DPM 942-FPSI产品概述
The DPM 950S-FPSI (31/2-digit LCD voltmeter) and DPM 942-FPSI (4-20 mA loop powered meter) can also be used as dual color go-stop displays. During standard operation the backlight is green, however as readings move outside of the user programmable thresholds, the display will turn red. Three open collector outputs are included that indicate high, OK and low conditions. Both the backlight color and outputs can be inverted independently. Module setup is a simple operation, using an 8-way DIP switch and two push buttons. No special tools or equipment are required.
