A1A-22 Analog Signal Conditioner

IMAGES

The Anyload A1A-22 is a compact aluminium-cased analog signal conditioner for strain gauge load cells, delivering a selectable 0-10 V or 4-20 mA output from a 24 V DC supply. With IP66 protection and an operating range of -10°C to +50°C (14°F to 122°F), it connects directly to one 350 Ω load cell or up to 8 pcs 700 Ω cells via a junction box.

PRODUCT DETAILS

The A1A-22 is a single-input analog conditioner that converts the millivolt output of a strain gauge load cell into a stable 0-10 V or 4-20 mA signal for PLC, DCS, or data acquisition inputs. Its compact aluminium casting is rated IP66, making it suitable for outdoor or wash-down installations without additional enclosures.

In process control and industrial weighing applications, the A1A-22 is used to interface load cells with analogue PLC inputs in silo level monitoring, hopper weighing, conveyor belt tension measurement, press force monitoring, and on-board vehicle weighing. Its ≤0.02% linearity and 50 ppm/°C voltage or 60 ppm/°C current temperature drift deliver consistent readings across the full operating temperature range.
