6.7.2 3-lead Resistance
Thermometer (RTD) Inputs
The three leads must have equal resistance, not
exceeding 30Ω each.
6.7.3 2-lead Resistance
Thermometer (RTD) Inputs
If long leads are necessary, it is preferable to use a 3-
lead RTD. If the RTD is to be used in a hazardous
area, a 3-lead RTD connected via a suitable Zener
barrier, must be used.

Make connections as shown in Fig 6.6.
Refer to Table B on the rear fold-out for the
default output assignment settings.
6.9 Power Supply Connections
Caution.
•
A 1A Type T fuse must be fitted in the live (+ve)
supply line.
•
The ground line must be connected to the
ground studs on the terminal block – see
Fig. 6.6.
•
Do not disturb the link between the two ground
studs.
•
The type of power supply required (AC or DC)
is stated at the time of order and can be
identified from the instrument code number:
C35X/XX0X/STD = 100 to 240 V AC
C35X/XX1X/STD = 24 V DC
