Brief introduction

Built in electrical isolation and anti-static design, reducing serial interface damage, sensor interface failure, weight instability, and intermittent communication with sensors caused by on-site grounding issues; The surge protection design of the sensor interface of the instrument improves its ability to protect against lightning surges. It can be connected to the Keli E-type digital sensor and is suitable for static digital truck weighing systems. (The suffix AC is for transformer specifications)
