AH500 Motion Control Module Manual If the frequency of input signals is less than 50 kHz and there is not much noise, these high-speed input terminals can be connected to a direct-current (sinking/sourcing) power supply whose voltage is in the range of 5 V to 24 V, as shown below. Take AH20MC-5A for instance. Sinking: X0.8+ + 5~24V NPN sensor Sourcing: PNP sensor + 5~24V X0.8+ 2.2.3 Wiring Output Terminals 1. Transistor output circuit 2-26 Load Trigger Y0.8 Direct-current power supply Emergency stop Fuse
