This document introduces the features and characteristics of TH-4108AH and TH4108-M/A inverter remote controllers, including remote control of inverter startup, stoppage, acceleration, deceleration, forward and reverse functions through RS485 network, and display of inverter's set frequency, actual frequency and other status information.
The TH-4108AH/TH4108-M/A remote controller is an intelligent device for remote operation of frequency converters via RS485. It supports start, stop, speed increase/decrease, forward/reverse control and displays set and actual frequencies, with a communication range up to 1200 m.
The document covers appearance, button layout, LED indicators, electrical wiring, parameter configuration, fault handling, and user precautions, providing step‑by‑step instructions for both M‑type and A‑type models. This manual is written in Chinese.
| Dimensions (M type) | 48 × 96 mm, opening 45 × 93 mm, depth 65 mm |
|---|---|
| Dimensions (A type) | 80 × 160 mm, opening 76 × 151 mm, depth 135 mm |
| Power Input (M type) | 9‑36 V DC or AC |
| Power Input (A type) | 220 V AC (lines 220N/220L) and 12 V DC (POWER/GND) |
| Communication Distance | Up to 1200 m (9600 bps) |
| LED Indicators | RUN, FWD/REV, ERR, COM |
| Button Count | 5 buttons per controller |
When a fault code is displayed (SV window = P01) and the PV window shows a value greater than 0, press the FWD/REV key to send a fault‑reset command.
The controller can communicate up to 1200 meters at 9600 bps.
There are four LEDs indicating RUN (operation), FWD/REV (direction), ERR (error), and COM (communication).
