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.

issue commands, send e-mail), once con gured.
• Power LEDs or other devices that accept a TTL
signal.

Figure 11. Digital I/O Port Wiring Examples
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.
