Isolation Amplifier

Isolation Amplifier With Nominal Value Selector AD-TV 32 GL

DescriptionThe VARIO-isolation amplifier AD-TV 32 GL serves the galvanicseparation, conversion and amplification of DC current and voltagesignals (0/4-20 mA and 0/2-10 V DC). The signal dimensions areadjustable at the front. The starting and end values can here be adjustedindependent of each other. Input, output and the supply voltage areseparate from each other with high insulation. An integral electronic widerange power pack with a high degree of effectiveness allows operation ina supply range of 20...253 V DC or 50...253 V AC. Additionally, anominal value can be specified via switch at the front at the output. Theinput measuring signal is decoupled and without influence during this.The nominal value at the output, which can be activated and adjusted viaa potentiometer at the front.

ApplicationConversion, burden amplification and galvanic decoupling of active DC-current and voltage signals with additional manual / automatic operationvia a nominal value specification, which can be activated.

Specific characteristics• Front panel switch for switching between manual and automatic

operation• Value setting for manual operation by front-face potentiometer
