This module provides reliable relay contact switching capabilities, making it well-suited for low-voltage and low-power control schemes where circuit isolation and signal flexibility are required. The 1771-OYC incorporates mechanical relay outputs that isolate connected field devices from internal backplane logic, helping to protect sensitive control infrastructure from line transients and faults originating on external power circuits.\u003c\/p\u003e\n\u003cp\u003eEngineered for industrial environments utilizing the 1771 I\/O platform, this module accommodates a range of AC and DC signal types. It includes the standard 1771-WN wiring arm to facilitate secure field wiring terminations and straightforward installation or replacement procedures within an existing rack layout. Note that this specific module utilizes mercury-wetted contact technology for enhanced switching performance, which requires appropriate handling and disposal procedures in accordance with local environmental regulations.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eCompatible with standard Allen-Bradley 1771 I\/O chassis and PLC-5 programmable controller systems.\u003c\/li\u003e\n  \u003cli\u003eProvides electrical isolation between field output devices and backplane logic to safeguard against line transients.\u003c\/li\u003e\n  \u003cli\u003eSupports flexible application voltages across both AC and DC switching loops.\u003c\/li\u003e\n  \u003cli\u003eIncludes the 1771-WN wiring arm for organized and efficient field wiring connections.\u003c\/li\u003e\n  \u003cli\u003eUtilizes mercury-wetted relay contacts for consistent low-level signal switching.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eLow-voltage and low-power industrial control logic\u003c\/li\u003e\n  \u003cli\u003eDiscrete actuator and indicator interfacing\u003c\/li\u003e\n  \u003cli\u003eLegacy PLC-5 system expansions and maintenance replacements\u003c\/li\u003e\n  \u003cli\u003eSignal switching requiring galvanic isolation between independent circuits\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\u003eAllen-Bradley \/ Rockwell Automation\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eExact Model\u003c\/td\u003e\n      \u003ctd\u003e1771-OYC\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eProduct Type\u003c\/td\u003e\n      \u003ctd\u003ePLC-5 Contact Output Module\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eProduct Family\u003c\/td\u003e\n      \u003ctd\u003e1771 Universal I\/O \/ PLC-5\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eOperating Voltage (AC)\u003c\/td\u003e\n      \u003ctd\u003e0 to 250V AC\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eOperating Voltage (DC)\u003c\/td\u003e\n      \u003ctd\u003e0 to 175V DC\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eMax Voltage \/ VA Ratings\u003c\/td\u003e\n      \u003ctd\u003e30VA at 138V AC; 20VA at 125V DC\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eMax Continuous Current\u003c\/td\u003e\n      \u003ctd\u003e2 Amps at 100V AC (200VA max) per module\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eBackplane Current Draw\u003c\/td\u003e\n      \u003ctd\u003e550 mA\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eSignal Delay (OFF)\u003c\/td\u003e\n      \u003ctd\u003eAC: 45 ms (+\/-15 ms); DC: 50 ms\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eIncluded Accessories\u003c\/td\u003e\n      \u003ctd\u003e1771-WN Wiring Arm\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eCountry of Origin\u003c\/td\u003e\n      \u003ctd\u003eUnited States\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eConnections \/ Interfaces\u003c\/h3\u003e\n\u003cp\u003eThe 1771-OYC module interfaces with the PLC-5 system via the standard 1771 I\/O backplane connector, which supplies necessary operating power and communication pathways to the processor.
