Digital setpoints are converted into loop current outputs using 16-bit resolution DAC processing per channel. Output refresh timing is aligned with deterministic I\/O update cycles, while channel load is governed by shared module power and backplane current allocation (75 mA class system constraint).\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions (FAQ)\u003c\/h3\u003e\n\u003cp\u003eQ: Does the module support live replacement under load conditions?\u003cbr\u003eA: Yes. RIUP is supported; however, both analog outputs are forced to a zero-current state during module removal and reinitialization of the backplane communication cycle.\u003c\/p\u003e\n\u003cp\u003eQ: Are the two output channels electrically isolated from each other?\u003cbr\u003eA: No. Both channels share a common reference architecture and are not individually isolated.\u003c\/p\u003e\n\u003cp\u003eQ: What happens if output demand exceeds the 20 mA loop range?\u003cbr\u003eA: The output saturates at the configured upper limit (20 mA or scaled range), with no over-range current generation beyond rated DAC limits.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cp\u003eM12 connectors must be fully engaged and locked to maintain IP69K sealing integrity under vibration and washdown conditions. Output loop wiring shall maintain controlled impedance routing and separation from high-frequency switching conductors to prevent noise coupling into 4-20 mA loops. Shield termination must be performed at a single-point ground reference to avoid loop current distortion. During installation or module replacement, ensure output loops are placed in a controlled state to prevent unintended process actuation during backplane resynchronization.\u003c\/p\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":43497705341018,"sku":"1738-OE2CM12","price":123.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0612\/4601\/3530\/files\/1738-OE2CM122.jpg?v=1781508022","url":"https:\/\/www.plcmasters.com\/products\/allen-bradley-1738-oe2cm12-armorpoint-i-o-analog-output-module","provider":"PLC Masters Ltd.","version":"1.0","type":"link"}
