Deskripsi
Main Control Motherboard
• Type: Electric actuator control motherboard
• Model: TP400‑PC‑1411
• Brand: Changzhou Power Plant Auxiliary Equipment Factory Co., Ltd.
This board is part of the TP400 intelligent actuator control system family, which been working with alongside TP400‑D display panels and PLC boards.
Product Overview:
The TP400‑PC‑1411 is the main control motherboard for TP400 series intelligent electric actuators. It is the central logic and power interface board that:
- Receives and processes control signals (local, remote, PLC/DCS)
- Drives actuator motor forward/reverse
- Monitors torque, travel limits, and feedback sensors
- Interfaces with the TP400‑D series LCD display/HMI boards
- Provides protection functions such as over‑torque, phase loss, and travel limit cut‑off
It is designed for multi‑turn and quarter‑turn electric actuators in heavy‑duty industrial environments.
Specifications (typical for TP400‑PC series boards):
