This module serves as a gateway bridge, enabling seamless data integration between third-party serial devices—such as barcode scanners, weigh scales, flow meters, and VFDs—and an Allen-Bradley control system. By acting as a communication node, it streamlines the connection of proprietary hardware into a centralized backplane, reducing the need for complex external data conversion hardware.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMulti-Vendor Integration:\u003c\/strong\u003e Facilitates communication with diverse serial-based field devices, supporting master\/slave data exchange.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFLEXbus Management:\u003c\/strong\u003e Coordinates I\/O data refreshing for up to 8 adjacent FLEX I\/O modules within the same assembly.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompact Design:\u003c\/strong\u003e Engineered for high-density mounting within standard industrial control panels.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDirect Connectivity:\u003c\/strong\u003e Features an onboard serial connector for point-to-point diagnostic and data character stream acquisition.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eApplications\u003c\/h3\u003e\u003cp\u003eThis module is ideal for material handling, manufacturing, and process automation environments where legacy or specialized serial instrumentation must be integrated into a modern Allen-Bradley FLEX I\/O backplane topology.\u003c\/p\u003e\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\u003ctable border=\"1\"\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003e1794-AV-MVI\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Line\u003c\/td\u003e\n\u003ctd\u003eFLEX I\/O 1794\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModule Type\u003c\/td\u003e\n\u003ctd\u003eSerial Communication Interface\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCapacity\u003c\/td\u003e\n\u003ctd\u003eUp to 8 FLEX I\/O modules\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSupply Voltage\u003c\/td\u003e\n\u003ctd\u003e24 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temperature\u003c\/td\u003e\n\u003ctd\u003e0 to 40 degC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRelative Humidity\u003c\/td\u003e\n\u003ctd\u003e0 to 80 percent (non-condensing)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMounting\u003c\/td\u003e\n\u003ctd\u003e35 mm DIN Rail or Panel Mount\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.34 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch3\u003eInstallation Guidelines\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eESD Precautions:\u003c\/strong\u003e Always use a grounded wrist strap when handling the module to prevent electrostatic discharge damage to internal components.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Requirements:\u003c\/strong\u003e Ensure the 24 VDC power supply is stable and properly fused before connecting the module to the backplane.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e The module is designed for 35 mm DIN rail mounting.
