7V to 28 VDC powered	10V analog inputs
5V PWM signal output	alternate clamp diodes including fast turn-off
PWM current outputs (average and waveform)	board only version available

applications
- general purpose signal conditioner for industrial control
  - RS-232 to PWM
  - analog to PWM
- engineering development of solenoid based products: valves, actuators, relays
- durability / life cycle testing applications
precision digitally adjustable pulse width modulated square wave output generation, no pot adjustments that drift
operating frequency
- 1 to 1,000 Hz (1 Hz resolution)
- 1,000 to 10,000 Hz (50 Hz resolution)
- 10,000 to 25,000 Hz (100 Hz resolution)
0 to 100 % duty cycle output adjustable in 0.1% step resolution at all frequencies and operational modes
3 output parameter control modes
- manual, using built-in LCD / pushbutton interface
- RS-232 interface
- analog inputs control frequency, duty cycle, or both
low side drive output sinks up to 4A (6A peak)
operates from an external 7 to 28V DC power source
load may be powered by up to a 50V DC source (dual supply configuration)
fuse protected output – uses industry standard mini-ATO fuse
opto-isolated digital input to enable / disable PWM output
signal outputs
- 5V logic-level PWM output
- unfiltered PWM output current (waveform)
- voltage output representing average DC current output
warranty: 90 days for manufacturer defects
Order Number: PWMC-205 (see datasheet for available ordering options)
