Encoder Controller

The Instruction Of JMDM-2011 Encoder Controller

Description
JMDM-2011 encoder controller is one type of JMDM-2011 Multifunctional HMI industrial controller which is designed by Shenzhen Jing Min Digital Machine Co., Ltd...It can accurately position and measure the distance by connecting an encoder, meanwhile, and can control 12 digital input signals and 8 digital output signals.
1.1 Basic parameters of JMDM-2011 encoder controller
12 channels optical isolation digital input, the type is NPN, max input current is 10MA; 2 of 12 inputs can be used as interrupt source of high-speed accounting.
8 channels optical isolation digital output, the output type is open collector, max output current is 1A, max output frequency is 20KHZ.
The product can connect an encoder or an electronic ruler to realize the position detecting.
1.2 Application
This product can be used in various controlling systems within 20 channels. It can control cylinder, solenoid valve, relay and encoder. It can also connect various sensors, for example, photo electricity mode, capacitance mode, inductance mode, Honeywell mode and etc.
It can replace various PLCs within 20 channels to be applied to all kinds of controlling situations (e. G. Various machines control). By flexible and powerful programming, JMDM-2011 encoder controller is more powerful and precise in function, more compact in shape than all kind of PLCs.
1.3 Working principle
The encoder transforms Angle signals into A phase and B phase Pulse singnals, the max frequency of the encoder that JMDM-2011 encoder controller supports is 200KHZ. JMDM-2011 encoder controller transforms pulse singnals into digital number, but precision of the measurement is determined by the encoder. If the parameter of the encoder is that a round ( 360° ) corresponds to 1000 Pulses, when the encoder revolves some angle, then JMDM-2011 encoder controller can receive and process these pulses signals, and accurately display the number of pulses on the LCD screen by programming, therefore the accurate positioning is realized by JMDM-2011 encoder controller and an encoder.
