Warning:
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 peripheral
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 mm2 (30 to 12 AWG) single-
wire termination or two 1.31 mm2 (16 AWG)
• 0.8 Nm (7.0 lb.-in.) torque
Note:
Adjacent terminals may be labeled differently,
depending on the model number.
Note:
To prevent damage to the controller, do not con-
nect wires to unused terminals.
Note:
In the graphics below notice that the Slot A connector does not show labeling for the outputs. Labeling
for Slot A outputs is based on the controller part number.

Inputs
All inputs shown below represent input 1 (the only input) and are to be connected to slot A of the Limit
Control.
Process Volts and Amperes
• 4 to 20 mA @ 100 Ω input impedance
• 0 to 10V
Î
(dc) @ 20 kΩ input impedance
• Scalable
Resistance Temperature Detector (RTD)
• Platinum, 100 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 3-wire RTDs, the S1 lead must be con
-
nected to R1.
• For best accuracy use a 3-wire RTD to com
-
pensate for lead-length resistance. All three
lead wires must have the same resistance.
Thermocouple
• 2 KΩ maximum source resistance
• >20 MΩ input impedance
• 3 microampere open-sensor detection
• Thermocouples are polarity sensitive. The
negative lead must be connected to S1.
• To reduce errors, the extension wire for ther
-
mocouples must be of the same alloy as the
thermocouple.
Thermistor
• >20 MΩ input impedance
• 3 microampere open-sensor detection
