Controller
• Two channels of temperature control available despite width of
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.

Installation
■ 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.
Using with the E5ZN-SCT24S-500

Safety Precautions
Refer to Safety Precautions for All Temperature Controllers.
!WARNING
Provide at least one power-interruption switch to
ensure that the power is OFF before wiring. Not
doing so may result in electric shock.
13.Install switches or circuit-breakers so that the user can turn the
power OFF immediately, and indicate these accordingly.
14.Do not use the product in the following locations:
• Locations subject to dust or corrosive gases (in particular,
sulfide gas and ammonia gas)
• Locations subject to freezing or condensation
• Locations exposed to direct sunlight
■ Safety Precautions
• Locations subject to vibrations or shocks
Observe the following points to ensure safe operation.
• Locations subject to heat radiated directly from heating
equipment
1. Use and store the product within the specified temperature and
humidity ranges. Cool the product (e.g., using fans) where
necessary.
2. Do not touch the electronic components or pattern of the PCB.
Hold the product by the case.
3. To ensure proper heat dissipation, leave a space around the
product. Do not block the product’s ventilating holes.
4. Use at the rated power supply voltage with the rated load.
5. Be sure to connect terminals with the correct polarity.
6. Perform wiring using crimp terminals of the specified size. ([email protected]: M3.0, width 5.8 mm max.; E5ZN-SDL: M3.5, width
7.2 max.)
7. Be sure to use wires satisfying the following specifications for
connection using bare wires.
Power supply terminals: AWG 22 to 14
Other terminals: AWG 28 to 16
(Length of exposed part: 6 to 8 mm)
8. Do not connect anything to unused terminals.
9. Ensure that the rated voltage is reached within 2 seconds of
turning power ON.
10.Allow 30 seconds’ warm-up time.
11.Install the product as far away as possible from devices that
generate strong, high-frequency noise and devices that generate
surges.
12.Keep wiring separate from high-voltage power lines or power lines
carrying large currents. Do not wire in parallel with or together
with power lines.
• Locations subject to exposure to water or oil
• Locations subject to intense temperature changes
15.When the Terminal Unit is separated from the Temperature
Controller, under no circumstances touch the electrical
components or apply shock to the Temperature Controller.
16.Do not use solvents to clean the product. Use commercial
alcohol.
17.After wiring is completed remove the dust-protection label to allow
proper heat dissipation.
18.When mounting the Temperature Controller to the Terminal Unit,
make sure that the hook on the side of the Temperature Controller
facing the Terminal Unit is inserted properly.
19.Install the DIN track vertically.

E5ZN
■ Precautions for Correct Use
Service Life
Use within the following temperature and humidity ranges:
• Temperature: −10 to 55°C (with no icing or condensation)
• Humidity: 25% to 85%
If the product is installed inside a control panel, the temperature
around the product (and not the temperature around the control
panel) must be kept below 55°C.
With electronic devices like the E5ZN, the service life will depend not
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.
Operating Precautions
1. A time of approximately 4 s is required after the power supply is
turned ON until the outputs turn ON. Take this time into
consideration when the Temperature Controller is incorporated in
a sequence circuit.
2. Using the product near radios, televisions, or other wireless
devices may result in reception interference.
Mounting and Dismounting
• To mount using a mounting track, first hook part A (see below) onto
the track and then push down on part B.
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
used.
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
set correctly.
Waterproofing
30 mm min.
The degree of protection is given below. Parts for which the degree of
protection is not clearly indicated, and parts with [email protected] ratings (where
@ is not 0) do not have waterproof specifications.
• Temperature Controller: IP00
• Terminal Unit: IP00
Stopper
• Mount the E5ZN at least 30 mm away from other devices to ensure
easy mounting and dismounting.
ALL DIMENSIONS SHOWN ARE IN MILLIMETERS.
To convert millimeters into inches, multiply by 0.03937. To convert grams into ounces, multiply by 0.03527.
