Sensor Input
Connections
Make sure that you are using the appropriate thermocouple and extension wire. Connect the negative lead
(generally colored red in ISA-type thermocouples) to contact #9; connect the positive lead to contact #10.
Extension wires must be the same polarity as the thermocouple.
Thermocouple circuit resistance should not exceed 100 ohms for rated accuracy; errors will occur
at higher resistance values. If shielded thermocouple wire is used, terminate the shield only at
panel ground.
Use wire with a resistance no greater than 10 ohms. An error of 0.2° F will result for each
additional 10 ohms of resistance encountered. If shielded RTD wire is used, terminate the shield
only at panel ground.
Note: For 2 Wire RTD
Jumper 8 & 9
The Series 16 accepts input from 2- or 3-wire, 100 ohm platinum resistance temperature detectors (RTDs).
Connect 2-wire RTDs to contacts #9 and #10, with a jumper across contacts #8 and #9. Keep leads short
and use heavy gauge copper extension wire, if necessary, to minimize lead resistance. For long runs,
3-wire RTDs should be used.
