8AC123.60-1

8AC123.60-1 is a B & R Automation module in the 8AC Powerlink Modules series. It provides one encoder input for receiving position or motion feedback. The input accepts square-wave pulse signals at frequencies up to 200 kHz, while 4x evaluation processes four count transitions per signal cycle. Its 32-bit counter operates at up to 800 kHz, supporting a broad counting range and high-speed position tracking. A minimum distance of 0.6 µs is required between signal edges for reliable detection.

The module also supports SSI communication at 200 kbit/s for serial encoder data transfer. SSI words can be up to 31 bits long, and both Gray and binary coding are supported for compatibility with different encoder formats. The module-side interface is a 15-pin female D-sub connection, and the maximum supported cable length is 50 m between the module and connected encoder.

The module uses 5 VDC and 15 VDC supply voltages for its circuitry and connected encoder interface. At 5 VDC, the load capacity is 350 mA, indicating the available current for the attached load. Maximum power consumption is 7.5 W, which provides the upper requirement for power-system sizing.
