Connections
RTD module connections are dependent on the application. Incorrect wiring may result in damage to the
module.
Note
Be sure that the RTD module is hard-wired to earth ground with no
smaller than 12 AWG (3.31 mm
2 ) copper wire attached to the chassis
ground terminal on the module.
Terminations
The terminal interface consists of permanently mounted connectors with screw-down compression
terminals.
RTD module connections are made with one 6-position connector, two 12-position connectors, and two
15-position connectors. Connector screw terminals accept a maximum wire size of 12 AWG (3.31 mm
2 ).
Maximum screw torque is 5 inch-pounds (0.56 N
•m) for the 12- and 15-position connectors. Maximum
screw torque is 9 inch-pounds (1.01 N
•m) for the 6-position connector.
Operating Power
The RTD module operating power input accepts 125/250 Vac/dc and tolerates voltage over the range of
90 to 270 Vac or 90 to 300 Vdc. The operating power inputs are not polarity sensitive. Operating power
terminals are listed in Table 254.
