Banner Engineering ES-UA-5A E-Stop Interlock Monitoring Safety Module

The Banner Engineering ES-UA-5A (66091) is a compact safety relay module designed to monitor E-stop, rope-pull, and interlock devices, delivering four normally open safety outputs up to 6 A and an auxiliary normally closed contact with two solid-state outputs for integration with safety circuits. It accepts either 115 V AC or 12–24 V DC supply, features one safety input channel configurable as 2 NC or 1 NC, and includes self-checking circuitry with auto or manual reset. The unit uses a removable terminal block and occupies a 45 mm-wide footprint (84 mm H x 45 mm W x 118 mm D); it is IP20 rated and rated for operation up to 50°C with up to 90% humidity at 50°C. Safety outputs are 4 NO at 6 A; the auxiliary output includes 1 NC at 5 A and two solid-state outputs at 0.1 A. Designed for E-stop, rope pull, and interlock monitoring, it is part of Banner's ES-UA/VA family, with a recovery time of 350 ms, typical response time of 25 ms, and electrical life of up to 1,000,000 cycles at 450 VA; it carries Safety Category 4 and SIL 3 ratings reflecting its role in safety-related control circuits.
