Input Sensor Wiring
The Series 3100 is a Dual Channel unit . Either a single input, or any combination of two Pulse or Analog inputs can be used .
The pulse inputs are extremely versatile, designed to accept either two-wire (Data Industrial 200 Series), three-wire pulse
inputs (4000 series) or zero-crossing sine wave inputs (turbines with a magnetic coil pick-up) .
The analog inputs can accept 0…20 mA, 4…20 mA, 0…1V DC, 0…5V DC, or 0…10V DC . Both the top and bottom ends of the
analog range can be configured in the field so that most inputs can be accepted if the hardware limitations are not exceeded .
Contact the factory for assistance with custom inputs . Although different rear panel terminals are used, all parameters are set
with the LCD/keypad interface . No internal or external jumpers, switches or potentiometers require movement or adjustment .
Pulse Inputs (Solid State Switch or Sine Wave)
Four types of pulse input types are accommodated .
• Pulse-DI: Used for all Data Industrial Flow Sensors . Provides an internal pull-up resistor and uses “K” and “Offset” values for
calibration .
• Pulse –K Factor: Accepts non Zero Crossing inputs but provides no internal pull-up, classical “K” (pulses/gal) values for
calibration .
• Pull-up K Factor: Provides an internal pull-up resistor and uses classical “K” ( pulses/gal) values for calibration .
• Sine-K Factor: Accepts zero crossing low voltage sourcing devices, with classical “K” ( pulses/gal) calibration .
