Built for demanding two-hand control safety applications, the RLY3-HAND100 Sick Two Hand Safety Relay provides advanced protection with support for Type III C control devices as specified by EN ISO 13851. Engineered to meet SIL 3 (IEC 61508), Category 4, and PL e (ISO 13849-1) safety levels, this safety relay ensures reliable actuation and operator safeguarding with a 20-year mission time.
This model is equipped with 4 safety-capable inputs for connecting 2 separate control devices, each with both normally closed and normally open configurations. It also includes 1 EDM input for external device monitoring. The output side features 2 enabling current paths (safe) and 1 application diagnostic output (not safe). The positively guided N/O contacts are constructed from silver alloy with gold flashing, supporting switching voltages from 10 V to 230 V (AC/DC) and currents up to 6 A.
The RLY3-HAND100 runs on 24 V DC (16.8 V to 30 V) with a ripple of ≤ 2.4 V, consuming ≤ 2.5 W of power. It features fast switching with a 10 ms response time, and operates across challenging environments with a temperature range of –25 °C to +55 °C and up to 95% non-condensing humidity. The relay uses front connectors with spring terminals for quick, secure wiring and includes LED indicators for intuitive diagnostics. Housed in a compact IP20 enclosure, with dimensions of 18 mm x 124.6 mm x 85.5 mm, it offers space efficiency without compromising performance.
