Powered by an integrated 24 VDC power supply, this adapter interfaces up to two FLEX I\/O modules to a Remote I\/O (RIO) network, enabling distributed signal collection and control without dedicated local controllers.\u003c\/p\u003e\n\u003ch3\u003eNetwork Communication and Capacity\u003c\/h3\u003e\n\u003cp\u003eThe adapter translates control messages between the main Remote I\/O scanner and the connected I\/O terminal bases over the Flexbus backplane. Designed specifically for smaller, space-constrained enclosures, it supports a maximum capacity of two I\/O modules while maintaining high-speed real-time signal transmission.\u003c\/p\u003e\n\u003ch3\u003ePower and System Integration\u003c\/h3\u003e\n\u003cp\u003eOperating on 24 VDC, the internal power supply distributes logic power directly across the Flexbus to power the attached module circuits. Its compact modular housing mounts on standard DIN rails, providing an efficient gateway for expanding I\/O nodes in distributed automation architectures.\u003c\/p\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003e1794-ASB2\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eAllen-Bradley (Rockwell Automation)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eFLEX Remote I\/O Adapter\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Voltage\u003c\/td\u003e\n\u003ctd\u003e24 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModule Capacity\u003c\/td\u003e\n\u003ctd\u003e2 I\/O Modules\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMounting Type\u003c\/td\u003e\n\u003ctd\u003eDIN Rail Mount\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.40 lbs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLifecycle Status\u003c\/td\u003e\n\u003ctd\u003eDiscontinued by Manufacturer\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003cp\u003eFrequently Asked Questions\u003c\/p\u003e\n\u003cp\u003eQ: How many FLEX I\/O modules can the 1794-ASB2 adapter support?
