Additional Control Ports

Flex I/O ports (see
H
the IPCP Pro Series control processor to monitor devices to trigger events, connect
switches, sensors, LEDs, relays, or similar items to these ports. Flex I/O ports can be
configured as analog inputs, or as digital inputs or outputs with or without +5 VDC
pull-up. These ports can trigger events or functions (such as triggering relays, issuing
commands, or sending an e-mail) that have been configured using GC. By default these
ports are set as digital inputs with pull-up disabled.

Con gure each port as an analog input or as a digital input or output with or without +5 VDC pull-up.
Use these ports to:
• Monitor or trigger events and functions (toggle relays, issue commands, send e-mail), once con gured.
• Power LEDs or other devices that accept a TTL signal.

Analog input — When a Flex I/O port is configured as an analog input, the port can
measure 0 to 25.3 VDC with 12-bit accuracy (±6 mV). A DC level is indicated by a count
from 0-4096 (≈ 6 mV per count).
Example application, analog input without pull-up: measuring voltage output
•
of a temperature sensor
In this example you set the port for analog input then connect a temperature sensor
to an external voltage source and to the flex I/O port. You must know the output
voltage of the sensor that corresponds to the sensed temperature in order to set
threshold voltages correctly within Global Configurator software.
