Banner Engineering ES-FA-9AA Safety Relay Module

The Banner Engineering ES-FA-9AA Safety Relay Module is a 24 V ac/dc safety relay designed for E-stop, rope pull, and interlock monitoring, delivering three normally open (NO) safety outputs rated at 6 A each and a single safety input configurable as either one dual-channel or one single-channel input with a dry-contact reset option. It features self-checking circuitry with auto or manual reset, a removable terminal block for easy wiring, and a compact 22.5 mm-wide form factor with overall dimensions of 84 x 22.5 x 118 mm (H x W x D). The unit operates from a universal AC/DC supply, carries an IP20 enclosure rating, and supports ambient temperatures up to 50 °C. Input signaling is typically 10–20 mA @ 12 V DC for the safety input and 20 mA @ 12 V DC for the reset input. Recovery time is about 250 ms and the nominal response time is 25 ms, making this module suitable for integration into emergency-stop and guard-monitoring safety circuits within industrial automation systems.
