4 Channel Pulse/Frequency/Quadrature Module – DC Voltage Type (900K01-0201)

The 900K01-0201 4 Channel Pulse/Frequency/Quadrature Module provides three different functionalities: Pulse Input, Frequency Measurement, and Pulse Output. Each of the four channels can be configured for any one of these three functions. A green blinking status LED on the module indicates when the module is being scanned. A red status LED indicates module or channel diagnostics.

Note: Quadrature signal is not supported in the current release.

Item Specification

• Input Voltage Range: 0 VDC to 24 VDC
• Input per Module: 4
• Digital Output Type: Open collector, 5 to 24V, 30mA max, used for fast signaling

Pulse Input Specification

• Input Voltage Range: 0 VDC to 24 VDC
• ON Voltage Level: 3.0 VDC minimum
• OFF Voltage Level: 1.0 VDC maximum
• Input Impedance: 25K ohm
• Frequency: 10 KHz maximum
• Minimum Pulse Width: 3 μsec
• Pulse Counter: 32 bits
• Preset Value: User may configure a preset count value within the range of the 32-bit counter
• Preset Action: Settable as ON or OFF in HC Designer
• Digital Output:
  • If preset action ON, output turns ON for 1 second.
  • If preset action OFF, output latches ON, and remains ON until counter reset command.
• Counting Based on Preset:
  • When the count equals preset value:
    • If preset action ON, counter is reset and immediately resumes count.
    • If preset action OFF, counter is not reset and counts beyond preset value.
• Counter HOLD: When the HOLD input to the pulse input I/O data type is ON in ControlEdge Builder, the counter holds its current value.
• Counter RESET: The counter may be reset only via its I/O data type in ControlEdge Builder, when an OFF to ON transition occurs on the RST input.
• Counter Flags:
  • The OVERFLOW flag (STS=33) gets set when the module counter overflows. This flag can be reset when an OFF to ON transition occurs on RST input.
  • The PREI flag is set when the digital output of the module turns ON.

Frequency Input Specifications

• Input Voltage Range: 0 VDC to 24 VDC
• ON Voltage Level: 3.0 VDC minimum
• OFF Voltage Level: 1.0 VDC maximum
• Input Impedance: 25k ohm
• Frequency: 10 Hz minimum, 100K Hz maximum
• Minimum Pulse Width (frequency ranges):
  • 500 μsec (10 Hz to 500 Hz)
  • 50 μsec (10 Hz to 5 KHz)
  • 2.5 μsec (10 Hz to 100 KHz)
• Digital Output: ON if input frequency is out of range, else OFF

Pulse Output Specifications

• Channels Used: Any one of the channels can be used for Pulse Output. However, using a particular channel for outputting pulses will render the particular input channel unusable for either pulse or frequency input.
• Digital Output Type: Open Collector, 5 to 24V, 30 mA max.
• Frequency Range: 25 Hz – 10KHz
• Duty Cycle: Always 50%
• Pulse Output Duration: Selectable CONTINUOUS or NUMBERED PULSES
