100mA.
Pin 3
Digital Input
Connect to GND to activate, or leave floating
(or unconnected) to deactivate.
Must not be exposed to
voltages greater than
30V DC.
Pin 4
Transistor
Output
Uses an open-collector NPN transistor with
the emitter connected to the GND pin. If used
with an external relay, a diode must be
connected in parallel with the load for
protection against transient voltages.
Max load = <100mA
Max voltage = 24V DC
(to the transistor)
The I/O terminal pins are numbered from the top down
Connect input/output devices to the camera as follows:
1. Attach the cables for the device securely to the supplied green connector block.
2. Once the cables are connected, push the connector block into the terminal connector (also
green) on the camera.
