As part of the modular ControlLogix architecture, this unit features 16 normally open, individually isolated relay output points capable of handling flexible voltage ranges from 5 to 125VDC and 10 to 240VAC. The module supports scheduled outputs and configurable fault states including Hold Last State, User-Defined On, and User-Defined Off, providing robust control state management during controller communication faults or system transitions.\u003c\/p\u003e\n\u003cp\u003eEngineered for demanding industrial environments, the 1756-OW16I mounts directly into any ControlLogix chassis and interfaces with field wiring via a removable terminal block (RTB). The isolated channel architecture allows multiple power sources and differing voltage potentials to be switched across the same physical module without cross-circuit interference. Backplane power is efficiently managed, drawing 150mA from the 5.1VDC and 24VDC rails, while robust mechanical relays ensure reliable isolation between high-power field devices and low-voltage controller backplanes.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e16 individually isolated dry contact relay output points for multi-voltage flexibility\u003c\/li\u003e\n  \u003cli\u003eWide operating voltage range supporting 5 to 125VDC and 10 to 240VAC\u003c\/li\u003e\n  \u003cli\u003eConfigurable fault-mode behavior including Hold Last State and default Off-state options\u003c\/li\u003e\n  \u003cli\u003eSupports scheduled output execution synchronized with system time\u003c\/li\u003e\n  \u003cli\u003eCompatible with standard ControlLogix 1756 removable terminal blocks (RTBs)\u003c\/li\u003e\n  \u003cli\u003eC300 and R150 pilot duty ratings for inductive load handling\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eSwitching mixed AC and DC actuator loads within a single chassis slot\u003c\/li\u003e\n  \u003cli\u003eInterfacing controller logic with high-current motor starters and solenoids\u003c\/li\u003e\n  \u003cli\u003eIsolating control system outputs from hazardous or noisy field power supplies\u003c\/li\u003e\n  \u003cli\u003eManaging safety-interlock relay chains and alarm annunciation circuits\u003c\/li\u003e\n  \u003cli\u003eExecuting scheduled discrete control actions in continuous process automation\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\u003eTechnical Parameter\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\u003eModule Type\u003c\/td\u003e\n      \u003ctd\u003eIsolated Relay Contact Output Module\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eNumber of Outputs\u003c\/td\u003e\n      \u003ctd\u003e16 normally open, isolated points\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eOperating Voltage Range\u003c\/td\u003e\n      \u003ctd\u003e5 to 125VDC, 10 to 240VAC\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eCurrent Rating per Point\u003c\/td\u003e\n      \u003ctd\u003e1A at 5 to 30VDC;
