A common troubleshooting error is miswiring the "Common" terminal. On HZGD-232, Outputs 1–4 share a common terminal (C1), while outputs 5–8 share another (C2). Attempting to mix voltages on the same common block will result in a short circuit.

(e.g., Engineering, Business/Manufacturing, Law, or Science?)

This article provides a thorough, technical breakdown of HZGD-232, covering everything from its electrical characteristics to its role in large-scale control systems.
