B&R Industrial Automation 8BAC0120.001-2 IO Module

8BAC0120.001-2 is an EnDat 2.2 encoder interface plug‑in module for the B&R ACOPOSmulti drive system. Designed to be installed in ACOPOSmulti, it provides a high‑speed EnDat 2.2 feedback interface for servomotors and external axes, with encoder connections via a 9‑pin DSUB module‑side connector and UP/DN status indicators. The module communicates with encoders over a synchronous RS‑485 serial link up to 6.25 Mbit/s and supports encoder monitoring, with a maximum encoder cable length of 100 meters (depending on cable construction). The encoder power supply delivered by the module is typ. 12.5 V with a maximum load of 350 mA, while the module itself consumes about 500 mW plus 19 V times encoder current. It occupies ACOPOSmulti plug‑in slots (noted as Slots 1 and 2 in BR documentation) and carries the B&R ID code 0xB0BF. Certifications include CE and UKCA, with UL/cULus listing noted for the broader power‑conversion equipment category. This plug‑in module is part of the 8BAC0120 series and is intended for use with ACOPOSmulti modules to enable precise EnDat 2.2 encoder feedback for B&R servo systems and external axes.
