Operation
The SEC 3100 AIM is used in conjunction with the SEC 3100 explosion proof transmitter or SEC 3100 DIN
transmitter. A non-SEC device with a conventional analog 4 - 20 mA output is wired to the SEC 3100 AIM.
The SEC 3100 AIM receives a sourced 4 - 20 mA signal from the device, converts the analog signal into a
digital signal compatible with the SEC 3100 transmitter. The SEC 3100 AIM is factory programmed with
the following customer supplied 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 SEC 3100 transmitter reports the foreign device status bidirectional to the SEC
3500 HMI Operator Interface via the MODBUS RS485 communication network. The SEC 3100 AIM can
be installed in the SEC 3100 explosion proof transmitter housing using a taller window dome.
The SEC 3100 AIM accepts one device input. Examples of 4 - 20 mA devices that can be used with the
SEC 3100 AIM are:
Open Path Gas Detectors
Fire Detectors
Temperature Transmitter
Pressure Transmitter
Pyrolyzers
