- 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 or use our expander board for relay or industry standard I/O modules.
RS232 connection is via a DB9 connector. The digital input or output is accessed via a DB25 connector. Module power is applied through a 2.5mm connector.
