Connecting sensors to the I/O card
NOTE: A nominal 12 VDC (non-regulated battery voltage) sensor power is available
on terminal 10 of the input terminal strip. This is a switched power supply and the
warm up time for sensors that require power is configurable using
software. See Sensor power .
Wiring digital inputs
Frequency input
Each I/O card provides up to two frequency inputs for connecting devices such as ultrasonic depth sensors
and/or flow meters. The frequency input terminals available on each I/O card are shown in the diagram
below.
NOTE: If a frequency input is wired a shaft encoder input is not available
After completing the wiring, configure the sensor using (see
Add a new "Frequency" input type
)
Digital or Counter input
Each I/O card provides up to three digital inputs or one counter input for connecting devices such as rainfall
gauges, hours run meters and/or counting pulses. The digital/counter input terminals available on each I/O
card are shown in the diagram below.
NOTE: If a shaft encoder input is wired only a single digital/counter input is
available
