The DM301 20-CH Multiplexer with 2 current channels is the most versatile module with armature relays for achieving a maximum input of 300 V and a scanning speed of 80 channels per second. 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.
