B&K Precision DM309 - High Voltage Multiplexer Module

The DM309 8-CH High Voltage Multiplexer with 2 Current Channels increases the maximum measurable voltage from 300 to 600 VDC or 400 Vrms. The 2 additional current channels handle DC and AC measurements up to 2 A without the need of external shunts. For added protection, each current channel connects to a fuse conveniently located within the module. This module supports thermocouple measurements as well, provided there is an external cold junction reference available.
