Therefore, the host controller determines the command logic while the output module handles the physical signal interface.\u003c\/p\u003e\n\u003cp\u003eThe supplied information identifies the K-DO04 as a digital output module, but it does not define the exact electrical output technology, rated load current, output voltage, channel isolation, or channel count. Consequently, these parameters require confirmation from the applicable Hollysys hardware documentation before installation.\u003c\/p\u003e\n\u003cp\u003eThe module provides LED indications for module status and individual output states.

Confirm the hardware variant before connecting field loads.\u003c\/p\u003e\n\u003cp\u003eQ: Can the K-DO04 connect directly to field actuators?\u003cbr\u003eA: The module provides discrete output signals for field circuits. However, the required interface depends on the output voltage, load current, and electrical characteristics of the connected device.\u003c\/p\u003e\n\u003cp\u003eQ: Does the supplied data define hot-swap operation?\u003cbr\u003eA: No. The available information does not confirm hot-swap capability.
