Pulse Width Modulator Control Module

Suitable for customized or specialized control of:

• hydraulic valves
• servomotors
• electrochemical processes

Provides:

• Bipolar or monopolar PWM output.
• Motor speed and direction control.
• Process signal to current and/or power.

Specifications:

Output:   

• Bipolar up to ±26 V up to 2 A, suited to ±12 V and ±24 V systems.
• Constant current or voltage control.
• Four quadrant control - DC to 5 kHz.
• Pulse width control from 0 to 100% with resolution of 0.5%.
• Output frequency control from 0 to 5 kHz with resolution 1 Hz.
• Output bridge voltage control from 6 to 26 V.

Protection: 

• Digital temperature sensor located close to output power FETs.

Power In:  

• DC in 20 to 30 VDC or AC in 15 to 25 VAC.

LEDs:   

• 10 segment bi-colour LED bargraph for display of any parameter.
• Three display LEDs on top side with same surface mount LEDs to display LED status on component side.

    
  Analogue Inputs: 

• Two analogue inputs (non-isolated) with signal conditioning to accommodate current inputs from 0 to 100 mA (input resistance 100Ω) and voltage inputs 0 to 100 VDC (input resistance >100 kΩ).
• Standard inputs are: 0-20 mA, 4-20 mA, 0-10 V.

Digital Inputs: 

• One push button input.
• One jumper input.
• One digital input which can also be configured as a digital output.
• Two digital inputs: 0-5 V, 0-12 V or 0-24 V.

Selector Switches: 

• Three 10 position rotary switches for parameter selection or programming.

Relay Output: 

• One relay output, NO, NC and COM connections provided.
• Rated at 30 V DC at 0.5 A or 110 VAC at 0.5 A.

Clock: 

• Real time clock for any timekeeping functions.
• Requires external battery power for clock operation when unit is not powered.
