Bosch Rexroth’s IAC Multi-Ethernet control valve, with integrated axis controller, allows for the regulation of intelligent hydraulic drives in real time, regardless of the overall machine control system. In addition, the control valve software automatically takes into account the specific characteristics of the fluid technology used in the system. Through Safety on Board, the control valve meets decentralized safety requirements up to category 4/PL e according to ISO 13849. The control electronics enable the standard-compliant switching of a channel from P to A. With the removal of the analog 24V signal to the enable input, the output stage and the valve magnet are separated internally from the adjacent supply voltage. The enabling acknowledgment only occurs after reaching the safe valve control slide position.
