SEC 3100 LIM (Logic Input Module) from SEC

Manufacturer:

A non-SEC device with normally open contacts is wired to the SEC 3100 LIM (Logic Input Module) from Sensor Electronics. The SEC 3100 LIM receives a Low and High contact closure from the device, converts the input signal into a digital signal compatible with the SEC 3100 transmitter. It is factory programmed with the following customer variables:

  • Device Name
  • Range
  • Unit of Measure
  • Calibration Value

The SEC 3100 visually displays the variables on the LCD the same as if the SEC 3100 had an SEC gas detector connected. The 3100 transmitter reports the foreign status bidirectional to the SEC 3500 HMI Operator Interface via the MODBUS RS485 communication network. The SEC 3100 LIM can be installed in the SEC 3100 explosion proof transmitter housing using a taller window dome.

The SEC 3100 accepts one device input for Low Alarm and High Alarm. Examples of switch contact devices that can be used with the SEC 3100 LIM are:

  • Open Path Gas Detectors

  • Temperature Switch
  • Pressure Switch
  • Air Flow Switch
