The A-626 and A-628 are 12-bit analog output boards with 16 channels of digital input and 16 channels of digital output. The A-626 and A-628 boards support both current and voltage range. The output channel can be jumper selectable for different voltage ranged: ±10V, ±5V, 0-5V, and 0-10V and can sink 4-20mA current when connected to an external voltage source. On board reference chip BB Ref-01 is used for solving the thermo-drifting problem of the reference voltage. A-626 is much better than 726 families for long periods of operation. Lattice FPGA on board increases the stability of the board.

Power Requirements

NOTE:
The A-626 & A-628 provide current loop. The user should need a external power supply to provide a bias voltage for FET. Please refer to the right hand side figure.
