2.4.2 Temperature Probe Connections
The TMP100 temperature probe connections are made by connecting to the 12-pin terminal
strip on the top of the unit. First, remove the four screws at the corners of the unit detaching
the splash guard from the unit. On the bottom of the splash guard, you will find a label
detailing the wire connection to pin number assignments, which are repeated in the table
below.
Pin # Signal Name Connection
1 T0+ Exhaust Gas Temperature Probe 0 (positive terminal)
2 T0- Exhaust Gas Temperature Probe 0 (negative terminal)
3 T1+ Exhaust Gas Temperature Probe 1 (positive terminal)
4 T1- Exhaust Gas Temperature Probe 1 (negative terminal)
5 T2+ Temperature Probe 2 (positive terminal)
6 T2- Temperature Probe 2 (negative terminal)
7 T3+ Temperature Probe 3 (positive terminal)
8 T3- Temperature Probe 3 (negative terminal)
9 T4+ Temperature Probe 4 (positive terminal)
10 T4- Temperature Probe 4 (negative terminal)
11 T5+ Temperature Probe 5 (positive terminal)
12 T5- Temperature Probe 5 (negative terminal)
Before attempting to connect the TMP100 to the temperature probes, determine the type of
system you will be monitoring. The TMP100 supports the connection and monitoring of two
different system types; 1) Exhaust Gas Temperature probes (Section 2.4.2.1), or 2) thermistor
type probes (ring/under bolt probes, immersion probes, and ambient air probes; please see
Section 2.4.2.2).
