Product Overview

The 34921A is a Multiplexer Module with 40-channel armature multiplexer with low thermal offset. The multiple multiplexers can connect to the built-in analog buses, allowing scanning up to 560 2-wire channels or 640 1-wire channels in a single mainframe. Also offers 4-channels for directly measuring current. If needed more current channels, shunts can be added to the terminal block for easy current measurements. This multiplexer module features break-before-make connections to ensure that no two signals are connected to each other during a scan. Or, if prefer, can control switching manually to create your own switch configuration. All the multiplexer switches have a relay counter to help predict when relays need to be replaced.

  • <1.5Ω Initial closed channel resistance
  • >10GΩ DC Isolation (ch-ch, ch-earth)
