This combi module features two analog inputs and two analog outputs that are individually parameterizable for either voltage or current signals. This flexibility allows for the integration of diverse analog sensors and actuators directly into the EtherCAT network in harsh industrial environments.\u003c\/p\u003e\n\n\u003cp\u003eConstructed with a durable zinc die-cast housing, the ER4374-0002 provides excellent structural stability and high electromagnetic compatibility (EMC). It offers IP67 protection, making it highly resistant to dust, moisture, and liquids. The fieldbus connections, power supply, and signal interfaces are established via industrial-grade circular connectors, ensuring secure and stable wiring.\u003c\/p\u003e\n\n\u003cp\u003eThe integrated 16-bit resolution provides high-precision measurement and signal output. Because the inputs and outputs can be configured independently, this module optimizes space and reduces hardware variants in machine installations, serving as a versatile interface for automation and control tasks.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eCombination module with 2 analog inputs and 2 analog outputs in a single housing\u003c\/li\u003e\n  \u003cli\u003eIndividually parameterizable channels for voltage (-10 V to +10 V) or current (0\/4 mA to 20 mA) signals\u003c\/li\u003e\n  \u003cli\u003eZinc die-cast housing designed for direct machine installation without protective enclosures\u003c\/li\u003e\n  \u003cli\u003eHigh-precision signal processing with 16-bit resolution\u003c\/li\u003e\n  \u003cli\u003eStandardized industrial connections with M12 sockets for signal interfaces\u003c\/li\u003e\n  \u003cli\u003eDual M8 sockets for high-performance EtherCAT communication\u003c\/li\u003e\n  \u003cli\u003eHigh protection rating of IP67 for demanding industrial environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eDirect integration of analog sensors and actuators in decentralized machine architectures\u003c\/li\u003e\n  \u003cli\u003eProcess measurement and closed-loop control systems in harsh environments\u003c\/li\u003e\n  \u003cli\u003eApplications requiring mixed analog input and output signals at localized stations\u003c\/li\u003e\n  \u003cli\u003eMachine tool manufacturing, assembly automation, and material handling systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ch4\u003eGeneral\u003c\/h4\u003e\n\u003ctable\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eManufacturer\u003c\/td\u003e\n      \u003ctd\u003eBECKHOFF\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eModel\u003c\/td\u003e\n      \u003ctd\u003eER4374-0002\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eProduct Type\u003c\/td\u003e\n      \u003ctd\u003eEtherCAT Box Combi Module\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eHousing Material\u003c\/td\u003e\n      \u003ctd\u003eZinc die-cast\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eProtection Rating\u003c\/td\u003e\n      \u003ctd\u003eIP65, IP66, IP67 (conforms to EN 60529)\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch4\u003eSignal and I\/O\u003c\/h4\u003e\n\u003ctable\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eNumber of Inputs\u003c\/td\u003e\n      \u003ctd\u003e2 analog inputs\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eNumber of Outputs\u003c\/td\u003e\n      \u003ctd\u003e2 analog outputs\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eSignal Type\u003c\/td\u003e\n      \u003ctd\u003e-10 V to +10 V or 0\/4 mA to 20 mA, parameterizable per channel\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eResolution\u003c\/td\u003e\n      \u003ctd\u003e16 bit\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eLoad (Voltage Output)\u003c\/td\u003e\n      \u003ctd\u003e\u0026gt;
