JDM1-9 counter relay is suitable for control circuit with AC50Hz frequency, rated control power supply voltage up to 380V and DC rated control power supply voltage up to 240V as a counting or counting control element.
The JDM1-9 is a count relay designed for control circuits with AC frequency 50 Hz and rated control voltages up to 380 V AC or 240 V DC. It supports a wide range of supply voltages, offers low‑speed (30 counts/s) and high‑speed (200 counts/s) modes, and provides four counting bits with optional add/subtract functions.
The manual includes the main technical parameters, wiring diagrams, timing charts, physical dimensions, installation instructions, and input/output specifications. It also lists environmental limits, power consumption, and contact ratings for proper integration into control systems. This manual is written in Chinese.
