SEC 3100 Universal Transmitter

The SEC 3100 provides interface capabilities for the SEC 3000 Gas Detector and SEC Millenium Infrared Gas Detectors.

The SEC 3100 features:

  • Back lighted LCD for Gas Level/Unit Parameter display.
  • Four (4) configurable Alarm/Fault Relays.
  • An isolated RS485 Modbus interface provides reliable communication in noisy environments and eliminates “Ground Loop” problems.
  • Three magnetic switches for local configuration and calibration.
  • Time stamped data logging using a removable non-volatile memory module. Module can be removed from the unit to allow remote data downloading and data archiving.

An optional IS barrier allows “hot” sensor replacement in rated locations. This allows the user to install pre-calibrated/pre-configured sensor boards without removing unit power while maintaining EX rating. Removable circuit board stack and detachable connectors facilitate field-wiring installation.
