1. The AI-6016NPN represents a 16-channel NPN output temperature control board. It is designed to work with temperature acquisition modules using thermocouple or RTD inputs and communicates via a dedicated high-speed protocol. This model does not include input functionality and must be integrated with Yudian's measurement and acquisition modules through ALINK networking technology to form a complete temperature control system.

2. The AI-6032NPN represents a 32-channel NPN output temperature control board. It supports integration with thermocouple or RTD temperature acquisition modules and is capable of handling up to 32 independent PID control channels simultaneously.
