A2A-D2 Load Cell Amplifier

The ANYLOAD A2A-D2 is an aluminum-cast analogue amplifier designed for conditioning the signal from strain gage load cells in weighing systems. It accepts an input range of 0 to ±36 mV and delivers a 0-10 V / 0±10 V or adjustable 4-20 mA output, with linearity of 0.02% or better. A single unit can drive up to eight 350Ω load cells, making it a practical choice for engineers and OEM designers building tank, hopper, platform, and process weighing systems. The IP66 aluminum enclosure protects the electronics in demanding environments.

Installation is straightforward. The compact housing includes captive stainless steel cover screws and a preinstalled GORE breather vent, and it can be wired directly to one or two load cells or to several cells through a junction box. The datasheet provides a dimensional drawing with a full table in millimeters and inches, an M4 mounting thread specification, and a connection diagram showing the terminals for both load cell inputs, the voltage and current outputs, excitation selection (5 V or 12 V), gain, and zero/span adjustment. Documented specifications include the 24 VDC ±20% power supply, maximum power, input offset voltage, common-mode rejection ratio, voltage and current full-scale temperature drift, and an operating range of -10 to 50°C (14 to 122°F), so you can specify and install the amplifier without guesswork.

The A2A-D2 is offered as part number A2A-D2 with an approximate shipping weight of 0.5 kg.
