The Moog Buffer Amplifier interfaces between standard PLCanalogue input and output modules, on one side, and aposition transducer and a Moog valve, on the other.lt simplifies the use of a PLC in closing position loops.The Buffer Amplifier solves the common problem of the :10VPLC output being incompatible with the valve driverequirements.
Digital noise from the PLC 10V output is filtered with a switchselectable first order filter and converted to two switch selectableoutputs. The first is 10V and the second is a switch selectablecurrent output of : 5mA to :100 mA. This allows for most Moogelectrical feedback (efb) and mechanical feedback (mfb) valves.

The filter and valve current selector switches can have more thanone of each selected, so the selected values are summed. forexample, selecting 50 and 30 mA together will give a full scaleoutput of 80 mA.
The position transducer signal is filtered by the Buffer Amplifier,before being passed through to the PLC analogue input moduleThis ensures transducer and external noisecannot upset the closed loop.
The Buffer Amplifier is housed in a compact DIN rail mountingenclosure and requires a 24 V supply. Front panel test points andvalve drive LEDs facilitate commissioning and trouble shooting.
