Product Description
The ACM12 is a serial communication module supporting RS-422 and RS-485, designed for reliable long-distance data exchange in industrial control systems. It provides configurable parity, character length, and stop-bit settings for compatibility with diverse devices. Half-duplex operation with ASCII or binary support makes it ideal for connecting PLCs, drives, sensors, and remote I/O over distances up to 1,200 meters.

FAQ
Q: Can the ACM12 be installed with the ACF11 module?
A: No. The ACM12 cannot share the same nest with the ACF11 but is compatible with ACM11.
Q: What cabling is recommended for the full 1,200 m range?
A: Use 3-pair shielded industrial communication cable or the dedicated AKB161 cable to ensure signal integrity and EMI protection over long distances.
