This module enables the direct connection of up to four thermocouples without requiring an additional protective control cabinet. Operating as an expansion node within the Beckhoff Fieldbus Box system, the module communicates via a high-speed, noise-immune IP-Link optical fiber interface connected to an upstream Coupler Box.\u003c\/p\u003e\n\u003cp\u003eEquipped with standard M12 screw-type connectors, the \u003cstrong\u003eBECKHOFF IE3312\u003c\/strong\u003e provides robust 2-wire connections for thermocouple sensors. It supports a broad range of standard thermocouple types and linear millivolt (mV) measurements, offering versatile integration for machine-mount temperature monitoring. The module features internal cold-junction compensation and delivers digitized temperature values directly to the higher-level controller with high resolution and minimal measurement uncertainty.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eFour analog input channels optimized for thermocouple temperature sensors.\u003c\/li\u003e\n  \u003cli\u003eM12 screw-type connection technology providing reliable 2-wire sensor interfacing.\u003c\/li\u003e\n  \u003cli\u003eUniversal sensor compatibility supporting thermocouple types J, K, L, B, E, N, R, S, T, and U, alongside direct mV measurement.\u003c\/li\u003e\n  \u003cli\u003eHigh-speed IP-Link optical fiber ring interface for reliable, noise-immune communication.\u003c\/li\u003e\n  \u003cli\u003eRobust encapsulated housing rated for IP65, IP66, and IP67 environments.\u003c\/li\u003e\n  \u003cli\u003eIntegrated cold-junction compensation for precise temperature readings.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eDecentralized, machine-mount temperature acquisition and process monitoring.\u003c\/li\u003e\n  \u003cli\u003eMulti-channel thermocouple signal collection in harsh and wet industrial environments.\u003c\/li\u003e\n  \u003cli\u003eField-level thermal logging in manufacturing, plastics processing, and material handling systems.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\n    \u003ctr\u003e\n      \u003cth\u003eParameter\u003c\/th\u003e\n      \u003cth\u003eSpecification\u003c\/th\u003e\n    \u003c\/tr\u003e\n  \u003c\/thead\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\u003eIE3312\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eProduct Type\u003c\/td\u003e\n      \u003ctd\u003eFieldbus Box Extension Module (IP-Link)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eNumber of Inputs\u003c\/td\u003e\n      \u003ctd\u003e4 analog inputs (thermocouple)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eConnection Method\u003c\/td\u003e\n      \u003ctd\u003eM12 screw-type, 2-wire connection\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eSupported Sensor Types\u003c\/td\u003e\n      \u003ctd\u003eTypes J, K, L, B, E, N, R, S, T, U, and mV measurement\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eDefault Sensor Setting\u003c\/td\u003e\n      \u003ctd\u003eType K\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eMeasuring Range\u003c\/td\u003e\n      \u003ctd\u003eSensor-dependent (Preset Type K: -100 to +1370 Celsius)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eResolution\u003c\/td\u003e\n      \u003ctd\u003e0.1 Celsius per digit\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eMeasurement Uncertainty\u003c\/td\u003e\n      \u003ctd\u003eLess than +\/- 0.5% (relative to full-scale value)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eConversion Time\u003c\/td\u003e\n      \u003ctd\u003eApproximately 250 ms (configurable down to 70 ms)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eInput Filter\u003c\/td\u003e\n      \u003ctd\u003e5 configurable variations\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eNominal Voltage\u003c\/td\u003e\n      \u003ctd\u003e24 V DC (-15% \/ +20%)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eCurrent Consumption (from US)\u003c\/td\u003e\n      \u003ctd\u003e40 mA (excluding sensor current)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003ePower Supply Connection\u003c\/td\u003e\n      \u003ctd\u003eFeed: 1 x M8 male connector, 4-pin;
