The KL-620 Sensor and Transducer Interfacing Trainer is a comprehensive control training system that incorporates industrial-grade components with various control circuits. Its modular and closed-loop control circuits allow implementation of open-ended, individual control loops as used in industrial applications.

The KL-620 uses only industrial standard sensors and transducers (0 ~ 10V, 4 ~ 20mA), and is equipped with an RS-232 interface for computer control experiments. Control programs can be written on a personal computer and down-loaded to the on-board 8031 microcontroller.

KL-620 Main Unit

The main unit incorporates all necessary equipment for use with the eight standard and eight optional plug-on training modules. A socketed industry-standard 8031 microcontroller is fitted to the system, along with a monitor EPROM, and may be programmed from an IBM compatible personal computer by way of an RS-232 link.

The main unit also contains a 12-bit analogue to digital converter and 12-bit digital to analogue converter, as well as amplifiers and a multi-rail power supply.
