This decentralized I\/O device is part of the Fieldbus Box series, which enables direct mounting on machinery without the need for a protective control cabinet, reducing cabling efforts and installation footprint.\u003c\/p\u003e\n\u003cp\u003eThis module features eight digital outputs rated for 24 V DC nominal voltage. Each channel supports a continuous load current of up to 2 A, making it highly suitable for driving ohmic, inductive, and lamp loads. To ensure system reliability and protection against field-side faults, all outputs are individually short-circuit proof.\u003c\/p\u003e\n\u003cp\u003eHoused in a compact and durable polyamide enclosure, the \u003cstrong\u003eBECKHOFF IP2042-B730\u003c\/strong\u003e offers high environmental ingress protection (IP65\/66\/67). It communicates via Modbus RTU or ASCII protocols over an RS485 physical layer, supporting adjustable data transfer rates up to 38,400 baud. Setup is easily accomplished using built-in address selection switches or the KS2000 configuration software.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eEight 24 V DC digital outputs in a decentralized, cabinet-free form factor.\u003c\/li\u003e\n  \u003cli\u003eUp to 2 A switching current per channel with individual short-circuit protection.\u003c\/li\u003e\n  \u003cli\u003eDirect Modbus RTU\/ASCII communication over RS485.\u003c\/li\u003e\n  \u003cli\u003eRobust polyamide PA6 housing certified for IP65, IP66, and IP67 protection ratings.\u003c\/li\u003e\n  \u003cli\u003eM12 connection technology for field devices and bus interfacing.\u003c\/li\u003e\n  \u003cli\u003eOnboard address selection switches for convenient node configuration.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eDistributed digital actuator control in decentralized industrial automation setups.\u003c\/li\u003e\n  \u003cli\u003eDirect connection of high-current loads such as solenoid valves, contactors, and signaling equipment.\u003c\/li\u003e\n  \u003cli\u003eOn-machine installation in harsh environments prone to dust, moisture, and vibration.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\n\u003ch4\u003eGeneral\u003c\/h4\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\u003eIP2042-B730\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eProduct Type\u003c\/td\u003e\n      \u003ctd\u003eFieldbus Box (Digital Output)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eHousing Material\u003c\/td\u003e\n      \u003ctd\u003ePA6 (polyamide)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eConfiguration Options\u003c\/td\u003e\n      \u003ctd\u003eAddress selection switch or KS2000 software\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch4\u003eDigital Outputs\u003c\/h4\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\u003eNumber of Outputs\u003c\/td\u003e\n      \u003ctd\u003e8\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eOutput Connections\u003c\/td\u003e\n      \u003ctd\u003eM12, screw-type\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eLoad Type\u003c\/td\u003e\n      \u003ctd\u003eOhmic, inductive, lamp load\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eNominal Output Voltage\u003c\/td\u003e\n      \u003ctd\u003e24 V DC (-15% \/ +20%)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eMax.
