TB10 and TB9 - Digital Output Connections
The TB10 and TB9 connectors each provide 16 digital (common ground) output connections designed to
drive externally-mounted relays or other indicating circuits. Each output can sink up to 100 mA of
current. External circuitry (relays, indicators, etc.) must be powered from an external power supply of the
same voltage used to power the I/O Control Module (12 to 24 V dc). The ground (or dc common)
terminals of the external power supply must be tied to TB4 (-).

• Active Low State - sinks 100 mA (max) to GND.
• Active High State - output floats high to source
voltage.
