ProDAQ 6111 Digital Input LXI Instrument

  • Digital Inputs: Each channel of the ProDAQ 6111 has a maximum 24 Volt input level. Each channel is isolated from any other and also from the chassis, with a working isolation voltage up to 300V. This allows any channel not only to float to different voltage potentials but also eliminates the possibility of ground loop error.
  • Various Mounting Options: The ProDAQ 6111 comes in a 1U high unit suitable for rack mount in a standard 19” rack if used with the ProDAQ 5725 Rack-Mount kit. The ProDAQ 6111 can also be desktop mounted using the ProDAQ 5726 Stackable Tabletop Feet Set.
  • 19”, 1U Solution for 256 Digital Input Channels
  • Channel Isolation up to 300 V (input to input, inputs to ground and between inputs, outputs and power supplies)
  • 1kHz Update Rate
  • 5V to 24V Input High Level

Composition and care



The ProDAQ 6111 is an LXI instrument with 256 independent channels, designed to provide an isolated digital interface for up to 256 external sensors. Each channel is isolated from both the chassis and all other channels.
The ProDAQ 6111 provides an easy to use, cost effective and scalable solution for digital input measurement applications. As a standalone LXI instrument it can be directly connected to your network and operated either through the integrated web pages or integrated to your data acquisition application using the VISA-based industry standard plug & play drivers provided. Multiple devices can be synchronized via the IEEE1588 precision time protocol or optional via the LXI trigger bus. The unit is equipped with a redundant power supply and two Ethernet ports.
