Load Cell Modules

Load cell modules are weighing input modules that supply the bridge of the load cell, digitize its millivolt-level output signal and pass it to the PLC as weight information. They are used in dosing, filling and bagging machines and in tank and silo weighing to process weight directly in the PLC program without a separate weighing transmitter. The category includes Delta Electronics DVP201LC-SL and DVP202LC-SL left-expansion modules and AX-501LC10-0A, and on the GMT side the GXM-10L and GXM-20L load cell modules; the product data shows 1 and 2 channels, 4-wire or 6-wire load cell input and 24 bit resolution. Select the channel count according to the number of weighing points, the 4-wire or 6-wire connection according to the cable construction of the load cell, the resolution according to the desired weighing accuracy, and the module type according to your PLC series. A standard analog input module is not a substitute for a load cell module; a load cell requires bridge excitation and its output is at the millivolt level rather than 0-10 V or 4-20 mA.

How to choose Load Cell Modules

Load cell modules are weighing input modules that supply the bridge of the load cell, digitize its millivolt-level output signal and pass it to the PLC as weight information. They are used in dosing, filling and bagging machines and in tank and silo weighing to process weight directly in the PLC program without a separate weighing transmitter.

  • Separate sensing, motion control, logic processing and operator interface requirements.
  • Select signal type, supply voltage, communication protocol and I/O count for the machine network.
  • Verify housing size, sensing distance and PNP/NPN output polarity against the PLC input card.

Frequently asked questions

What is Load Cell Modules and where is it used?

Load cell modules are weighing input modules that supply the bridge of the load cell, digitize its millivolt-level output signal and pass it to the PLC as weight information. They are used in dosing, filling and bagging machines and in tank and silo weighing to process weight directly in the PLC program without a separate weighing transmitter.

What should I compare when choosing Load Cell Modules?

Select the channel count according to the number of weighing points, the 4-wire or 6-wire connection according to the cable construction of the load cell, the resolution according to the desired weighing accuracy, and the module type according to your PLC series.

Where can I find technical details for Load Cell Modules products?

A standard analog input module is not a substitute for a load cell module; a load cell requires bridge excitation and its output is at the millivolt level rather than 0-10 V or 4-20 mA.
