The two additional current channels measure up to 1 A each without the need for external shunts.
Similar to the DM300, the 20 inputs are split into two banks with a switch to make 4-wire measurements. Both 2-wire and 4-wire channels can be mixed on the same module. Features and benefits Scanning speed up to 80 channels per second 2-wire and 4-wire measurements Built-in cold junction reference for thermocouples 300 V maximum input 2 extra channels for direct current measurements up to 1 A each
