MOOG Buffer Amplifier G123-815

MOOG Buffer Amplifier G123-815

Description

The Moog Buffer Amplifier interfaces between standard PLC analogue input and output modules, on one side, and a position transducer and a Moog valve, on the other. It simplifies the use of a PLC in closing position loops. The Buffer Amplifier solves the common problem of the ±10V PLC output being incompatible with the valve drive requirements.

Digital noise from the PLC ±10V output is filtered with a switch selectable first order filter and converted to two switch selectable outputs. The first is ± 10V and the second is a switch selectable current output of ± 5mA to ±100 mA. This allows for most Moog electrical feedback (efb) and mechanical feedback (mfb) valves.

Functional features

Compact, DIN-rail mounting: The amplifier is DIN-rail mounted, which not only saves installation space, but also facilitates maintenance and replacement by the user.

Output meets most Moog valves: The G123-815 buffer amplifier meets the drive requirements of most Moog valves, providing broader system compatibility.

Sensor (Probe), Valve and Voltage Zero Test: The amplifier has built-in sensor and valve zero test functions for user-friendly troubleshooting and maintenance.

Vv and lv LED Valve Drive Indicator: With the LED indicator, users can visualise the valve drive status and signal strength, improving system monitorability.

Selection of different filters and different current outputs: Users can select different filters and current output settings to meet different control requirements.

Sensor (Probe) Signal Filter: The built-in sensor signal filter can effectively reduce signal noise and improve the stability and reliability of the system.

Switching selectable voltage or current output: The amplifier supports both voltage and current outputs, which can be switched by the user as required.

Switch selectable valve drive filter: By selecting the valve drive filter, users can further optimise the control performance of the system.
