B&R 8AC120.60-1 Analog Input Module

8AC120.60-1 is an EnDat 2.1 encoder interface plug‑in module designed for ACOPOS servo drives, offering a dedicated encoder interface and real‑time encoder monitoring in slots 2, 3 or 4. It supports EnDat 2.1 data and can be used to evaluate simple incremental encoders with sinusoidal input signals. The module provides 15‑pin DSUB module‑side connection, differential sine/cosine inputs with differential voltage 0.5 to 1.25 Vss and a common‑mode range up to ±7 V, plus 120 Ω termination. Serial communications run over RS485 at 625 kbaud, and the reported resolution is 16384 multiplied by the number of encoder lines; encoder monitoring is enabled and the maximum encoder cable length is 50 m. Power consumption depends on the connected encoder and configuration, ranging from roughly 2.3 W to 3.1 W. The device is CE and UKCA certified and UL listed (cULus E225616). Operating conditions are 5 to 40 °C (55 °C max), storage from −25 to 55 °C, and 5 to 85% relative humidity (noncondensing). The data sheet and product page identify material number 8AC120.60-1 and describe it as an EnDat 2.1 encoder interface for installation in ACOPOS drives with encoder monitoring and the ability to evaluate incremental encoders with sinusoidal input signals.
