This module handles both analog-to-digital and digital-to-analog conversions within a single slot, providing a space-efficient solution for instrumentation tracking and closed-loop process hardware interfaces. It features multiple isolated channels configured to receive and transmit standard industrial current and voltage signals. The unit communicates directly via the CJ-series backplane bus to exchange raw binary data values with the CPU module. It is engineered for industrial processing, temperature modulation, and variable speed drive control across diverse automation infrastructures.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eCombined analog input and analog output functionality in a single-slot module.\u003c\/li\u003e\n\u003cli\u003eSupport for independent configuration of voltage and current signal ranges per channel.\u003c\/li\u003e\n\u003cli\u003eHigh-speed A\/D and D\/A conversion rates synchronized with the backplane processing cycles.\u003c\/li\u003e\n\u003cli\u003eBuilt-in diagnostics including disconnection detection for current input ranges.\u003c\/li\u003e\n\u003cli\u003eDetachable terminal block allows simplified maintenance and pre-wiring tasks.\u003c\/li\u003e\n\u003cli\u003eInternal data scaling and filtering capabilities manageable directly via CPU memory allocation.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eVariable frequency drive speed and torque reference modulation.\u003c\/li\u003e\n\u003cli\u003eTemperature regulation loops in extrusion and packaging machinery.\u003c\/li\u003e\n\u003cli\u003eLevel control and pressure instrumentation reporting in water treatment plants.\u003c\/li\u003e\n\u003cli\u003eProportional valve control and positioning feedback setups.\u003c\/li\u003e\n\u003cli\u003eParameter monitoring in data acquisition and industrial SCADA setups.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ch4\u003eInput\/Output Capacity\u003c\/h4\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"1\"\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd data-row=\"1\"\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"2\"\u003eNumber of Analog Inputs\u003c\/td\u003e\n\u003ctd data-row=\"2\"\u003e4 channels\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"3\"\u003eNumber of Analog Outputs\u003c\/td\u003e\n\u003ctd data-row=\"3\"\u003e2 channels\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"4\"\u003eInput Signal Ranges\u003c\/td\u003e\n\u003ctd data-row=\"4\"\u003e1 to 5 V, 0 to 5 V, 0 to 10 V, -10 to 10 V, 4 to 20 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"5\"\u003eOutput Signal Ranges\u003c\/td\u003e\n\u003ctd data-row=\"5\"\u003e1 to 5 V, 0 to 5 V, 0 to 10 V, -10 to 10 V, 4 to 20 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch4\u003ePerformance and Accuracy\u003c\/h4\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"1\"\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd data-row=\"1\"\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"2\"\u003eResolution\u003c\/td\u003e\n\u003ctd data-row=\"2\"\u003e1\/4000 (standard mode), 1\/8000 (high-resolution mode)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"3\"\u003eConversion Time\u003c\/td\u003e\n\u003ctd data-row=\"3\"\u003e1.0 ms \/ channel max.
