Each of the six analog output points runs its own signal path with channel-to-channel isolation, so a short on one loop doesn't pull down the other five — critical when you're mixing 4-20 mA transmitters and ±10 V drives on the same card. Resolution runs 16-bit signed binary with three selectable modes: normal mode spans -4096 to 4095, high-resolution mode goes to -12288 to 12287 or -16384 to 16383. The high-resolution mode gives you roughly 0.3 mV per LSB on a ±10 V span — enough for servo valve positioning or load cell trim without an external signal conditioner. Conversion speed is 6 ms per channel. That's 36 ms for a full six-channel update cycle — fast enough for most process loops (temperature, pressure, flow) but not for high-speed motion axes. If you're closing a servo loop at 1 kHz or faster, this module isn't the right fit. ## Power budget and wiring constraints The module draws 0.62 A from the 5 V DC backplane rail. On a fully loaded Q Series rack with multiple analog cards, that 620 mA adds up — check your base unit's 5 V supply capacity before slotting this in. External loop power requires 24 V DC at +20%/-15%, which is standard for industrial 24 V supplies but worth noting if your panel runs a regulated 24 V rail at the tight end. Wiring lands on a 40-pin connector. The mating half is the A6CON4, sold separately. Accepts 0.3 mm² wire (AWG #22) — fine for signal runs inside the cabinet but undersized for long cable pulls over 50 m where voltage drop in the loop becomes a factor. The analog output voltage range is -12 to 12 V DC with an external load resistance of 1 kΩ to 1 MΩ. That bipolar swing covers both unipolar (0-10 V) and bipolar (±10 V) actuator types. If your valve positioner expects 4-20 mA, you'll need an external I/V converter resistor across the output terminals.","metaTitle":"Mitsubishi Q66DA-G Channel Isolated D/A Module, 6 Ch","metaDescription":"Mitsubishi Q66DA-G channel isolated D/A converter module, 6 analog output points, 16-bit signed binary, 6 ms/channel conversion speed.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["PLCs (Programmable Logic Controllers)"],"specifications":{"title":"Q66DA-G","Weight":"0.22","Product No":"Q66DA-G","description":"Channel Isolated Digital-Analog Converter Module","Product type":"Channel Isolated Digital-Analog Converter Module","Digital input":"16-bit signed binary (Normal resolution mode: -4096 to 4095; high resolution mode: -12288 to 12287, -16384 to 16383)","Shipping Weight":"1.3 Kg","lifecycle_stage":"mature","Conversion speed":"6 ms/channel","Estimated Lead Time":"Usually ships in 1-10 working days..","Applicable wire size":"0.3 mm2 (AWG #22)","Analog output Voltage":"-12 to 12 V DC (External load resistance: 1 k to 1 M? )","External supply power":"24 V DC +20%, -15%","Number of I/O occupied points":"16 points (I/O assignment: Intelli 16 points)","Number of analog output points":"6 points (6 channels)","External wiring connection system":"40-pin connector","External device connection connector":"A6CON4 (Sold separately)","Internal current consumption (5 V DC)":"0.62 A","Maximum number of writes for Flash memory":"50,000"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$918.00","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/f303973636f91799d1b169784af80cc6.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the conversion speed of the Q66DA-G?","answer":"6 ms per channel.
