Deskripsi
Main Control Boards (Motherboards)
- Type: Main control board / motherboard PCB
- Model Compatibility: MX‑05, MX‑10, MX‑20 actuators (MXA and MXB generations)
- Part Numbers: Vary by generation and revision (examples: 64‑825‑xxxx‑xx series boards)
- Series: Limitorque MX Series (non‑intrusive multi‑turn actuators)
- Brand : Limitorque
Product Overview:
The motherboard in Limitorque MX actuators is the central processing and control PCB. It integrates:
- Motor drive logic
- Torque and position feedback processing
- Relay and I/O interface
- LCD display interface
- Communication protocols (Modbus, Profibus, Foundation Fieldbus, DeviceNet depending on options)
It is the “brain” of the actuator, enabling non‑intrusive setup, diagnostics, and continuous monitoring.
Specifications (typical for MX motherboards):
| Feature | Specification |
|---|---|
| Processor | Embedded microcontroller with non‑volatile memory |
| Inputs | Torque sensor, position encoder, limit switches |
| Outputs | Relay contacts, LCD display, communication ports |
| Communication | RS‑485, Modbus RTU/TCP, Profibus DP, DeviceNet (option cards) |
| Power Supply | 24 VDC logic supply (from actuator power board) |
| Protection | Conformal coating, surge suppression, watchdog reset |
| Operating Temp | −40 °C to +70 °C |
| Compliance | NEMA 4/6, IP68 (when installed in actuator housing) |
