JMDM-COM4DI2DOMR Is an industrial-grade high-performance mini-PLC which independent research and development by Shenzhen Jingmin digital machine Co., Ltd. It is can programmable logic controller. It is all be called 4 input and 2 output serial port controller, 6 points digital (IO) SCM serial port controller, it is the minimum system of the JMDM serial SCM serial port controller at present. 4-channel full Opto-isolated digital input, 2-channel Opto-isolated and relay isolated output, anti-static, anti-strong electromagnetic interference, each channel of the maximum load is AC220V*10A,DC24V*10A, RS485/RS232 interface can to be selected.
Technical parameters of the equipment:
1. Working power: DC24V (or AC18V 1A), can customize for DC12V 1A (or AC12V 1A); Controller comes with the rectifier circuit, input regardless of negative and positive, so AC and DC can universal.
2. 8 high-performance SCM control;
3. 2 kinds of communication interface is optional: 1 RS485 interface and 1RS232 interface can select by setting the two short-circuit cup. A standard RS232 serial port communication interfaces (anti-15KV static shock), can communicate with computer and other host computer, etc. Constitute a large communication system; can directly download procedure by RS232 interface, non-burner, convenient for program modify and upgrade.
4. The working status indication of the controller: two LED lamp display the power supply and running status respectively;
5. Two-channel relay output: Opto-isolated and relay isolation of two isolated outputs, stronger anti-interference ability, no dry contacts form, can directly control the maximum AC of 220V voltage and DC 24V; each channel of maximum output current is 10A; the output interface can read back.
6. 4 opto-isolated digital inputs, inputs voltage range of the digital input is 3.3V-24V; input current for 5-10MA; can be used for the detection of external signals of sensor input, such as photoelectric sensors, infrared sensors, Hall sensors, proximity switches, inching switches, and other digital input devices, etc.
7. System stability: relay output using high-frequency filter circuit to produce minimum harmonic; to make the system have a high stability and long working life;
8. Three kinds of working way: supporting of independent control( can be used for C language programming), RS232 serial monitoring ( the maximum communication distance is 10 meters), RS485 serial monitoring( the maximum communication distance is 1KM)
9. System stability: with industrial lightning-proof, Anti-strong electromagnetic interference, high reliability performance, no crash.
10. Digital working status indicator light: each digital input and output has a indicator light, easy to observe the I / O working state;
11. Dimensions: Housing: 115mm × 90mm × 40mm; PCB board: 91mm × 85mm × 22mm.
