6.1 Control of IP Power 9211: Read IO
Source mode (Voltage input):
IN1-IN4 contacts are active signal sensor. If the voltage difference between the two contacts in one set
within 0V~3V, 9212 shows ON. It the voltage difference within 4V~24V, 9212 shows OFF. So user can
detect the change of equipment. Such as smoke detector, light detector and gas detector.
Sink mode (Resistance Input):
IN5-IN8 contacts are short circuit sensor. If the resistance between the two contacts in one set within
0Ω~200Ω, 9212 shows ON. If the resistance within 500Ω~
∞, 9212 shows OFF. So user can detect the
movement of equipment through the magnetic reed switch or other kind of reactive sensors.
NOTE
:
1. The data in this figure is the average measure value. To ensure the correct detection, we suggest
user set the voltage lower than 200Ω when it shows ON and higher than 500Ω when it shows OFF.
2. When measure the resistance of web contacts, the maximum voltage is 5V and the maximum
currency is no more than 10

Click the refresh button and user will see the similar figure like this. It represents the state of the four
sets of input signals (there may be some delay, it up to user network).
