Servo Amplifier AHT-SA
Analog electronic module for controlling a single servo valve. Input signal is ±10V. Output signal is Imax=±115mA.
A 0...+10V input signal gives a current of 0 to +115mA to the servo valve, a 0...-10V input signal gives a current of 0 to -115mA to the servo valve. Many amplifier characteristics can be adjusted with front panel trim resistors or selected with internal switches.
Analog Amplifier AHT-AU
Analog electronic module for controlling a single solenoid. Input signal is 0...10V. Output signal to coil is Imax=3A.
The 0...10V input signal of the amplifier is converted proportionally to an analog output signal. With an input signal of 0...10V the coil will have a proportional continuous signal with a current of 0 to 3A.
PWM amplifier AHT-PWM/1
Digital electronic module for controlling one proportional valve with two coils. Input signal is ±10V. Output signal to coils is Imax=3A.
The input signal of the ±10V amplifier is converted proportionally into pulse width modulated (PWM) output signals. With an input signal of 0...+10V the A coil will have a proportional current of 0 to 3A, with an input signal of 0... -10V the current will be on coil B.
PWM amplifier AHT-PWM/2
Digital electronic module for controlling two independent coils. Input signals are 0...10V. Output signal per coil is Imax=3A.
The 0...10V input signal of the amplifier is converted proportionally to a pulse-width modulated (PWM) output signals. With an input signal A of 0...+10V the A coil will have a proportional current of 0 to 3A, with an input signal B of 0... +10V the current will be on coil B.
Charge Amplifier AHT-CH
A matching device designed to connect piezoelectric transducers to measurement modules.
It is a single-channel charge transducer and is designed to operate with piezoelectric measuring transducers (e.g. accelerometers), output value of those is an electric charge (measurement of vibrations, pressure pulsations, etc.). 
USB-RS485 Converter
USB-RS485 converter is intended for converting the USB to serial RS485 interface. The converter features the galvanic separation. 
The device allows to connect devices through USB port to RS485 industrial network, e.g. personal computer, industrial controller, etc.
Sinus to square wave pulse Converter
Sinus to square wave pulse Converter is intended for frequency input signal transducing to standardized pulse signal with amplitude of 24V, furthermore the pulse frequency is equal to the input signal frequency.
An analog AC signal, with frequency proportional to the turbine speed, from the turbine converter is fed to the Sinus to square wave pulse Converter input, where it is converted into a 24V pulse signal of the same frequency, which can be fed to any counter, calculator or a digital module for determining the fluid flow rate.
