Wiring SIMs

There are two methods for wiring SIMs. You can assign sensor locations in the setup file and then wire the
sensors according to the Setup Report, or you can buy pre-wired SIMs or wire the SIMs yourself and then create
a setup that reflects the sensor locations. This section shows you how to wire SIMs yourself.
Procedure
1. Loosen the two screws in the top of the SIM and open the cover.
2. Using appropriate thermocouple wire, cut lengthwise through the outer insulation to separate the red and
blue wires, remove the resulting excess exterior sheathing, and then strip back each wire approximately ½
inch in order to make the connection with the SIM connectors. Connect the positive (+) lead to the positive
(+) connector and the negative (-) lead to the negative (-) connector. The negative thermocouple lead is
normally red, in conformance with ANSI standards. For Type T thermocouples, the positive lead is blue.
3. When validating moist heat processes, thermocouples with a sealed PTFE tip should be used with a drip cut
through the outer insulation close to the SIM module to reduce the possibility of drawing moisture into the
SIM. To add a drip cut, remove 4 inches (10 cm) of the outer insulation from each thermocouple at a point
where natural drainage can take place to prevent water reaching the terminal screws.
4. AMPHENOL ADVANCED SENSORS also recommends shaving open about 1/4 inch from each of the red
and blue inner wire jackets at opposite ends of the outer insulation drip cut to allow condensate drainage
from within the individual wires. If moisture does collect in the SIM, remove the SIM from the instrument,
open, and allow to air dry before storage.
5. Connect dry contact inputs directly to the SIM connectors.
6. Connect voltage inputs (up to 10 VDC) to the SIM connectors. Connect the positive (+) lead to the positive
(+) connector and the negative (-) lead to the negative (-) connector.
7. For current applications, connect a 250Ω precision shunt resistor to the SIM connector in parallel with the
input leads. The 250Ω resistor converts a 4-20 ma signal to 1-5 volts. Connect the positive (+) lead from the
power supply to the positive (+) SIM connector, the positive (+) lead from the device to the negative (-) SIM
connector, and the negative (-) lead from the device to the negative (-) power supply connector.
8. Once all sensors are connected, route the wire harness around the terminal connectors and out the drain
hole. Secure the wire harness with tie wraps.
9. Close the SIM cover and tighten the screws.
