DIGITAL I/O MODULE
– 8080-0002
This section describes the control and operation of the Xpert Digital I/O module. The Digital I/O
module has eight digital input lines, six of which may be re-programmed as outputs. The two
dedicated input lines can be programmed for normal sensitivity for sensing 0 to 5 volt digital
signals, or high sensitivity for sensing low level signals such as those from an R.M. Young wind
speed sensor.
Features
Eight digital I/O lines, CMOS level inputs
Six bi-directional, two input only
Reconfigurable I/O
Up to eight counters/frequency inputs with programmable alarm
count leading edge, trailing edge or both edges of input pulse.
Up to four quadrature shaft encoder inputs (requires two inputs per sensor) with programmable
alarm
Two switchable threshold inputs compatible with R M Young wind sensor.
Switched sensor power
Industrial temperature range operation –40 to +60
