产品描述
The LDPF63000 Display is a versatile display that can increase productivity by offering the plant floor or production area a large visual display of their current status. Whether your measurement is rate or count, the LDPF63000 can satisfy your requirement. These LDPF63000 displays accept various digital inputs through the use of input modules that allow the unit to adapt to most any application. Additional plug-in option cards can add alarms, analog output, and communication/bus capabilities, making the LDPF63000 a truly intelligent panel meter.

Inputs A and B
DIP switch selectable to accept pulses from a variety of sources including switch contacts, TTL outputs, magnetic pickups and all standard sensors.
Logic: Input trigger levels VIL = 1.5V max; VIH = 3.75V min
Current Sinking: Internal 7.8 K pull-up to 12 Vdc, IMAX = 1.9 mA
Current Sourcing: Internal 3.9 K pull-down, 7.3 mA max @ 28 Vdc, VMAX = 30 Vdc
Filter: Damping capacitor provided for switch contact bounce. Limits input frequency to 50 hz and input pulse widths to 10 msec minimum
Magnetic Pickup
Sensitivity: 200 mV peak
Hysteresis: 100 mV
Input Impedance: 3.9 K @ 60 hz
Max Input Voltage: ±40V peak, 30 Vrms
Dual Count Modes: When any dual count mode is used, then user inputs 1 and/or 2 will accept the second signal of each signal pair. The user inputs do not have the Logic/Mag, High/Low Freq, and Sink/Source input setup switches. The user inputs are inherently a logic input with no low frequency filtering. Any mechanical contacts used for these inputs in a dual count mode must be debounced externally. The user input may only be selected for sink/source by the user jumper placement.

Programming Software
(Free download) Allows configuration of the LDPF63000 meter from a PC. This software offers standard drop-down menu commands, that make it easy to program the meter. The unit program can then be saved in a PC file for future use. A serial plug-in card is required to program the meter using the software.
