Features
Improved Functions for a Wider Range of Application
Control Analog Values, such as Pressures, Flowrates, Voltage Outputs (to Drive SSRs) for Both Heating and
and Levels Cooling Control. Can Be Used for Alarms to Provide
Three Alarm Outputs.
The new E5CN Series now also includes models that accept analog
inputs, enabling control applications other than for temperature,
Voltage outputs can be used for both heating and cooling for Models
including pressure, flowrate, level, humidity, and weight control.
with Two Control Outputs. Also, control output 2 can be set for use as
an alarm output, to enable using up to three alarm outputs.

Faster Sampling at 250 ms
Three-phase Heater Burnout Detection
The previous sampling time of 500 ms has been reduced by half to
250 ms. This enables the new E5CN to handle application requiring
