Arburg ↔ Thermoplay Hot Runner Wiring
Proportional regulator / Hot runner interface wiring documentation
Date: 11.11.2023
Overview
This document describes the wiring between the Arburg machine connectors and the Thermoplay hot runner connector.
⚠️ Important: Heater zone pinouts and J-type thermocouple (TC) pinouts use different pin assignments on each side.
Thermoplay Connector Pinout (M / F)
From the Thermoplay connector label (Image 2):
| Function | M-side Pin (+) | F-side Pin (-) |
|---|---|---|
| ZONE 1 | 1 | 13 |
| ZONE 2 | 2 | 14 |
| ZONE 3 | 3 | 15 |
| ZONE 4 | 4 | 16 |
| ZONE 5 | 5 | 17 |
| ZONE 6 | 6 | 18 |
| TC 1 | 7 (+) | 19 (−) |
| TC 2 | 8 (+) | 20 (−) |
| TC 3 | 9 (+) | 21 (−) |
| TC 4 | 10 (+) | 22 (−) |
| TC 5 | 11 (+) | 23 (−) |
| TC 6 | 12 (+) | 24 (−) |
Arburg Machine Connector Pinout
Heater Zones (connectors -4X4 / -4X2)
| Arburg Zone | Pin (+) | Pin (−) |
|---|---|---|
| Heater 1 | 1 | 2 |
| Heater 2 | 3 | 4 |
| Heater 3 | 5 | 6 |
| Heater 4 | 7 | 8 |
| Heater 5 | 9 | 10 |
| Heater 6 | 11 | 12 |
Each heater zone uses a pair of adjacent pins (odd = +, even = −).
Thermocouple Inputs — J-Type (connectors -4X3 / -4X1)
| Arburg TC | Pin (+) | Pin (−) |
|---|---|---|
| TC 1 | 13 | 14 |
| TC 2 | 15 | 16 |
| TC 3 | 17 | 18 |
| TC 4 | 19 | 20 |
| TC 5 | 21 | 22 |
| TC 6 | 23 | 24 |
TC signals are J-type thermocouples. Polarity must be respected — reversed polarity will cause incorrect temperature readings.

Key Differences — Arburg vs Thermoplay
| Property | Arburg Side | Thermoplay Side |
|---|---|---|
| Heater pair logic | Adjacent pins (1+2, 3+4, …) | Split across M/F halves (1/13, 2/14, …) |
| TC logic | Sequential pairs (13+14, 15+16, …) | Offset by 12 pins (7/19, 8/20, …) |
| TC type | J-type | J-type |
| Zones supported | Up to 6 | Up to 6 |
Notes
- Always verify wiring with a multimeter before powering up.
- Mislabelled or swapped TC wires will cause temperature runaway or zone shutdown.
- Heater zones carry mains voltage — ensure the machine is locked out before working on wiring.
