What are the dimensions of the AL1371?
The module measures 100 x 80 x 40 mm (W x H x D) and weighs approximately 200 g.
Can I mount the AL1371 on a DIN rail?
Yes, the device is designed for 35 mm DIN rail mounting per EN 60715.
What is the operating temperature range?
The AL1371 operates reliably from -25°C to +70°C. Storage range is -40°C to +85°C.
How many inputs and outputs does the AL1371 have?
It provides 4 inputs and 4 outputs for connecting sensors and actuators.
Is the AL1371 compatible with older AS-i versions?
Yes, it supports AS-i version 3.0 and is backward compatible with version 2.1.
What should I do if the device LED indicates a fault?
Check the AS-i cable connections and power supply. The LED codes are: green = normal, red = fault, flashing = address conflict. Refer to the manual for details.
Can I replace the connector myself?
Yes, the M12 connector is replaceable. Use only IFM approved connectors to maintain IP rating. Ensure power is off before replacement.
