It offers an efficient solution for collecting and outputting analog signals directly at the machine level, eliminating the need for extensive wiring and protective enclosures. Operating under the IO-Link Specification V1.1 (Class B), this module establishes point-to-point communication with an upstream master to process signals with high precision.\u003c\/p\u003e\n\n\u003cp\u003eThis IO-Link box is equipped with two analog inputs and two analog outputs, all of which are parameterizable per channel. Engineers can configure each connection individually to operate with standard voltage signals (-10 to +10 V or 0 to 10 V) or current signals (0 to 20 mA or 4 to 20 mA). This flexible architecture permits the direct connection of diverse industrial sensors and actuators within a single hardware footprint.\u003c\/p\u003e\n\n\u003cp\u003eConstructed with a robust polyamide (PA6) housing, the \u003cstrong\u003eBECKHOFF EPI4374-0002\u003c\/strong\u003e features an IP65, IP66, and IP67 protection rating. This design allows for direct mounting on machine frames in harsh industrial environments, ensuring resistance against moisture, dust, and mechanical stress while optimizing field installation
