Current loop indicator DPM 942-FPSI

LCDLEDpanel-mount

This large current loop indicator features a 3½ digit LCD with 19mm (0.75") digit height and programmable LED backlighting. Calibration is by two multi-turn potentiometers and connection to the current loop is via two screw terminals. The DPM 942-FPSI is a low cost, popular part, normally stocked in high quantity and suitable for new designs. Specification Accuracy (overall error): 0.05 0.1 % (±1 count) Operating temperature: 0 to 50 °C (32 to 122 °F) Sample rate: 3 samples/sec Supply Voltage: 4.5 to 5.5 V d.c. Supply Current: 1 mA FEATURES • 19mm (0.75”) digit height • Dual colour backlight with programmable status indication • Open collector outputs that mirror the backlight status (with inverted output option) • 5V supply voltage • 4–20mA measurement range The DPM 942-FPSI is a 3 ½ digit LCD current loop meter that can also be used for dual colour go-stop status indication. This functionality is ideal for simplifying monitoring applications, where an operator needs to know the status of the equipment at a glance. During standard operation the backlight is green, however if the reading goes beyond 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 colour and outputs can be inverted.
