1 igital amplifier module S7 for 1 or 2 proportional solenoids Interface: - analogue - CNopen / J Profibus P - HRT max. 4 analogue differential inputs max. 8 digital inputs Fixed command values djustable via PC (optionally with manual operation on front panel) for snapping on to dome rail also available as controller module (see data sheet ) ERROR FUNCTION SUPPLY USB FIELBUS X4 ESCRIPTION igital amplifier module for installation on dome rail for driving proportional or black/white valves with one or two solenoids. The parameterisation takes place by means of menu-controlled parameterisation- and diagnostics software «PSO» from Wandfluh (USB-interface) or optionally with a manual control on the front panel. Separate ramps for up and down as well as fixed adjustable command values are integrated in the amplifier module as standard. The electronics are optionally available with different field bus interfaces. FUNCTION The amplifier module has one, resp., two Pulse-Width-Modulated current outputs with superimposed dither signal. The solenoid outputs can also be parameterised for black/white solenoids. The analogue and digital inputs as well as the digital outputs can be programmed individually. With this device control tasks can be solved in a very simple manner. The field bus connection enables reading the command value signal as well as the parameterisation directly via the field bus. PPLICTION s snap-on module, the amplifier module is mainly utilised in the industrial field. The module can be mounted on dome-rails. The connection with terminal screws enables commissioning without special tools in a short time. The amplifier module is particularly suitable for applications with additional functions such as ramps, fixed command values, etc. Customerspecific requirements can be implemented in a simple manner.

5 ESIGN The amplifier module can be parameterised by means of the parameterisation software «PSO-S7» through the USB-interface. In addition, the parameterisation software makes a data analysis possible. The software «PSO-S7» is supported by Windows 2000 and Windows XP, Vista and Windows 7 with 32/64-Bit.

21 ESIGN The amplifier module can be parameterised by means of the parameterisation software «PSO-S7» through the USB-interface. In addition, the parameterisation software makes a data analysis possible. The software «PSO-S7» is supported by Windows 2000 and Windows XP, Vista and Windows 7 with 32/64-Bit. Optionally the amplifier module is equipped with a manual control, which enables the setting of the most important parameters by means of rotary selector switch and push-buttons and therefore makes a commissioning of the amplifier module possible without a PC.
