RMC Module • 23 • Chapter 2 Install and Wire

Warning: ç

Use National Electric (NEC) or other

country-specific standard wiring and

safety practices when wiring and

connecting this controller to a power

source and to electrical sensors or pe-

ripheral devices. Failure to do so may

result in damage to equipment and

property, and/or injury or loss of life.

Note:

Maximum wire size termination and

torque rating:

• 0.0507 to 3.30 mm

(30 to 12 AWG)

single-wire termination or two 1.31

(16 AWG)

• 0.8 Nm (7.0 in-lb.) torque

Note:

Adjacent terminals may be labeled

differently, depending on the model

number.

Note:

To prevent damage to the controller,

do not connect wires to unused ter-

minals.

Note:

Maintain electrical isolation between

digital input-outputs, switched dc/open

collector outputs and process outputs

to prevent ground loops.

Note:

If the last two digits of the part number

are "12", this equipment is suitable for

use in CLASS I, DIVISION 2, Groups A,

B, C and D or Non-Hazardous locations

only. Temperature Code T4

Warning: ç

Explosion Hazard – Substitution of

component may impair suitability for

CLASS I, DIVISION 2.

Warning: ç

Explosion Hazard - Do not disconnect

while the circuit is live or unless the

area is known to be free of ignitable

concentrations of flammable sub-

stances.

Input 1, 2, 3, 4 Thermistor RMC Part # Digits 4, 6, 8, 10

Slot A, B, D, E

• >20 MΩ input impedance

Input 2: RMCxx(2,6)xxxxxxxxx

Input 3: RMCxxxx(2,6)xxxxxxx

Input 4: RMCxxxxxx(2,6)xxxxx

Input 1, 2, 3, 4 RTD RMC Part # Digits 4, 6, 8, 10

2-wire

RTD

Slot A, B, D, E

3-wire

RTD

Slot A, B, D, E

• platinum, 100 and 1,000 Ω @ 0°C

• calibration to DIN curve (0.00385 Ω/Ω/°C)

• 20 Ω total lead resistance

• RTD excitation current of 0.09 mA typical.

Each ohm of lead resistance may affect the

reading by 0.03°C for 100 Ω.

• For 3-wire RTDs, the S1 lead (usually

white) must be connected to R terminal

• For best accuracy use a 3-wire RTD to com-

pensate for lead-length resistance. All three

lead wires must have the same resistance.
