Digital temperature regulators

Ideal for temperature regulations with HERZ air heaters

Ideal for temperature regulations with HERZ air heatersThe regulators of the ETR series are versatile PID temperature regulators in standard DIN format 1/32(ETR48-24) and 1/16 (ETR48-48) with self-optimization.

Universal input
Different temperature inputs:thermocouple, platinum resistance thermometer,infrared thermometer.

(optional analogue inputs)

Optimization
Auto-adaptation and self-optimization available.Auto-adaptation is possible even during selfoptimizationexecution.

Safety / Certificates
Waterproof front construction (NEMA4X;corresponds to IP66).Corresponds to safety regulations UL, CSA, andIEC and is marked with the CE symbol.

Digital communication (optional)
RS485 enables easy parameterization vianotebook / PC.

Exact regulation
A reliable PID control algorithm enables a stable and"straight" process regulation.

Universal input
The ETR48-48 universal input circuit is provided with aanalogue / digital converter. It scans the input with 9 Hzand constantly corrects the drift. This ensures highprocess stability and fast response to changes.

Easy handling
A bright and clearly visible LED display shows the actualvalue as well as error messages. The target value canbe modified by pressing the "more" or "less" button.

Digital communication (optional)
Communication interface RS485, RS422 or RS232supports Modbus®, DeviceNet®.
