B&R 8AC123.60-1 ACOPOS Incremental and SSI Encoder Interface Module
Product Overview
The B&R 8AC123.60-1 is an ACOPOS plug-in module for connecting incremental encoders and SSI absolute encoders to compatible ACOPOS servo drives. It provides differential signal transmission, encoder monitoring and selectable encoder supply voltage.
The module supports incremental square-wave signals as well as SSI absolute-position data. It is particularly useful when an ACOPOS axis requires external position feedback, machine position measurement or connection to an SSI-based absolute measuring system.
Main Features
- Incremental and SSI absolute encoder interface
- One electrically isolated encoder input
- Selectable 5 VDC or 15 VDC encoder supply
- 350 mA supply capacity at either voltage selection
- Short-circuit and overload-protected encoder supply
- 32-bit incremental encoder counter
- Incremental input frequency up to 200 kHz
- SSI word width up to 31 bits
- Maximum encoder cable length of 50 m

Maintenance and Replacement Notes
Confirm whether the installed feedback device is incremental or SSI, and verify supply voltage, SSI coding, word width, signal frequency, DSUB pin assignment and encoder cable. Incorrect encoder supply selection may damage the feedback device.
