Panel Tachometer

---

Great versatility with multiple sensor input capability in one unit: NPN open collector, contact and square or sine wave sensor inputs

---

With its industry-leading 0.87” (22 mm) height display and compact body depth of only 3.6" (92 mm), the Checkline DT-501X allows mounting in tight panels or small enclosures. Added versatility is offered with its range of standard inputs which include NPN, contact and square or sine wave signals produced from devices such as pulse generators, proximity sensors, photoelectric sensors, magnetic sensors, rotary encoders and NPN OC transistors. The Checkline DT-501X is fully scalable and possesses four selectable modes allowing it to measure various process speeds, rates and times: tachometer, flowmeter, process time span and elapsed time mode which displays the inverse to the input signal, common in oven conveyor applications. An added teaching function auto-scales the control which simplifies the set-up by properly coordinating the display with the input of the sensor’s signal. Analog, contact, or SSR outputs are available for additional automation control. 

These enhanced features of the DT-501X Panel Meter makes them the perfect choice for speed, process rate or time applications such as machining operation timing, conveyor speed, motor output, volumetric flowrate, elapsed time of oven curing etc.

Features

• Industry-leading 0.87" (22 mm) height, 6 digit, red LED display enables viewing from greater distances
• Integral sensor power source saves money by eliminating need to purchase a separate power supply
• Scalable programming gives user the flexibility to set up and monitor virtually any process
