board jumper.

Each of the 64 channels can be individually programmed as input or output. The 64 channels are also separated into two groups of 32 channels. The module supports a simultaneous update of each group resulting in very low latency.

This I/O module is ideal for closed-loop controls and hardware-in-the-loop (HIL) simulations using MATLAB® and Simulink®.

Digital Inputs/Outputs
