Ramp/Soak Process Controller
Advanced Ramp/Soak Process
Controllers Ideal for Worldwide Use
E5AK-T offers up to eight patterns of
simple programming control (4 patterns
for E5EK-T), with 16 steps per pattern
Modular structure, one-stock type
High-accuracy: 100 ms sampling (for
analog input)
Conforms to international EMC and
safety standards.
IP66/NEMA4 (indoor use) front face
Serial communications (RS-232C,
RS-422 and RS-485) and transfer
output (4 to 20 mA)
Position-proportional control model is
offered
Heat/Cool control
24 V AC/DC types also available
Ordering Information
When ordering, order control output boards and option boards separately. Example: for a relay control output, order the E53-R output
board in addition to the standard Process Controller (E5AK-T/E5EK-T). Also specify the current transformer.

Item
Base unit
Note: 1. When using the heater burnout alarm function with a standard model, the linear output board cannot be used for the control
outputs (heat).
2. The Process Controller provides transfer outputs at 4 to 20 mA for the PV and other values and control outputs at 4 to 20 mA
for the current outputs.
