Powered by a supply voltage of 100 to 240 VAC (or 24 VAC\/DC), the unit executes process loop control routines across an allowable operating voltage range of 85% to 110%. The controller maintains low power consumption (15 VA max for AC models; 8 W for 24 VDC), transmitting digitized PV\/SV dataset profiles to master PLCs.\u003c\/p\u003e\n\u003ch3\u003ePart Number Code Structure\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eE5EK\u003c\/strong\u003e: Omron 1\/8 DIN digital process controller product family.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAA2\u003c\/strong\u003e: Advanced process control input\/output structure specification.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDRT\u003c\/strong\u003e: Integrated CompoBus\/D (DeviceNet) fieldbus communication module prefix.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTechnical Performance Metrics\u003c\/h3\u003e\n\u003cfigure\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\u003eE5EK-AA2-DRT\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eOmron\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eJapan\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.3 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eShipping Dimensions\u003c\/td\u003e\n\u003ctd\u003e11.35 x 4.8 x 9.6 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temp\u003c\/td\u003e\n\u003ctd\u003e-10 to 55 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003e15 VA (100 to 240 VAC), 12 VA (24 VAC), 8 W (24 VDC)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Supply Voltage\u003c\/td\u003e\n\u003ctd\u003e100 to 240 VAC (50\/60 Hz), 24 VAC\/DC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Voltage Range\u003c\/td\u003e\n\u003ctd\u003e85% to 110% of rated supply voltage\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOverall Dimensions\u003c\/td\u003e\n\u003ctd\u003e4.8 x 11.35 x 9.6 cm (WxLxH)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eShipping Weight\u003c\/td\u003e\n\u003ctd\u003e2 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eFieldbus Bus Communication \u0026amp; Dynamic Scaling\u003c\/h3\u003e\n\u003cp\u003eConnecting directly to DeviceNet trunklines, the controller exchanges cyclic I\/O data with remote masters at fast backplane bus communication velocity.
