Action

Feed temperature sensor input leads through conduit entrance in housing. Strip 1/4 inch (6.35 mm) of insulation from input leads.

If input is from …

Then…

2-wire RTD

connect RTD leads to

 

terminals 1 and 3.

 

See Figure 15.

3-wire RTD

connect RTD leads to

 

terminals 1, 2, and 3.

 

See Figure 15.

4-wire RTD

connect RTD leads to

 

terminals 1, 2, 3, and 4. See

 

Figure 16.

2-wire Thermocouple

connect minus (–) lead to

 

terminal 1 and plus (+) lead to

 

terminal 3. See Figure 16.

Feed loop power leads through conduit entrance on other side of electronics housing opposite RTD wiring entrance.

 

ATTENTION

The transmitter accepts up to 16 AWG (1.5 mm

diameter) wire.

 

 

 

 

Strip 1/4 inch (6.35 mm) of insulation from leads. Observing polarity, connect positive loop power lead to SIGNAL + terminal and negative loop power lead to SIGNAL – terminal.
