SWP-99 Multi-channel Process Indicator

Quick Overview

The SWP-99 Multi-channel Process indicator is designed to measure and display up to 0/4-20mA inputs. The LCD allows up to 8 channels to be displayed at any one time and also the trend of any channel for the preceeding 12 or 90 seconds. The device is equipped with 2, 4 or 8 current inputs and 2 electronic relay outputs.
View Options


The SWP-99 indicator is intended for measuring and  presentation of current values from 8 measuring channels. Each channel can be individually designated (described) with any measuring unit. The LCD graphical display allows for visualization of the values from all 8 channels simultaneously. A significant advantage is the possibility of viewing the trends in each measuring channel as the graphs for the last 12 or about 90 seconds. Each device is equipped with electronic relay outputs that can be used to control external devices. There are icons on the screen signalling the status of the outputs


  • Programmable measuring range.
  • Simultaneous display of values from up to 8 measuring channels
  • Viewing the trends in each of up to 8 measuring channels
  • Any text description possible: name and units
  • Data transfer to the master system via RS-485
  • Password protected
  • Programmable indication filtration.
