Manufactured by Schneider Electric under the Triconex brand, it serves as the physical and electrical interface baseplate for pulse input modules to process high-speed frequency signals from field instrumentation, such as flowmeters, speed sensors, and event counters.\u003c\/p\u003e\n\u003ch3\u003eSignal Channels and Input Voltage Specifications\u003c\/h3\u003e\n\u003cp\u003eThe baseplate supports 8 pulse input channels designed to accept a variety of signal sources, including square wave pulses, NAMUR sensors, and dry or wet contacts. Input voltage levels range from 5 VDC to 30 VDC, allowing direct connectivity to diverse field transmitter outputs across process safety loops.\u003c\/p\u003e\n\u003ch3\u003eHigh-Speed Frequency Processing\u003c\/h3\u003e\n\u003cp\u003eEngineered for precise speed and flow monitoring, the unit processes standard pulse frequencies up to 10 kHz. Each channel leverages an onboard 24-bit counter to achieve high-resolution pulse accumulation and frequency measurement required for critical control logic.\u003c\/p\u003e\n\u003ch3\u003ePhysical Characteristics and Mounting\u003c\/h3\u003e\n\u003cp\u003eFeaturing a compact footprint, the baseplate measures 2.2 cm x 12.4 cm x 12.6 cm and weighs 0.1 kg. Manufactured in the USA, it mounts into standard Tricon v11 chassis assemblies to route signal paths directly between field wiring and internal system buses.\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\u003e2381 (7400221-100 PI2381)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eTriconex\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003ePulse Input Baseplate\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSystem Platform\u003c\/td\u003e\n\u003ctd\u003eTricon v11 Safety Instrumented System\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNumber of Channels\u003c\/td\u003e\n\u003ctd\u003e8 pulse input channels\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSignal Input Types\u003c\/td\u003e\n\u003ctd\u003eSquare wave, NAMUR sensors, dry\/wet contacts\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Voltage Range\u003c\/td\u003e\n\u003ctd\u003e5 VDC to 30 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFrequency Range\u003c\/td\u003e\n\u003ctd\u003eUp to 10 kHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCounter Resolution\u003c\/td\u003e\n\u003ctd\u003e24-bit counter per channel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e2.2 cm x 12.4 cm x 12.6 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.1 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCountry of Origin\u003c\/td\u003e\n\u003ctd\u003eUSA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What input signal types does the Triconex 2381 baseplate support?\u003c\/p\u003e\n\u003cp\u003eA: It supports square wave signals, NAMUR sensors, and both dry and wet contact pulse inputs across an input voltage range of 5 VDC to 30 VDC.\u003c\/p\u003e\n\u003cp\u003eQ: Which control system platform is compatible with the 7400221-100 baseplate?\u003c\/p\u003e\n\u003cp\u003eA: It is designed specifically for integration within the Triconex Tricon v11 Safety Instrumented System (SIS).\u003c\/p\u003e\n\u003cp\u003eQ: What is the maximum pulse frequency rating for each channel?\u003c\/p\u003e\n\u003cp\u003eA: The baseplate supports a standard frequency range up to 10 kHz with 24-bit counter resolution for pulse accumulation.\u003c\/p\u003e","brand":"Triconex","offers":[{"title":"Default Title","offer_id":67887034990901,"sku":"2381","price":66.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0973\/7630\/5461\/files\/2381_Cocoai.png?v=1792566057","url":"https:\/\/www.5gplc.com\/products\/2381-7400221-100-pulse-input-baseplate-triconex","provider":"High Five PLC Solution Limited","version":"1.0","type":"link"}
