The Model MLA and MLD field mounted remote indicators receive DC voltage or current signal inputs from electronic Transmitters and indicate process measurement values. They are available with Analog or Digital displays. Both accept 4-20 mA DC input. The remote indicator MLA also accepts 10-50Ma DC and 1-5 VDC. Mounting options are Horizontal or Vertical Pipe mounting, and wall mounting.
Our standard scale for MLA is black background, white numerals and letters, 50 divisions, 0-100%. For MLD, our standard display is 0-100.0%.
Loop powered indicators are commonly used to display process information that is being transmitted to a control room or control system. The display is either analog with pointer and scale or a digital LCD. Their purpose is to provide easy-to-read process values for maintenance or troubleshooting the control system.
