EVDR7 Multi-I/O Controller and/or Slave Module (EVDR7)
The EVDR7 multi-I/O controller provides precise, repeatable control of one propor-tional 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 multi-input controller is suitable for a wide range of heavy duty industrial, marine, and mobile off-highway equipment applications.
