Electronic control unit ASCO

Features:

• Converts the analog control signal to valve coil current
• Off function, when the control is less than 2% of the maximum control
• The output current to the coil is independent of the coil resistance (temperature) and the supply voltage variation
• Minimum and maximum current to the coil can be adjusted according to the control message
• Electronics integrated in housing with connector for ISO 4400 or DIN 46244 plug
