Overview
The WEIHONG EX22A3 Terminal Board is a specialized I/O interface module designed to simplify the connection between WEIHONG CNC motion controllers (NK/PM series) and field devices. It converts high-density controller connectors into clearly labeled screw terminals, providing robust, vibration-resistant connections for digital I/O signals. The board reduces wiring complexity, enhances installation reliability, and allows faster troubleshooting and maintenance.
Technical Data
| Parameter | Specification |
|---|---|
| Model Number | EX22A3 |
| Component Type | CNC I/O Terminal Interface Board |
Typical Applications
-
Routing and Milling Machines: Connect limit switches, home sensors, and probe inputs for X/Y/Z axes.
-
Plasma and Laser Cutters: Interface torch height controllers, ignition signals, and safety interlocks (E-stop, door contacts).
-
Spindle Control: Terminals for spindle ON/OFF, direction, and analog speed control (0–10 VDC).
-
Peripheral Devices: Connect outputs for coolant pumps, lubricators, dust collectors, and other ancillary equipment.
Benefit: Provides a professional, easily maintainable, and reliable interface between controller and field devices.
FAQ
Q1: Why use the EX22A3 instead of wiring directly to the controller?
A1: It reduces complexity, increases reliability, and provides large, vibration-resistant screw terminals, simplifying installation and maintenance.
Q2: Does the EX22A3 include signal conditioning or protection?
A2: No, it is a passive breakout board. External protection or filtering can be added as needed.
Q3: How do I know which field device connects to which terminal?
A3: Terminals are labeled on the PCB (e.g., X+, Y-, E-STOP, SPINDLE FWD). The CNC controller manual provides the definitive pin-to-signal mapping.
