Designed to switch DC field loads, it supplies 24 V DC at up to 0.5 A per channel using optocoupler-isolated transistor outputs. The module organizes its 32 channels into four isolated groups of eight outputs and requires a single 40-pin front connector for field wiring.\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\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\u003e6ES7322-1BL00-0AA0\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eSiemens\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Series\u003c\/td\u003e\n\u003ctd\u003eSIMATIC S7-300\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eDigital Output Module\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNumber of Digital Outputs\u003c\/td\u003e\n\u003ctd\u003e32\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Type\u003c\/td\u003e\n\u003ctd\u003eTransistor (sinking\/sourcing per 24 V DC load requirements)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRated Output Voltage\u003c\/td\u003e\n\u003ctd\u003e24 V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePermissible Voltage Range\u003c\/td\u003e\n\u003ctd\u003e20.4 to 28.8 V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRated Output Current\u003c\/td\u003e\n\u003ctd\u003e0.5 A per channel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum Output Current\u003c\/td\u003e\n\u003ctd\u003e0.6 A per channel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum Current per Group\u003c\/td\u003e\n\u003ctd\u003e4 A (across 8 channels)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum Total Current\u003c\/td\u003e\n\u003ctd\u003e16 A per module\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNumber of Output Groups\u003c\/td\u003e\n\u003ctd\u003e4\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eShort-Circuit Protection\u003c\/td\u003e\n\u003ctd\u003eIntegrated electronic protection (typical response threshold 1 A)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInductive Voltage Limitation\u003c\/td\u003e\n\u003ctd\u003eLimited to L+ (-53 V)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGalvanic Isolation\u003c\/td\u003e\n\u003ctd\u003eOptocoupler (500 V DC test voltage between groups and backplane)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSwitching Frequency\u003c\/td\u003e\n\u003ctd\u003e100 Hz (resistive load), 0.5 Hz (inductive load), 10 Hz (lamp load)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum Lamp Load\u003c\/td\u003e\n\u003ctd\u003e5 W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Switching Delay\u003c\/td\u003e\n\u003ctd\u003e100 us (0 to 1), 500 us (1 to 0)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBackplane Bus Current\u003c\/td\u003e\n\u003ctd\u003e110 mA at 5 V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTypical Power Dissipation\u003c\/td\u003e\n\u003ctd\u003e6.6 W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFront Connector\u003c\/td\u003e\n\u003ctd\u003e1x 40-pin\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum Cable Length\u003c\/td\u003e\n\u003ctd\u003e1000 m (shielded), 600 m (unshielded)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProtection Class\u003c\/td\u003e\n\u003ctd\u003eIP20\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions (W x H x D)\u003c\/td\u003e\n\u003ctd\u003e40 mm x 125 mm x 120 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNet Weight\u003c\/td\u003e\n\u003ctd\u003e0.26 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eChannel Load Capabilities and Signal Timing\u003c\/h3\u003e\n\u003cp\u003eEach of the 32 transistor channels switches up to 0.5 A at 24 V DC under continuous operation.

A: No, it requires a separate 40-pin removable front connector block to terminate the field wiring.\u003c\/p\u003e\n\u003cp\u003eQ: How is short-circuit protection handled on individual output channels? A: The module incorporates electronic short-circuit protection for each channel, with a typical trip threshold around 1 A.\u003c\/p\u003e\n\u003cp\u003eQ: What is the maximum permitted load current for a single output group? A: Each 8-channel group supports up to 4 A total current, subject to an overall module limit of 16 A.\u003c\/p\u003e","brand":"Siemens","offers":[{"title":"Default Title","offer_id":67894693232739,"sku":"6ES7322-1BL00-0AA0","price":190.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0583\/5246\/8067\/files\/257._996a02fa-7c4d-4ca3-ab2e-31992c0a2b6e.jpg?v=1794193036","url":"https:\/\/www.autocontrolglobal.com\/products\/siemens-6es7322-1bl00-0aa0-simatic-s7-300-digital-output-module","provider":"AutoControl Global","version":"1.0","type":"link"}
