Information Technology (IT) at the component level! An Infrared (IR) Combustible Gas Sensor Module is network-enabled to provide the interface needed to your plant-wide control system, whether it be 4-20 mA, Modbus, HART, relay contacts or SentryBus. This USA-made, stand-alone smart gas sensor module is loaded with features you need. As usual, Sierra Monitor A gas detector with a Sierra Monitor pedigree, Factory Mutual approved and ready to Manage Your Gas Risk. The 5100-28-IT provides all the built-in features desired by instrumentation and safety professionals, including:

  • FM Approval for performance and safety
  • SIL-2 Certified
  • Modbus RTU RS-485 interface
  • 4-20 mA output
  • HART Interface
  • SMC Sentry digital bus interface
  • Optional Integral alarm relays – Alarm, Warning and Trouble
  • Aluminum or 316 Stainless Steel enclosure
  • Annual calibration frequency
  • %LEL or % volume
  • Interface to multiple protocols
  • Integral scrolling LED display
  • Optional remote sensor

The 5100-28-IT can be used as a 4-20 mA component or as a Modbus RTU node. For higher level system capability the module can interface directly to Sierra Monitor’s Sentry Controller. As part of a Sentry system the user gains capability of system Modbus serial communications, extensive diagnostic features, area and zone alarm management, WebServer interface and multiplexing sensor connections.

Factory Mutual (FM) Approval for performance, electrical safety and environmental parameters including Class I, Div. 1, Groups C, D and Class I, Zone 1, Group IIC. The 5100-28-IT is also SIL-2 Certified and meets NFPA-72 requirements for gas detectors.

Most combustible gases absorb infrared light energy at defined wavelengths, providing an absorption signature for that gas. The principle of an infrared detector is based upon the absorption of the infrared light at a specific wavelength as it passes through the gas. The more of the absorbing gas that is present, the more light is absorbed. The detector measures the energy from an infrared light beam at a wavelength that is absorbed by the gas and compares it to the energy emitted by the source. The difference in energy received by the detector indicates the level of gas in the atmosphere.

Features

  • Non-intrusive calibration, menu driven system
  • Network compatible with Modbus, 4-20mA, Sentry bus, HART, relay interface
  • FM Approved for performance and hazardous area operation, Class I, Div. 1, Group C, D, with NEMA 4X enclosure rated for -40 o to 176 o F areas
  • SIL-2 Certified
  • Local scrolling display

Benefits

  • Able to easily and quickly calibrate module without declassifying the area
  • Easy to install in a variety of field applications plus easy to obtain critical safety information wherever needed
  • For safe and reliable operation in hazardous areas
