Operation / Description

The SEC 3120 provides dual interface capabilities for the SEC 3000 Gas Detector family, SEC Millenium and
SEC 5000 Infrared Gas Detector families.

The SEC 3120 features:

•  Dual sensor interfacing to enable like-sensor redundancy or control or dissimilar sensor types
•  Back lighted LCD for Gas Level/Unit Parameter display
•  Four (4) Alarm/Fault Relays configurable for alarm set points, latching and multi-sensor relay logic
•  An isolated RS485 Modbus interface provides reliable communication in noisy environments and

eliminates “Ground Loop” problems

• Three magnetic switches for local configuration and calibration without compromising explosion

proof protections

• 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.
