Modular Temperature Controller
E5ZN
CSM_E5ZN_DS_E_3_2
New DIN Track Mounting Temperature
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.

Note: 1.
Terminal Units are required for wiring. Purchase separately.
2.
When connecting the load of the controlled system, heat control output or cool control output can be allocated to the control output or
auxiliary output. When connecting a recording device or Digital Panel Meter, transfer output can be allocated to control output or auxiliary
output 3 or 4 of analog output models.
3.
When using the heater burnout alarm, purchase a Current Transformer (E54-CT1 or E54-CT3) separately.
4.
When using heating and cooling control functionality, the auxiliary output will be either heating control output or cooling control output.
5.
Analog input and infrared temperature sensors (ES1B) can also be used with thermocouple models
.

Note: 1.
When using 2 or more E5ZNs mounted side-by-side, use the E5ZN-SCT18S-500 for the second and subsequent Units. When using
E5ZNs separately, be sure to use the E5ZN-SCT24S-500.
