Sink Input(Please confirm module model support):
The module provides 24V DC power,and the external device is internally grounded(compatible with PNP sensors).
Note:The IC610MDL129A typically uses a source input;please refer to the manual for specific specifications.
2.2 Electrical Characteristics
Input Voltage Range:
24V DC(-15%to+20%),i.e.,19.2V to 28.8V,to accommodate voltage fluctuations.
Input Current:
Typical:3mA/channel(at 24V DC);
Maximum:7mA/channel(to ensure compatibility with low-power sensors).
ON Level Threshold:
≥15V DC(signal voltage above this value is recognized as a”1″).
OFF Level Threshold:
≤5V DC(signal voltage below this value is recognized as a”0″).Response Time:≤2ms(from signal change to controller reading the change).
2.3 Isolation and Protection
Channel-to-Channel Isolation:
None(shared power between two groups requires external isolated power supplies or careful wiring).
Power Isolation:
Module power is isolated from the backplane bus to prevent interference.
Overvoltage Protection:
Integrated TVS diodes on the input ports suppress transient voltage spikes(such as lightning strikes and induced electromotive force).
