DeltaV M Series Traditional I/O October 2022 www emerson。 Com/deltav 14 AO (Plus) board specification, 16 channels, 4-20 mA, number of HART channels 16 device type 4-20 mA full signal range 1-23 mA accuracy exceeds the range 0.25% resolution 14 bit A/D converter calibration does not require the local bus current (nominal 12V DC) of each board simplex: typical 85 mA, maximum 150 mA. Redundancy: typical 110 mA, maximum 260 mA. When 24V DC (+/- 10%) is isolated, the maximum field circuit power of each card is 400 mA. Each channel is optically isolated from the system and tested at the factory to be 1000V DC.
