Furthermore, the module applies channel-to-channel isolation to reduce electrical interference between field inputs. Each input channel monitors discrete voltage states from switches, relay contacts, and digital field devices, while the module transfers validated status information through the Series 8 I\/O communication structure.\u003c\/p\u003e\n\u003cp\u003eAdditionally, the module architecture supports galvanic isolation between field wiring and internal logic circuits.
