YL-48S intelligent time relay is a multi-function time relay with rich control functions, high control accuracy, strong hardware anti-harmonic interference ability, and easy operation. The main features of the product are as follows: rich time setting (seconds, minutes, hours), two main control relay output modes can be selected according to the needs of industrial control (1 group instantaneous 1 group delay or two groups of double delay), time control mode can be selected (power-on delay control, on-off cycle delay control, manual jump reverse delay control), time to position reset mode can be selected (manual zero reset or automatic zero reset), time delay accuracy decimal point position can be selected (0.01S (M, H), 0.1S (M, H), 1S (M, H) three control accuracy), timing direction can be selected (add timing or subtract timing).
This manual describes the YL-48S multi‑function time relay developed by the manufacturer. It covers the device’s features, control accuracy, harmonic‑resistance, and easy operation, including various time‑segment settings and output modes.
The document includes panel indicators, key functions, menu navigation, technical parameters such as power supply options and contact ratings, as well as installation dimensions and wiring diagrams. This manual is written in Chinese.
