What the Q64DAN does in a Q-series rack
The Q64DAN is a 4-channel digital-to-analog converter module for the Mitsubishi Electric MELSEC-Q series PLC backplane. It converts 16-bit signed binary values from the CPU into analog voltage or current signals on four independent output points. Voltage output spans -10 VDC to +10 VDC into a 1 kΩ to 1 MΩ load; current output covers 0 mA to 20 mA into 0 Ω to 600 Ω. Absolute maximum ratings are ±12 V and 21 mA — exceeding these damages the output stage.
