Webguide Amplifier EH321B / EH322B

Webguide Amplifier EH321B / EH322B


The Web Guide Amplifier amplifies signals from the sensors to operate the Servoguide controller, and also functions as a controller.

Changeover between automatic and manual operation can he done with the manual operation pushbutton switch. Truce models are available depending in the type of sensor.



Control output -200 to 0 to +200mA DC (load 20 Ω , moving coil)(max. ± 250mA DC)
Dither : 4Vp-p, 50/100Hz rectangular wave
Power supply voltage 100 to 240V AC, automatic changeover, 50/60 Hz
Power consumption 100VA
Solenoid valve * Power supply voltage
