JMDM-2038 Multifunction human-machine interface Pulse width modulation control board with screen
Introduction
JMDM2038 is is a multifunction human-machine interface SMC and a mature controller currently after many years of large-scale industrial applications, it has a strong resistance to interference ability, powerful, stable and reliable. The hardware is made by high performance and industrial grade imported SMC and parts, professional stability, antiinterference circuit design. The software uses C language programme, has good scalability, can realize many functions. It can set the parameter online by the 10 light touch switch on the blue high-definition LCD screen humanmachine interface, and realize control electric valves, pneumatic cylinders, sensors, proximity switch, hall switch, etc...There are a high precision AD sampling chip, up to 18 bits (bits can be adjusted by software according to need) and 4 channels 20 KHZ PWM output, can adjust control by pulse width modulation (PWM), also can control 2 stepping/servo motor at the same time, suitable for all kinds of strong electromagnetic, high-frequency interference etc. Industrial conditions. The stable and reliable, cost-effective and excellent performance function greatly improves the customer's production efficiency and economic benefits

Function introduction
1) 12 channels input: NPN type, input current is 10MA, typical switch input detect voltage is 12V-24V, 5V switch input detect can be customized. 12 channels input can used to detect stroke limited switch, infrared sensor, approach switch, button etc.
The first 6 channels of the 12 channels photoelectric digital quantity input can accept 3 channels AB orthogonal pulse encoder signal input
6 channels transistor output: The max loading current per channel is 4A, output low level effectively, can drive 5-30V work load voltage, can be used to control electric valves, electromechanical relays, solid relays, air cylinders etc.
2) 6 channels transistor output: The max loading current per channel is 4A, output low level effectively, can drive 5-30V work load voltage, can used for some low voltage signals and loading
3.4 channel high speed precious AD analog detect channel: Detected voltage range: 0-5V, also can customized in 0-10V
AD bits be modified by software, can change to 12 bits, 14 bits, 16 bits and 18 bits, the detect speed will be 4ms, 20ms, 60ms and 245ms. IIC bus read the date. Can used to detect and control the analog, such as voltage, current, temperature, humidity, press etc. Analog signal
4. Has a 128*64 LCD screen, the brightness can be adjusted. It can display 4 line 6 columns standard Chinese. Back light can be on-off by software. With RS485 and RS232 communication interface, they can be switched by two jumps
5. There are 10 button on the panel, it can be used to set parameter
