Warning:

Use National Electric (NEC) or

other country-specific standard

wiring and safety practices when

wiring and connecting this con-

troller to a power source and to

electrical sensors or peripheral

devices. Failure to do so may re-

sult in damage to equipment and

property, and/or injury or loss of

life.

Figure 7a — Thermocouple Input 1

(all model numbers)

Thermocouples are polarity sensitive. The negative lead (usually red) must be

connected to terminal 9.

• Input impedance: >20 MΩ

Figure 7b — Thermocouple Input 2

PDD _-_ _ _ _-_ _ _ _

Thermocouples are polarity sensitive. The negative lead (usually red) must be

connected to terminal 5.

• Input impedance: >20 MΩ

• Input 2 isolated from Input 1

Figure 7c — 2-Wire RTD Input 1 (100 Ω DIN curve 0.00385

Ω/Ω/°C)

(all model numbers)

Terminals 9 and 11 must be shorted for a two-wire RTD.

• Nominal excitation current: 250 µA

Figure 7d — 3-Wire RTD Input 1 (100 Ω DIN curve 0.00385

Ω/Ω/°C)

(all model numbers)

The S1 lead (usually white) must be connected to terminal 10.

• Nominal excitation current: 250 µA
