Compact 4-20mA/0-10V/mV Signal Calibrator for PLC DCS ESD

The LB78 signal generator is designed to cover most of the functions required for the maintenance of PLC, DCS, ESD, field instruments, regulating valves, and frequency changers. It offers long-term stability and high precision.

The output signal options include V: 0-11.00V, mA: 0-24.00mA, and mV: 0-110.0mV. The device can operate in a wide range of environmental conditions, with a temperature range of -10 to 50°C and a humidity range of 20% RH to 80% RH.

The compact dimensions of the LB78 measure 108 * 66 * 20mm, making it easy to carry. The power consumption varies depending on the output signal, with V and mV outputs lasting up to 20+ hours, and mA output depending on the current draw.

The package includes the LB78 Signal Generator, a USB charging cable, a carry bag, and an English manual. The device is characterized by safety protection, with a comprehensive set of features and a clear display. The brand shell has a grit finish, which provides resistance to soiling and scratches.

One of the key features of the LB78 is the built-in one-time quick-break fuse, which can prevent instrument damage caused by misinserting the electric supply with 110V or 220V. Additionally, some of the critical components, such as the DA, reference voltage, and operational amplifier, use stable chips with high temperature and high reliability, which helps to improve the temperature stability and long-term aging performance of the instrument.

The rational key layout ensures that all functions have independent corresponding keys, making the LB78 easy to operate. The device also has low power dissipation and a long standby time, further enhancing its usability.

In summary, the LB78 signal generator is a high-quality calibrator that offers a comprehensive set of features, long-term stability, and high precision, making it a reliable tool for the maintenance of various industrial equipment.
