{"product_id":"honeywell-spyder-21-io-pvb6438ns-u","title":"Honeywell Spyder, 21 IO - PVB6438NS\/U","description":"\u003cp\u003eThe Honeywell Spyder 21 IO offers a programmable, standalone controller for variable air volume (VAV) applications with diverse I\/O capabilities, including 6 universal inputs, 4 digital inputs, 3 analog outputs, and 8 digital outputs. Facilitating communication via the BACnet Master-Slave\/Token-Passing (MS\/TP) protocol over RS-485, this controller is capable of EIA-485 network communications with baud rates ranging from 96 to 1152 kbits\/s. \u003c\/p\u003e\n\n\u003cp\u003eThe Spyder 21 IO is equipped with both a real-time clock and a Sylk bus for seamless integration with Sylk-enabled sensors. With support for up to 40 controllers per BACnet MS\/TP segment, this device also includes a function block engine, which empowers designers to program a wide range of HVAC applications. \u003c\/p\u003e\n\n\u003cp\u003eFor enhanced zone control, the controller has a built-in remote wall module interface and scheduler. The integrated Microbridge air flow sensor offers a dual integral restrictor design for specific models, providing easy user access to air flow sensor inputs. \u003c\/p\u003e\n\n\u003cp\u003eCertain actuator models can be directly mounted onto the VAV box damper shaft, offering up to 44 lb-in torque with a 90-degree stroke and 90-second timing at 60Hz. All connections are made to removable terminal blocks, simplifying controller installation and replacement. \u003c\/p\u003e\n\n\u003cp\u003eThe power voltage ranges from 20 to 30 VAC, with an operating temperature between 32 F and 122 F. UL\/cUL listed under UL916 with a plenum rating, the Spyder 21 IO meets FCC Part 15, Subpart B, Class B requirements for radiated emissions. Mounting is facilitated via a DIN rail.\u003c\/p\u003e","brand":"Honeywell","offers":[{"title":"Default Title","offer_id":46474903453932,"sku":"PVB6438NS\/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_51793c1a-d880-401c-b2aa-64afea18399e.jpg?v=1763025988","url":"https:\/\/www.industrialautomationco.com\/products\/honeywell-spyder-21-io-pvb6438ns-u","provider":"Industrial Automation Co.","version":"1.0","type":"link"}
