Digital I/O Module with 128 TTL Channels

The IO207 I/O module is a digital input and output module with Simulink® driver blocks.

The module features 128 TTL channels arranged in 16x 8-bit ports. The direction of the I/O lines is software programmable for each port.

Each port is built up using a TTL bus transceiver and each line is protected against ESD and overvoltage. Software-selectable pull-up/pull-down resistors are also available on all the I/O lines.

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

Mean time between failures (MTBF)* 617,000 hours
MTBF (Mean Time Between Failure) - MTBF values shown are based on calculation according to MIL-HDBK-217F and MIL-HDBK-217F Notice 2; Environment: GB 20°C. The MTBF calculation is based on component FIT rates provided by the component suppliers. If FIT rates are not available, MIL-HDBK-217F and MIL-HDBK-217F Notice 2 formulas are used for the FIT rate calculation.
