Banner Engineering ES-FA-9AA Photoelectric Sensor

The ES-FA-9AA is a 24 V AC/DC safety relay module from Banner Engineering's ES/GM safety family, designed to monitor emergency-stop devices, rope-pull resets, and interlocks in safety circuits. It provides three normally open outputs rated for up to 6 A and includes a single safety input that can be wired as two NC channels or one NC channel, enabling flexible common wiring schemes. The module is powered from a universal AC/DC supply, features a compact footprint (84 by 22.5 by 118 mm) with a removable terminal block, and is rated IP20 with a maximum operating temperature of 50 C. Key performance specifications include a 25 ms response time and 250 ms recovery time, 2 W power consumption (2 VA), and self-checking circuitry with auto- or manual-reset to help ensure continuous safe operation. Typical applications include integration into E-stop and guard-monitoring systems on production lines, where reliable safety signaling and straightforward installation are critical.
