Inputs – Pulse, switch or resistive sensors
Jumper
setting
Description
Contact, Pulse or Resistive (0-50kOhm).
An internal 10k resistor will hold the input to 5V.
This is the factory default setting.
The default input configuration is suitable for connecting passive sensors,
such as a switch, pulse meter or resistor.
With the jumper settings configured to Pulse/resist, (as shown above), the
input has a 10k
Ω
pull-up resistor to +5V, allowing for variable-resistance
devices or switches to be connected directly to the “C” (0 volt) terminal and
one of the four input terminals like this:
If connecting to a pulse meter output, please make sure the polarity matches
the meter's. The C terminal on the ezeio
™
should be connected to the meter's
minus (-) or ground.
Three wire KYZ sensors (Form C) are read as two wire sensors (Form A);
connect K to the ezeio’s C-terminal, and Y to one of the ezeio
™
inputs.
The ezeio
™
input will detect pulses as short as 1ms. Some pulse outputs may
have contact bounce, and requires a special setting in the software to ignore
pulses that are too short. See System Settings.
