ELECTRICAL SPECIFICATIONS
Control and Interface Signals:
1. External Speed 0-10V Input
• Input impedance 20k Ohms.
• MIN ON-to-OFF threshold: 190mV*
• MAX OFF-to-ON threshold: 240mV*
• ON (~215mV) to 9.89V linearly scales 1 to 99% speed.
• 9.89V or more deadbands to 100% speed.
2. External LED Output
• 10mA regulated
• LED forward voltages up to 5V
3. RPM Signal
• Signal Value: mVDC = RPM
• Ex: 900mV = 900RPM
• RPM Output Range: ~ 0, 5 to 2000 RPM (0, 5mV to 2000 mV DC)
• RPM Output Resolution: 5RPM (Zero, 400 steps from 5 to 2000 RPM inclusive)
Test Probe JacksPoints:
The test probe jacks may be used to measure the motor rpm or the PWM signal that is being output to the motor.
• In Manual or Analog Control Mode with an Address setting of 1 or greater, the test probe jacks output 0-2000 mVDC representing
motor RPM. By changing the address DIP switches to 0, the test probe jacks will output 0-1000 mVDC representing
0-100% demand signal to the motor. The address may be changed without interrupting power to the control card.
• In Network Control Mode, 0-2000 mVDC always represents RPM.
LED Indicators:
• Onboard Status LED:
The Onboard Status LED is software controlled by the unit microcontroller. The Status LED is solid ON when RPM reported by
the motor is greater than zero and OFF when RPM reported by the motor is zero.
• External Status LED:
Support for an external Status LED (10mA current-controlled driver), via a 2-pin MTA connector, for remote system status notification.
The external Status LED operates in the same manner as the Onboard Status LED.
• Onboard Net LED:
The Onboard Net LED is driven directly by the receive data signal. The NET LED shows all network traffic on a 2-wire network.
The NET LED is intended to confirm low-level network connectivity, independent of microcontroller or firmware functionality. If
A/B network wires are swapped, the NET LED will be normally on, providing quick diagnostics of this common condition.
