CMCP-510 Loop Powered Display for 4-20mA Transmitters

The CMCP-510 loop-powered digital panel meters have a large, easy to read display, and require no external power source. The 9.4 mm digits exhibit uniform intensity over the entire 4-20 mA operating range. Additionally the total maximum loop voltage drop is only 5V.

Both gain (span) and offset (zero) adjustments are performed with on-board precision, 20 turn potentiometers. All decimal-point and range-change selections are made on a six-position DIP switch featuring vibration-resistant, gold-plated contacts. There are no jumpers or solder gaps to close. Connections to the current loop are made via a reliable, two-position, screw-type terminal block.
