AD-TV 204 EV S-422


The separation amplifier AD-TV 204 EV-S422 serves the galvanic separation of amplification, conversion or adjustment of analogue measuring signals. The slide-in card can contain up to 4 completely independent channels. With all channels input, output and supply voltage are galvanically separated. The channels are also completely insulated amongst each other. At each channel, input signal type and output signal type can be freely selected. A spindle trimmer is located at the front for direct adjustment. Due to the narrow construction (4 TE) up to 84 channels can be integrated in one standard module carrier.
