only 22.5 mm.
• The Temperature Controller itself can be replaced without
changing terminal wiring.
• Use in combination with a compact Setting Display Unit to
reduce communications programming requirements.
• Front-panel LED indicators for easy operation monitoring.
• Power supply and communications wiring not required between
Units when mounted side-by-side.
• CompoWay/F communications protocol supported.
• UL, CSA, and CE Marking compliance.

■ Connection Diagrams
• Voltage output (control output) is not electrically isolated from internal circuitry. Therefore, when using grounded thermocouples, do not ground
control output terminals. (Doing so may result in temperature measurement errors due to unwanted current paths.)
• There is basic insulation between the power supply inputs and outputs for this product. If reinforced insulation is required, connect the input and
output terminals to equipment without any exposed charge-carrying parts, or to equipment with basic insulation sufficient for the maximum
operating voltage of the power supply and the inputs and outputs.
• To comply with the standards for noise terminal voltage for class A in EN 61326, install a noise filter (Densei Lamda MXB-1206-33 or the
equivalent) to the DC power line as close as possible to the Temperature Controller.

only on the number of switching operations performed by the relay
but also on the service life of the internal electronic components. The
service life of these components depends on the ambient
temperature; it will be shorter if the ambient temperature is high, and
longer if the ambient temperature is low. For this reason, the service
life of the product can be lengthened by keeping the inside of the
E5ZN at a low temperature.
If several Units are mounted side-by-side or are arranged vertically,
the heat generated may cause the internal temperature of the Units
to rise, reducing service life. To prevent this, take steps to ensure that
the Units are cooled, such as installing fans.
Ensure, however, that the terminals are not also cooled, otherwise
correct temperature measurement will not be possible.
Measurement Accuracy • To dismount, insert a flat-bladed screwdriver into part C, pull the
hook down, and then lift the bottom part of the E5ZN upwards.
When extending the lead wires for thermocouples, use a
compensating conductor appropriate for the type of thermocouple
When extending the lead wires for platinum resistance
thermometers, use lead wires with a low resistance, and make the
resistance in the 3 lead wires equal.
Make sure that the temperature sensor type and the input type of the
E5ZN are the same.
Mount the E5ZN horizontally.
If significant errors occur, check that input compensation has been

The degree of protection is given below. Parts for which the degree of Stopper
protection is not clearly indicated, and parts with IP@0 ratings (where
@ is not 0) do not have waterproof specifications. • Mount the E5ZN at least 30 mm away from other devices to ensure
