The Model 900R Modular Solenoid Controller is a rugged, cost effective control module that is designed for interfacing high-performance solenoid actuators (such as Acro's Model 951, 955 and 958 solenoid pinch valves) to computer systems and digital logic. Its primary purpose is to provide Pulse & Hold actuation, which increases the performance of solenoid valves by optimizing power consumption and minimizing heat generation.

Standard Features

• Pulse Width Modulation (PWM) Mode conserves energy and reduces waste-heat production.
  
  
• High Output Drive: 5.0 Amps.
  
  
• Integrated Current Sensor analyzes load current for additional power savings, making it 3 to 10 times more power efficient.
  
  
• Opto-Isolated Differential Trigger (user interface) and can be directly wired to relays, transistor logic, digital I/O boards and PLCs.
  
  
• Protection against short-circuits, power reversal on its supply pins, and over/under current conditions.
  
  
• Multi-Color Diagnostic LED for easy configuration and diagnosis.
