This Integrity Instruments data acquisition module uses RS-232 communication to access 8 digital I/O points. The digital points can be configured as inputs or outputs in any combination. TTL and CMOS compatible for direct control or use our expander board for relay or industry standard I/O modules.

The A/D channels are unipolar, with an input range to 5 vdc.

RS-232 connection is via a DB9 connector. The digital input or output is accessed via a DB25 connector and the analog channels are via DB15 connector. Module power is applied through a 2.5mm connector.
