Digital to 4-to-20 mA for Process Control

Loop DACs Ease the Transition to Direct Digital Control; 10-Bit DAC1422 Protects Process if Computer Goes Down

Models DAC1420/1422 are 8/10-bit d/a converters with analog output in the form of a 4-to-20mA current source. Specifically designed for the process-control industry, and requiring but a single +10V to +36V power supply, they meet the requirements of ISA standard S50.1 for Type 3 Class U (3-wire non-isolated) output.
