Powered by GS/AI

The 201A-AU-OT is a three-phase voltage monitor for 190-480 V ac, 50/60 Hz motors, packaged with an OT08PC octal socket for DIN-rail or surface mounting. It features auto-ranging voltage sensing, adjustable trip delay (1-30 seconds), adjustable restart delay (manual or 1-500 seconds), and a 2-8% adjustable voltage unbalance trip point. It includes a single LED for fault diagnostics, a 10 A @ 240 V ac general-purpose relay output, and operates across -40° to 70 °C. The device complies with UL 508 and IEC 61000-4-X standards for surge, ESD, and transient immunity. Dimensions are 44.45 mm H × 60.325 mm W × 104.775 mm D with socket.
