  • 8 Channels 10 bit analog input
  • 8 digital I/O
  • PWM Output
  • 32 Bit pulse counter input
  • RS232 interface 9600-115.2K

This Integrity Instruments data acquisition module uses RS232 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.

The A/D channels are unipolar, with an input range of 0 to 10vdc.

RS232 connection is via a DB9 connector. The digital I/O and the analog channels are accessed via 15 pin connectors. Module power is applied through a 2.5mm connector.
