Engineered for direct installation in the field, this module bypasses the need for a protective control cabinet, significantly reducing wiring overhead and simplifying system architecture.\u003c\/p\u003e\n\u003cp\u003eWith 8 digital output channels, the BECKHOFF IP2021-B318 delivers up to 2 A per channel at 24 V DC. This high current-carrying capacity makes the device highly suited for driving medium-power loads such as hydraulic and pneumatic solenoids, contactors, indicators, and smaller actuators.\u003c\/p\u003e\n\u003cp\u003eThe module is constructed for deployment in demanding industrial environments, featuring an IP67 physical protection rating. It utilizes secure M8 screw connectors for signal I\/O and features an integrated PROFIBUS T-connector to facilitate straightforward bus daisy-chaining and clean physical cable routing.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e8 digital output channels with a nominal voltage of 24 V DC\u003c\/li\u003e\n  \u003cli\u003eSupports load currents up to 2 A per channel\u003c\/li\u003e\n  \u003cli\u003eShort-circuit protected output architecture\u003c\/li\u003e\n  \u003cli\u003ePROFIBUS DP fieldbus communication interface\u003c\/li\u003e\n  \u003cli\u003eIntegrated T-connector for simplified PROFIBUS wiring topologies\u003c\/li\u003e\n  \u003cli\u003eM8 connector system for all local I\/O connections\u003c\/li\u003e\n  \u003cli\u003eIP67-rated enclosure for cabinet-free installation directly on machinery\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eDecentralized control of solenoids, contactors, and actuators\u003c\/li\u003e\n  \u003cli\u003eConveyor and material handling automation in harsh environments\u003c\/li\u003e\n  \u003cli\u003ePneumatic valve terminal integration\u003c\/li\u003e\n  \u003cli\u003eMachine tool and assembly line fieldbus distribution\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\u003eIP2021-B318\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eProduct Type\u003c\/td\u003e\n      \u003ctd\u003eFieldbus Box\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eProtocol\u003c\/td\u003e\n      \u003ctd\u003ePROFIBUS DP\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eNumber of Outputs\u003c\/td\u003e\n      \u003ctd\u003e8 digital outputs\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\u003eMaximum Output Current\u003c\/td\u003e\n      \u003ctd\u003e2.0 A per channel (short-circuit proof)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eI\/O Connection Method\u003c\/td\u003e\n      \u003ctd\u003eM8 screw type\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eBus Connection\u003c\/td\u003e\n      \u003ctd\u003eIntegrated T-connector\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eProtection Class\u003c\/td\u003e\n      \u003ctd\u003eIP67\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eOperating Temperature\u003c\/td\u003e\n      \u003ctd\u003e0 degC to +55 degC\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eStorage Temperature\u003c\/td\u003e\n      \u003ctd\u003e-25 degC to +85 degC\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eInstallation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n  \u003cli\u003eVerify that the module model (IP2021-B318) matches your system configuration and design drawings.\u003c\/li\u003e\n  \u003cli\u003eIsolate all electrical power sources (both system logic power and field sensor\/actuator power) before installation.\u003c\/li\u003e\n  \u003cli\u003eMount the Fieldbus Box securely to a flat machine surface using the designated mounting holes.\u003c\/li\u003e\n  \u003cli\u003eConnect the PROFIBUS network lines to the integrated T-connector.
