GPIO and other connectors

GPIO

1 × GPIO (General Purpose Input/Output)

6 pins Phoenix plug, having 4 ports for On/O control, GND

a n d +12V.

You can congure input/output integrations by using pre–

dened behavior. Exposure of states and commands for

external control requires external programming.

Usage information

• A contact closure between the GND and a GPIO port pin is

detected as a low input signal.

• When used for voltage inputs, the GPIO port detects it as:

• Low signal for voltages 0 - 1 VDC

• High signal for voltages 2 - 12 VDC

• When used for outputs, the GPIO port acts as a switch

to GND, and is rated for 500mA @ 48V DC. The +12V pin

provides +12 VDC, and is capable of sourcing up to 500mA.

• The GND connector is a common ground for all pins in the

GPIO port.
