Product description
Set-up
The directional control valve with IAC Multi Ethernet electronics mainly consists of:
- Direct operated directional control valve (1) with control spool and sleeve in servo quality
- Integrated digital axis controller (2) with:
- analog/digital interface (XH2)
- Ethernet interfaces (X7E1, X7E2)
- analog sensor interfaces (X2M1, X2M2)
- digital sensor interface (X8M)
- Integrated digital axis controller (2) with:
Directional control valve with integrated axis controller, analog interfaces (X2M1, X2M2), digital interfaces (XH2, X8M) and Ethernet interfaces (X7E1, X7E2)
Functional description
The IAC Multi Ethernet valve (Integrated Axis Controller based on directional control valves) is a digital directional control valve with integrated axis controller and the following functionalities:
- Position control
- Pressure/force control
- Closed-loop speed control
- Substitutional closed-loop control (position - pressure/force)
- Substitutional control (flow - pressure/force)
- pQ function (flow-controlled)
This enables, amongst others, the following operating modes:
- Valve direct control
- Drive-controlled position control
- Drive-controlled positioning
- Positioning block operation
- The command values are preset via the Ethernet interface (X7E1 or X7E2) or, alternatively, via the analog/digital interface (XH2)
- The feedback information of the actual value signals to the superior control system is provided optionally either via the Ethernet interface (X7E1 or X7E2) or the analog/digital interface (XH2)
- The controller parameters are set via the Ethernet interface (X7E1 or X7E2)
Monitoring
The digital control electronics enable comprehensive monitoring functions/error detection including:
- Undervoltage
- Communication error
- Cable break for analog sensor inputs and digital position measurement system
- Short-circuit monitoring for analog/digital outputs
- Monitoring of the microcontroller (watchdog)
- Temperature of the integrated electronics

- PC operating systems: Windows XP (SP3), Windows 7
Safety function
The integrated control electronics of the valve enables the additional shut-off of a channel according to EN 13849-1 in the direction P to A (depending on the application, the fail-safe position must be adhered to).
For this purpose, a suitable control system must be provided to perform the plausibility check between the direction-dependent valve signals "enable input" and "enable acknowledgement" (signal fed back by the valve).
It is not possible to switch off direction P to B in a safety-relevant manner according to EN 13849-1 (depending on valve type).
