About the product
EHRTC-PM1 is a semi-modular temperature control system designed to control hot runner heaters in plastic injection moulds precisely and reliably. With a 3200 W external power stage per zone, PID Auto-Tune and Stand-By functions, it delivers energy efficiency and stable temperatures on your production line.

Key features
- Semi-modular rack system.
- External power stage: 3200 W per zone. Easily accessible power stage (input 5–30 V DC, output 24–240 V AC, 25 A solid state relay).
- P.I.D. control; AUTO-TUNE calculates and sets the PID parameters automatically.
- Maximum operating temperature 537 °C (999 °F).
- Works with J type (Fe-CuNi) and K type (NiCr-Ni) thermocouples; selectable in the program.
- STAND-BY: pauses production at a holding temperature and restarts with a single key.
- Accuracy of ±0.5 % of full scale.
- Automatic switch to proportional (percentage) operation on thermocouple failure.
- Operation without thermocouple (proportional / manual mode).
- Direct, easy access to the set value.
- Output (power stage) can be switched off with one key without cutting power.
- OFFSET adjustment (−50 °C … +50 °C).
- Adjustable maximum set value limit.
- Factory reset function.
- Automatic fast protection fuse in every module.
- Optional cable length and connector configuration.
- 1, 2, 4, 6, 8, 10 and 12 zone options; expandable on customer request.

Frequently asked questions
What is the difference between EHRTC-PM1 and EHRTC-RM2?
PM1 is a semi-modular system whose power stage sits outside the unit in an easily accessible section. RM2 is a fully modular rack: each zone module carries its own power stage and the unit is fan cooled. PM1 suits small and medium zone counts; RM2 suits heavy production and fast module swaps.
Which thermocouple types are supported?
J type (Fe-CuNi) and K type (NiCr-Ni). The sensor type is selected in the controller program.
Does production stop if a thermocouple fails?
No. On thermocouple break or failure the controller switches automatically to proportional (percentage) output and raises an alarm, so you can continue in a controlled way.
How many zones are available?
1, 2, 4, 6, 8, 10 and 12 zones as standard. Higher zone counts are configured on request, e.g. two 12-zone units for 24 zones.
Try it on your own mould before you buy
We ship an EHRTC demo unit matching your zone count to your plant, with remote support for installation and parameter setup. Trial terms and duration are agreed together.
- PM1 or RM2 demo unit sized to your zone count
- Remote support for installation, Auto-Tune and alarm setup
- Decide with your own production data at the end of the trial
