AD-AS 320 GS

Description

The analogue memory AD-AS 320 GS serves the galvanic separation, conversion and amplification of DC current signals and voltage signals (0/4-20mA or 0/2-10V). The device can save an analogue value over an unlimited period. With an active control signal (24V active or contact), the output signal follows the input signal. If the control signal is deactivated, the instantaneous output signal remains saved. The saved value is also restored after a supply voltage failure. Alternatively, the analogue value can also be taken over to the output by pressing the memory key briefly. An activation of zero trimmer and full trimmer is possible by pressing the memory key for longer (only in signal sequence mode). With this, the signal dimensions can be adjusted at the front in the range of ±25%.
