The Massload ML 4-20MA is a cost-effective 2-wire 4-20mA signal conditioner, powered from a wide 9 to 30 VDC supply. Compatible with most standard load cells, it is designed for straightforward integration into PLC-based process control and data acquisition systems.
The Massload ML 4-20MA is a reliable, budget-friendly load cell signal amplifier built for everyday PLC and process control applications. It converts the millivolt output of a standard strain gauge load cell into an industry-standard 4-20 mA two-wire current loop signal, eliminating the need for a separate power supply input line.
Its wide power supply range of 9 to 30 V DC ensures compatibility with virtually any control cabinet supply, while its compact form factor allows it to be mounted directly inside a load cell housing or a PVC enclosure for inline applications. The ML-4-20MA is well-suited for load cells or scales with 2 mV/V rated output & 350 Ohms input bridge resistance. With minimal wiring and no complex configuration, it gets systems running quickly and dependably.
