Industrial Controller Io Stepping Motor Controller

Introduction
JMDM-EX20DIOMR/MT is shenzhen jingmin digital machine co., LTD., independent research and development of a high-performance small industrial programmable logic digital quantity extension (I/O )control extend board, with JMDM-20DIOADD two axis motion control system board or JMDM-16ADDA analog quantity control mainboard combination use to extend IO.

Performance parameter
JMDM-EX20DIOMR/MT digital quantity expansion board technical parameters and characteristics are as follows:
1.Input point: 12 channles photoelectric digital quantity input, the input signal is NPN, low level is effect; Can also be customized for the PNP. there are 2 channels digital quantity input can be used as the interrupt source, can be used for high speed counting; Can connect the photoelectric, capacitive, inductive,hall various sensors type and input switch;
2.Output point: 8 channels relay or 8 channels transistor output.
8 channels relay output for relay normally open output form, the maximum working current is 5A, maximum working voltage is 220V. AC-DC;
8 channels transistor output transistor is normally open output form, the maximum working current is 5A, maximum working voltage is DC 24V;
3.Programming: extended board is controlled by the main programming, the mainboard use of programming software for the Keil C (singlechip C language);
4.Work power: extension board directly obtained from the motherboard expansion slot work 5V power supply;

Product feature
System reliability: 1.This controller adopts high-performance imported industrial chip design, can adapt to high electromagnetic interference industrial environment (250A discharge welding occasion work); Using external watchdog circuit and input/output full photoelectric isolation and high frequency filtering characteristics of strict, make the system stable and reliable work;
2.Using hardware high-speed operation;
3.Between mainboard and extension plate connection: electric connection use 40 chips extension cord connect,mainboard and expansion board is physical connection for copper double-screw bolt; Maximum can connect 5 board constitute a large control system;

Usage
Using integrated superposition compact design, no shell, easy installation, use convenient hole fixed installation.
The main board PCB size: length x width x high: 190 mm * 85 mm * 28 mm;
Expansion board: length x width x high : 90 mm * 85 mm * 28 mm, mounting holes size: length x width: 82 mm * 77 mm; Can be used directly on the motherboard, use double-screw bolt installation;

Application
1.With motion control board (JMDM-20DIOADD) use, expand more I/O input/output points,encoder input points, can control cylinder, solenoid valve, relay, and external photoelectric, capacitive, inductive,hall various sensors type;
2.Can with analog board (JMDM-16ADDA)use, constitute analog quantity and digital quantity control system;
3.Can flexible application within 120 points of I/O control analog quantity control, motion positioning control, all kinds of industrial automatic control occasions, such as metallurgy, chemical, plastics, printing, textile, food, packaging and other industries in the production machinery, industrial assembly line, industrial control equipment of various kinds of machine tools.
