{"product_id":"honeywell-spyder-21-io-pub6438sr-u","title":"Honeywell Spyder, 21 IO - PUB6438SR\/U","description":"\u003cp\u003eThe Honeywell Spyder 21 IO is a versatile, fully programmable unitary controller. Empowered by six User Interfaces, four Digital Inputs, three Analog Outputs, and eight Digital Outputs, it is integrated with BACnet MS\/TP and RS-485. Its Real-Time Clock and Sylk Bus systems are notable features which enhance functionality and usability.\u003c\/p\u003e\n\n\u003cp\u003eThis controller is equipped with an EIA-485 communications network that facilitates Baud rates ranging between 96 and 1152 kbits\/s. Both its controller housing and actuator are UL Plenum Rated, ensuring safety and efficiency. The Spyder supports up to 40 controllers per BACnet MS\/TP segment, although operation under 30 is recommended for optimal performance.\u003c\/p\u003e\n\n\u003cp\u003eIts design accommodates Sylk-Enabled sensors using the Sylk Bus system, characterizing this product as highly adaptable. The unit incorporates a Function Block Engine, allowing application designers tremendous flexibility in HVAC applications. Furthermore, it provides built-in zone control functions such as a remote wall module interface and a scheduler.\u003c\/p\u003e\n\n\u003cp\u003eThe controller is adeptly equipped with a Microbridge air flow sensor featuring a dual integral restrictor design. User access to these sensor inputs is seamless, making this controller user-friendly despite its innovative technological components. Designed with a high-efficiency actuator and removable terminal blocks, the device simplifies both equipment installation and replacement procedures.\u003c\/p\u003e\n\n\u003cp\u003eOperating at a power voltage between 20 to 30 VAC, the Spyder 21 IO performs effectively across an extensive temperature range of -40 F to 150 F. This product is UL\/cUL listed under UL916 with a Plenum rating, and meets FCC Part 15, Subpart B, Class B for radiated emissions requirements. Designed specifically for use in fan coils, heat pumps, and unit heaters, it can be easily mounted using a standard DIN Rail Mount.\u003c\/p\u003e","brand":"Honeywell","offers":[{"title":"Default Title","offer_id":46474904076524,"sku":"PUB6438SR\/U","price":0.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0217\/1112\/6600\/files\/Honeywell_Group_Photo_-_Final_Compressed_a7b341ef-a575-4a0b-9efd-494a98250725.jpg?v=1763026001","url":"https:\/\/www.industrialautomationco.com\/products\/honeywell-spyder-21-io-pub6438sr-u","provider":"Industrial Automation Co.","version":"1.0","type":"link"}
