ABB PSR60-600-11 Programmable Safety Relay Module

ABB PSR60-600-11 Softstarter, part number 1SFA896112R1100, provides soft-start and soft-stop for AC motors with a mains voltage range of 208–600 VAC and a 24 V AC/DC control supply. Rated for 60 A nominal operating current, it includes a built-in bypass for compact installation and energy savings. The unit offers RUN and TOR signals via a normally open relay output, and ramp profiles are set with three front-panel potentiometers for adjusting start and stop timing. It is designed for use with ABB MMS (manual motor starters) and related mechanical connection kits, enabling easy integration in control panels; typical motor power rating can reach up to around 37 kW at 600 V depending on motor characteristics. The PSR60-600-11 is enclosure-rated IP20, suitable for control cabinet mounting and DIN-rail installation in industrial environments, and is commonly employed to reduce inrush currents, mechanical wear, and electrical stress during motor starting in applications such as manufacturing lines, pumps, and fans.
