iMFD Sensor Module SM-FluidTemp
*Please read the instructions completely through at least once before proceeding with the
installation to minimize errors.
*Double check polarity of power before powering it on for the first time.
Overview:
(Figure 1) (Figure 2)
1. Connects to 12V-18V power source.
2. Analog outputs (0-5V linear output) *For sensor #1 ONLY
3. Termination jumper. Closed for first SM in iMFD daisy chain.
4. Connects to next SM in iMFD daisy chain or to first DM
5. Connects to previous SM or unconnected if first SM in iMFD daisy chain
6. Connects to PLX Fluid Temp Sensor. Up to 2 sensors can be connected for 2 channel operation.
7. Fluid Temperature Sensor. (*Using a sensor not provided by PLX Devices may lead to inaccurate readings due to a
mismatch in calibration)
8. 24k Gold Ring Terminal
9. 24k Gold Female Disconnect Terminal
10. Molex Connector Terminals
11. Molex 2 Pin Connector
Install the Fluid Temperature Sensor:
1. The PLX Fluid Temperature probe screws into a 1/8 NPT tap.
2. Connect the fluid temperature sensor with the provided 2 pin Molex connector according to the following diagram.
Connections can be made by crimping the terminals or soldering the terminals with the provided wire. *Note the orientation
of the Molex 2 pin connector. A reverse connection will result in inaccurate readings and may damage the device.
