Description：

The Load Cell Central OM-19-2 is a DIN rail mountable load cell amplifier designed to provide precise load and force measurement for industrial and motion control applications. Acting as a signal transducer, it converts load cell signals into standard analog outputs for integration with industrial control systems.

The OM-19-2 operates from a 24 VDC power supply input and provides a bridge supply output of 3–10 V, supporting compatible load cell configurations. It offers multiple analog output options to accommodate different control system requirements.

For signal transmission, the amplifier provides a 4–20 mA current output, as well as 0–10 V DC and ±10 V DC voltage outputs. These standard analog outputs enable connection with PLCs, controllers, and other industrial equipment that accept current or voltage input signals.

Frequently asked questions

Q : What is the OM-19-2?

A: It is an industrial-grade DIN rail mountable load cell amplifier (transmitter) designed to amplify weak millivolt (mV) signals from load cells into standard industrial analog outputs like 4-20mA or 0-10V.

Q : What is the required power supply input?

A: It operates on a standard nominal 24V DC power supply.

Q : How many load cells can I connect to a single OM-19-2?

A: It features a high-current excitation output capable of driving up to four 350-ohm load cells or up to eight 1000-ohm load cells simultaneously.

Q : What is the maximum loop impedance for the 4-20mA current output?

A: Powered at 24V DC, the current loop output can drive a maximum loop load resistance of 1000 ohms.
