The ADN 405 has been developed as a digital servo-amplifier for proportional valves featuring two magnets
The valve output stages function without fast de-excitation
Suitable for simple controlled systems in which the setpoints and ramps are specified digitally
Can be operated with external analog +/–10V signals, or with external 4–20mA or 12mA +/–8mA signals
Digital setpoint application is effected via the CAN bus
The 4–20mA or 12mA +/–8mA input is monitored for wire breakage
Alarms are issued via the separate output
Equipped with five opto-decoupled inputs, other input configurations are also possible
The ramps are assigned to the four internal setpoints and can be set from 0.01s to 30s in increments of 10ms
Can also be actuated externally via an analog input or the CAN bus
All settings on the ADN 405 are made using the ADN configurator via an RS232 interface linked to a PC or laptop computer
