⁄16 DIN Temperature Controllers
The CN350, CN360, and CN370
Series controllers are economical
and easy to use. Models are
available with digital, deviation,
or non-indicating display, for
J, K, R, and S thermocouples or
100 Ω platinum RTD input. The

±1.5% FS + 1 digit
RTD Input: ±1.0% + 1 digit
Resolution: 1°C or °F
(P2CX range: 0.1°C)
Output Types: SPDT mechanical relay,
240 Vac, 2.5 A resistive load

depth behind the panel helps
conserve space and cut installation
costs. All models have a digital
thumbwheel for adjusting the setpoint.
The CN370 Series models provide
continuous digital display of the
process temperature. The CN360
Series models indicate whether the
process temperature is within ±1.5%
FS of the setpoint or above or below
setpoint. The CN350 Series models
are non-indicating.
These controllers are time
proportional with manual reset,
and can be converted to on/off
control by changing internal
jumpers. The proportional band
is fixed at 4%.
Two types of outputs are available.
A 2.5 A (SPDT) mechanical relay is
for use with systems that can use a
30-second cycle time. With
an external solid state relay, loads
to 5 A can be accommodated.
For systems that require a faster
cycle time, the DC solid state driver
output should be used. This has
a cycle time of approximately
3 seconds and can control high
AC loads by using a DC-controlled
solid state relay.
