ES2153

Key Features:

These EtherStax I/O units provide a rugged, highdensity, and high-speed solution to interface a large quantity of analog input signals. Units accept 16 single-ended analog voltage inputs and 16 single-ended current inputs. A DB25 port supports an alternate interface of voltage inputs from 8B signal conditioning modules. This combination of high-density analog current and voltage inputs is ideal for many sensor interface applications in remote zones.

• 32-channel high-density combination of analog current and voltage inputs
• DB25 port for alternate voltage inputs from 8B signal conditioning backpanels
• 3-way isolation and surge suppression
• High-resolution 16-bit A/D
• High-speed scanning for 10 millisecond update of all 32 channels
• Automatic zero/span calibration
• On-demand self-test verifies calibration
• Web browser configuration
• User-configurable sample averaging and integration/totalization function with non-volatile registers
• Dual-format data registers support 16-bit integers or 32-bit floating point
• Scaling registers on all channels
• Peer-to-peer i2o communication with percent-of-span and timed updates
• Operating temperature: -40 to 70°C (-40 to 158°F)
