⻬ Compatible with Standard 35 mm DIN Rail

The CCT series DIN rail signal conditioners are
designed to accept a broad range of input signals, such
as ac and dc voltage and current, frequency,
temperature (thermocouple and RTD), and process
transducers, and provide standard process outputs of
either 0/4 to 20 mA, or 0 to 10 Vdc. The CCT series
features a modern housing design, that is easily
mounted on standard DIN rails. Connections are safely
and securely made, with input and output connections
on the opposite sides of the module.

than actual size.

Internal Design

The CCT series is designed using an internal plug-in
three module system that provides flexibility in selecting
and changing the power supply, input signal and output
signal. Available power supplies include 110 Vac,
220 Vac, and 24 Vdc.

Isolation

The three internal modules in each signal conditioner
(signal input, signal output and power supply) are
isolated up to 2 kVeff.

Outputs

Each CCT series signal conditioner is available with
current and voltage output (only one may be used at a
time). Available output types include 4 to 20 mA or 0 to
20 mA (jumper-selectable) and 0 to 10 Vdc.

Standard outputs are linear and proportional to the
signal input. Thermocouple input modules feature
special circuitry to linearize the output to the actual
temperature, and not to the non-linear signal produced
by thermocouple sensors.

Integrators

The CCT integrator signal conditioners accept either
voltage or current signals, and provide a frequency
pulse output. This pulse output can be used as input
signals for PLCs or other industrial controls.

Additional Features

Additional models in the CCT series include the FAR
power supplies, that can be used with the CCT-80
strain gage transmitter, to provide wheatstone bridge
excitation. The loop-powered galvanic isolator model
CCT-100 can be used in any application where input to
output isolation is required. The CCT-100 provides up
to 2 kVeff isolation between the input and output
terminals.
