4.2.3 Connecting Output Devices
Up to 8 output devices can be connected to GV-AS210 / 2110 / 2120. Check if your output
device meets the following absolute maximum ratings before connecting it to outputs 1 ~ 8.
Breakdown Voltage
110V AC ~ 250V AC, 30V DC
Continuous Load Current
3A (AC), 3A (DC)
Note:
Absolute Maximum Ratings are those values beyond which damage to GV-
AS210 / 2110 / 2120 circuit board may occur. Continuous operation of GV-AS210 /
2110 / 2120 at the absolute rating level may affect the controller’s reliability.
To connect an output device:
Connect the (+) point on the output device to COM on GV-AS210 / 2110 / 2120, connect the
two (-) points of the output device and the power supply together, and connect the (+) point
on the power supply to the NO or NC of GV-AS210 / 2110 / 2120 based on the state of the
output device.
There are two ways to supply power to the output device:
⚫
Use the power outputs on the GV-AS Controller:
The output device must be a 12V
device. The total power consumption of the output devices and readers connected to
the controller must be under 3A when using the power adapter. If you are using a PoE
adapter for GV-AS2120, the total power consumption must be under 25.5 W.
⚫ Connect an external power supply:
Connect an external power supply if the total
power consumption is exceeded or if the output device requires higher current.
