EVDR7 Controller

 

FEATURES:
Microprocessor based control (standard software or OEM software on request)..
Standard hardware and software adapts to many applications.
Independent outputs for four proportional
valves (0 to 2A) and 1 on/off valve (2 A).
• Up to four universal analog or digital inputs: voltage, current, resistive, PWM, frequency, or digital.
Digital input (one) for interface to switch, etc.
• Priority control sensor, selectable.
Robust 8 to 60 VDC power supply interface
with reverse polarity protection.
Four, +5V reference voltage-to-power input devices (100mA with output to common ground).
Thermal overload and overvoltage protection provided.
Rugged IP67-rated packaging with
IP69K-rated plug-in connections.
Operational from -40 to 85°C
(-40 to 185°F).
CAN for networking capability, user configuration and diagnostics.
  DESCRIPTION

The EVDR7 multi-I/O controller provides precise, repeatable control of one proportional solenoid valve coil and one on/off solenoid valve coil. Controller input signals can be resistive temperature sensor, frequency, PWM, digital, voltage, or current.

Analog inputs and multiple switched inputs are optional to suit a range of machine applications. The CAN J1939 communications port, along with the USB-to-CAN adapter, allows the EVDR7 setup parameters to be configured using a PC. Also, the CAN port can be set up to provide communications with other devices on the network.

This versatile, multi-function controller is suitable for a wide range of heavy duty industrial, marine, and mobile off-highway equipment applications.

To ground a PWM input use an
analog GND connection pin.

Active high digital inputs can be
connected to the +5V reference.

Active low inputs can be grounded
to the analog GND connection pin.
