B&K Precision DM300 - Solid State Multiplexer Module

The DM300 20-CH Solid-State Multiplexer is a general-purpose module with solid state relays for achieving scanning speeds up to 450 channels per second and a maximum input of 120 V. This module provides 20 channels arranged in two 10-CH banks with 2-wire inputs. All channels switch both high and low lines, providing fully isolated inputs for the internal DMM or external instruments. During 4-wire measurements, channels from bank 1 are paired with channels from bank 2 to provide source and sense connections.

Features and benefits

• Scanning speed up to 450 channels per second
• 2-wire and 4-wire measurements
• Built-in cold junction reference for thermocouples
• 120 V maximum input voltage and fully isolated inputs
