SILO2 SIL2-capable Oxygen Analyzer
SIL2-capable oxygen analyzer with remote hazardous-area sensor for inertization safety applications.
Key Features
- SIL2-capable oxygen measurement (IEC 61508)
- Inbuilt analyzer and galvanic isolation barrier in one device
- Sensor design for installation in Zone 0 hazardous areas
- Measurement range 0–25 % O2
- Analog 4–20 mA output; RS485 (not SIL-capable)
- 2 configurable alarm relays, 1 fault alarm relay and 1 transistor output
- 35 mm DIN-rail mounting
Overview
SILO2 is a low-maintenance oxygen analyzer with a remote sensor approved for hazardous-area use. Designed for OEMs and end-users in inertization applications such as centrifuges, reactors, mills, glove boxes and vent headers, it uses two continuous self-monitoring microprocessors to deliver fail-safe oxygen measurement in safety-critical applications requiring compliance with IEC 61508 SIL2.
Working Principle
A remote intrinsically safe O2 sensor (OC-25/OC-25M, OC-26/OC-26M or OC-200 series) is connected through the analyzer's built-in galvanic isolation barrier. Two continuously self-monitoring microprocessors evaluate the signal and drive a 4–20 mA output, configurable alarm relays and a fault relay.
Applications
Benefits
- Fail-safe measurement for safety-critical inerting
- Ease of integration for OEM applications
- I.S. sensor cable lengths of 5, 10 or 15 m
