Additional Control Ports

Digital I/O (digital input/output) ports (IPL EXP 200, IPL EXP RIO8)
To allow the IPL EXP to monitor devices to trigger events, connect switches, sensors, LEDs, relays, or similar
items to these ports. Connect physical switches, sensors, LEDs, relays, or similar items to these ports, which
can be configured 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 set up using Global
Configurator. By default these ports are set as digital inputs with pull-up disabled.

Digital input — To allow the EXP to monitor external devices that do not use RS-232 communication, connect
a switch, motion sensor, moisture sensor, tally feedback output, button pad, or a similar item to a digital I/O port
and configure it for digital input. When configured as a digital input, the port is set to measure two states: high and
low. The port accepts 0 to 25.3 VDC input.
Threshold voltages are not adjustable. The thresholds are:
2.0 VDC — port on, logic low
•
• 2.8 VDC — port off, logic high
There is also an internal, selectable, pull-up resistor connected to +5 VDC, which you can use if the connected
device does not provide its own power.

Digital I/O (digital input/output)
Con gure each port 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.
