Product details

HMISAC is a basic element controller from the Harmony SCU range, built around a RISC CPU with a realtime clock and onboard memory (128 MB flash, 128 kB FRAM, 128 MB DRAM). 14 digital inputs (Type 1, sink/source, 24 VDC) plus 2 fast inputs supporting encoder/single-phase/pulse-direction modes at 100 kHz. Panel-mount via a single Ø22 mm nut, accepting panels from 1 to 6 mm thick. Rated IP65 front panel, NEMA 4X, suitable for washdown environments.

Powered from an external 24 VDC supply, draws 15 W total. Communicates via Modbus, Modbus TCP/IP, or CANopen. Compliant with CE, FCC Class A, UL 508, CSA C22.2 No. 213 Class I Division 2, EN 61131-2, IEC 61000-6-2. Pollution degree 2 per IEC 60664, vibration tolerance per IEC 60068-2-6. Relative humidity 5 to 85% non-condensing.
