Banner Engineering ES-FA-9AA Safety Relay Module

Banner Engineering's ES-FA-9AA Safety Relay Module is a 24 V AC/DC safety relay designed for E-stop, rope-pull, and interlock safety circuits, delivering three normally open outputs rated 6 A each and a single safe input channel configurable for dual-channel dry contact or single-channel operation. The unit supports a safety input reset path and uses a removable terminal block in a compact 84 x 22.5 x 118 mm enclosure with IP20 and NEMA 1 protection for panel mounting. Key electrical specs include a dual-channel dry-contact input of 10–20 mA at 12 V DC, a reset input of 20 mA at 12 V DC (dry contact only), and a single-channel input of 40–100 mA at 24 V AC/DC ±10%; it draws 2 W / 2 VA of power and uses AgNi contacts with gold-plating (5 microns). Safety performance is rated Cat. 4, PL e, SIL 3, and the device offers a typical response time of 25 ms with a recovery time of 250 ms, making it suitable for fast-stop safety applications. With a mechanical life of 20 million operations and an input/output configuration of 3 NO outputs, the ES-FA-9AA is a compact, robust choice for emergency-stop and interlock safety networks.
