The module converts digital safety controller commands into 2 independent 4-20 mA current outputs driving load resistances up to 600 Ω with a typical accuracy of ±0.1% of span. Weighing 0.5 kg (0.8 kg shipping weight) with chassis dimensions of 12.7 x 12.7 x 12.7 cm, the hardware maintains continuous execution across an ambient operating thermal envelope of -40 to +85 deg C.\u003c\/p\u003e\n\u003ch3\u003eHardware 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\u003eFC-TSAO-0220M\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eHoneywell\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eNetherlands\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.5 kg (0.8 kg shipping weight)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e12.7 x 12.7 x 12.7 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temp\u003c\/td\u003e\n\u003ctd\u003e-40 to +85 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003eSafety Manager S300 IOTA bus supply\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eChannel Count\u003c\/td\u003e\n\u003ctd\u003e2 independent analog outputs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Signal\u003c\/td\u003e\n\u003ctd\u003e4-20 mA current loop\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLoad Resistance\u003c\/td\u003e\n\u003ctd\u003e0 to 600 Ω\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAccuracy\u003c\/td\u003e\n\u003ctd\u003e±0.1% of span (typical)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIsolation\u003c\/td\u003e\n\u003ctd\u003eChannel-to-channel and channel-to-bus galvanic isolation\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProtection Rating\u003c\/td\u003e\n\u003ctd\u003eIP20\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSafety Rating\u003c\/td\u003e\n\u003ctd\u003eSIL3 (IEC 61508 compliant)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003e4-20 mA Loop Protocol \u0026amp; Channel-to-Channel Isolation\u003c\/h3\u003e\n\u003cp\u003eThe FC-TSAO-0220M incorporates channel-to-channel and channel-to-bus galvanic isolation barriers engineered for high-integrity 4-20 mA loop protocol circuits. By isolating each analog output drive path from adjacent channels and the internal backplane logic rail, the module prevents ground loop circulating currents and electrical transients from degrading final control element positioning. Integrated hardware diagnostic networks continuously verify field loop impedance, detecting open-circuit wiring faults or unexpected loop load shifts without disturbing controller execution.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What is the maximum load impedance supported per channel on the 4-20 mA output loop?\u003c\/p\u003e\n\u003cp\u003eA: Each individual analog channel supports load resistances from 0 to 600 Ω, permitting direct interface to standard current-to-pressure (I\/P) converters and smart valve positioners.\u003c\/p\u003e\n\u003cp\u003eQ: How does channel-to-channel isolation protect adjacent safety loops during field wiring faults?\u003c\/p\u003e\n\u003cp\u003eA: Galvanic isolation physically separates field current paths, preventing high-voltage transients or ground potential shifts on one loop from interfering with the second output channel or backplane logic.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eMount the FC-TSAO-0220M module onto the corresponding slot on the S300 IOTA termination assembly until the backplane connectors seat completely.\u003c\/li\u003e\n\u003cli\u003eSecure the mechanical retention fasteners to enforce physical locking and ground connectivity to the enclosure frame.\u003c\/li\u003e\n\u003cli\u003eTerminate 4-20 mA field actuator cables to the designated IOTA terminal block, ensuring correct wiring polarity and load resistance under 600 Ω.\u003c\/li\u003e\n\u003cli\u003eConnect individual cable drain shields to the master cabinet grounding bar at a single termination point to prevent noise induction.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Honeywell","offers":[{"title":"Default Title","offer_id":52714118218024,"sku":"FC-SАO-0220М","price":315.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0827\/6266\/2184\/files\/FC-S_O-0220.jpg?v=1790062905","url":"https:\/\/www.powerdcs.com\/ar\/products\/fc-tsao-0220m-safe-analog-output-module-honeywell","provider":"Power DCS Parts Limited","version":"1.0","type":"link"}
