Table 38.0 Description of Inputs to AX030210
Input Type
Description
Analog Inputs
Up to 10 analog inputs are available.
0…5VDC or 0…10VDC
4…20mA or 0…20mA
Digital Inputs
Up to 10 digital inputs are available.
The input accepted is active high or active low.
Configurable 10 kΩpullup or pulldown resistor
PWM Signal Inputs
Up to 10 PWM inputs are available to interface to a PWM signal from an ECM, PLC, etc.
PWM Signal Frequency: 0.50 – 10,000 Hz
Amplitude: 5-12V
PWM Duty Cycle: 0 to 100%
Pulse Inputs
Up to 10 pulse inputs are available.
This input counts the number of pulses over the period of the measuring window setpoint and
calculates the frequency of the pulses.
NOTE: The difference between Frequency and Counter mode is that the
Frequency mode measures the number of pulses that occur in the Measuring
Window period and calculates frequency, while the counter gives the period of
time (in milliseconds) it takes for the number of pulses in the Measuring Window
to be read at the input.
16-bit Counter Inputs
Up to ten 16-bit counter inputs are available.
The input is configured to count pulses on the input until the value in the measuring window setpoint is
reached.
Threshold Levels
For digital, PWM, pulse or counter inputs the voltage threshold levels are:
Input positive threshold (signal goes from low to high):
Min. 2.2V, typical 2.9V, max. 3.6V
Input negative threshold (signal goes from high to low):
Min. 1.2V, typical 1.7V, max. 2.3V
Input Accuracy
0-5V: +/- 1%
0-10V: +/- 1%
0-20mA or 4-20 mA: +/- 1%
PWM, single channel: +/- 1%
Frequency/RPM, single channel: +/- 1%
16-bit counter, single channel: +/- 3 mSec (@50 Hz)
Input Resolution
0-5V or 0-10V: 1 mV
0-20mA or 4-20 mA: 1µA
Input Impedance
Voltage 1 MOhm
Current 124Ω
PWM, frequency, 16-bit counter 1 MOhm
Outputs
Analog Outputs
8 Analog outputs
16-bit Digital to Analog
User selectable (0-5V, 0-10V, +/-5V, +/-10V, 0-20 mA, 4-20 mA)
Each analog output can be configured for one of the following options, and the properties and
behavior of the output in each mode is described below in Table 2.0.
Table 2.0 Analog Outputs
0 to 5 Volts
The output is configured to drive a voltage output in the
range of 0V to 5V. If feedback messages are used to
send the output value to the bus, then the message will
be sent with a resolution of 1mV/bit, and a 0mV offset.
-5 to 5 Volts
The output is configured to drive a voltage output in the
range of –5V to 5V. If feedback messages are used to
send the output value to the bus, then the message will
be sent with a resolution of 1mV/bit, and a -5000mV
offset.
0 to 10 Volts
The output is configured to drive a voltage output in the
range of 0V to 10V. If feedback messages are used to
send the output value to the bus, then the message will
be sent with a resolution of 1mV/bit, and a 0mV offset.
-10 to 10 Volts
The output is configured to drive a voltage output in the
range of –10V to 10V. If feedback messages are used
to send the output value to the bus, then the message
will be sent with a resolution of 1mV/bit, and a -
10000mV offset.
0(4) to 20 Milliamps
The output is configured to source a current in the range
of 0(4)mA to 20mA. If feedback messages are used to
send the output value to the bus, then the message will
be sent with a resolution of 1uA/bit, and a 0uA offset.
Compliance voltage is up to 32Vdc.
