This module is specifically engineered to interface with 115 VAC discrete signals, providing reliable sensing for industrial applications such as power generation, petrochemical refining, and heavy-duty manufacturing. By incorporating robust RC filtering, the module effectively mitigates electrical noise, contact bounce, and transient voltage spikes, ensuring consistent and stable data acquisition for the controller.\u003c\/p\u003e\u003ch3\u003eHardware Interface Architecture\u003c\/h3\u003e\u003cp\u003eThe ASB817116 utilizes a sophisticated isolation design to protect the controller backplane from high-voltage field-side transients. Each input path is equipped with optical isolation, creating a physical barrier that prevents ground potential shifts or inductive kickback from impacting internal logic circuitry. The module is designed for direct insertion into standard 800 Series chassis slots, utilizing the parallel data bus for efficient communication of real-time channel status.\u003c\/p\u003e\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\u003ctable border=\"1\"\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eASB817116\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eChannels\u003c\/td\u003e\n\u003ctd\u003e16 Discrete Inputs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Voltage\u003c\/td\u003e\n\u003ctd\u003e115 VAC Nominal (85-130 VAC Range)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFrequency\u003c\/td\u003e\n\u003ctd\u003e47 to 63 Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eON-State Threshold\u003c\/td\u003e\n\u003ctd\u003e85 VAC Minimum\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOFF-State Threshold\u003c\/td\u003e\n\u003ctd\u003e40 VAC Maximum\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Impedance\u003c\/td\u003e\n\u003ctd\u003e12 kOhm at 60 Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIsolation\u003c\/td\u003e\n\u003ctd\u003e1500 VAC (Channel-to-Bus)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBackplane Current\u003c\/td\u003e\n\u003ctd\u003e250 mA at 5 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temperature\u003c\/td\u003e\n\u003ctd\u003e0 to 60 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStorage Temperature\u003c\/td\u003e\n\u003ctd\u003e-40 to 85 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHumidity\u003c\/td\u003e\n\u003ctd\u003e5 to 95% non-condensing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch3\u003eInstallation Guidelines\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eEnsure the chassis backplane power is disconnected before installing or removing the module to prevent electrical damage.\u003c\/li\u003e\n\u003cli\u003eVerify that the field-side voltage matches the 115 VAC rating of the module to avoid hardware failure or safety hazards.\u003c\/li\u003e\n\u003cli\u003eUse shielded cabling for field inputs to minimize EMI interference in high-noise environments.\u003c\/li\u003e\n\u003cli\u003eEnsure proper grounding of the 800 Series chassis to maintain the integrity of the isolation barrier.\u003c\/li\u003e\n\u003cli\u003eAvoid routing high-voltage field lines alongside sensitive low-voltage communication or signal cables.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\u003ch3\u003eWhat is the primary function of the ASB817116 module?\u003c\/h3\u003e\u003cp\u003eThis module is a 16-channel digital input card used to sense 115 VAC signals from field devices like limit switches, proximity sensors, and motor starters within a Modicon 800 Series system.\u003c\/p\u003e\u003ch3\u003eDoes this module provide isolation?\u003c\/h3\u003e\u003cp\u003eYes, the ASB817116 features optical isolation between the field inputs and the controller backplane, providing 1500 VAC dielectric protection to safeguard the internal system logic.\u003c\/p\u003e\u003ch3\u003eWhat are the input voltage requirements?\u003c\/h3\u003e\u003cp\u003eThe module is rated for 115 VAC nominal, with an operating range of 85 to 130 VAC.
