Control unit CUMTX2006
We
have developed a microprocessor controller unit for the
management of minor concluded regulated or controlled drive
units on the machinery.
The unit contains the following eqipment:
- 3 inputs to the classical incremental encoders (TTL or
HTL)
- 1 input for the absolute single-turn encoder of position
(SSI protocol)
- 1 * 485 interface for management of the frequency converter
(USS protocol)
- 1 * 485 interface for connection to the control system
(USS protocol or any 485 protocol)
- 4 digital inputs
- 1 digital output
- supply voltage: 24VDC
- RS232 interface (optional)
- Ethernet interface (optional)

Universal controller
Our
company manufactures the universal microprocessor controller.
It is intended to quickly solve particular tasks, where
standard solutions do not exist or are not optimal.
The controller is built modular. The minimum configuration contains:
- a power supply unit and
- a processing unit with the following equipment:
- 5 analogue - digital inputs
- 2 digital outputs (relay)
- RS 232 interface
- EPROM and EEPROM
The controller can be easily extended with the following modules:
- Universal keyboard with a display:
- foil keyboard with 22 keys
- display: 4x20 characters LCD with back light or 6x7 segmental
LED
- 6 additional diodes for clear display of status
- Measuring-interface module:
- interface RS 485 (half duplex, to 500 kbit / s)
- inputs for 2 incremental encoder (TTL, HTL, up to 1 MHz)
- PLC module:
- 24 digital inputs (0 to 30VDC)
- 16 digital outputs (relay)
- 2 analog outputs (8 or 12 bit, +-10V)
With the help of the controller and suitable software it is possible
to rapidly execute custom solutions from simple counters, display controller
unit, inverters, to a two-axes positioning system.

Measuring-communication
interfaces
When performing measurements with online storage results on the ordinary
PC computers, interfaces that transform signals (analogue or digital)
of the sensors into ASCII or binary sequences and transmit them to the
control program in the PC via serial line are necessary. For larger systems,
more monitoring sites in the industrial environments, the separate
places are linked to the RS 485 network and then connected to a PC computer
via the RS232 - RS 485 interface.
That is why we make measuring-communication interfaces for connecting
sensors to the RS232 or RS 485 lines:
- for general use: interfaces for a total of up to 5 analog
inputs and / or digital inputs (analog inputs: +-10V, 0-20mA,
4-20mA, 10 bit resolution, digital inputs 0/24V)
- for the other interfaces by arrangement

Special counters
We
have developed a multi-functional counter, which in itself
combines the functions of several counters, especially
for the needs of the market. The performance of the microprocessors
allows basic functions of counting and measuring as well
as the immediate processing of the results: calculations
of mutual dependence of inputs, statistics management,
communication with the control systems ...
The maximum configuration can process simultaneously:
- up to 5 ordinary impulse counting inputs (2 inputs to
20kHz, 3 inputs to 5 kHz)
- up to 2 incremental encoders (TTL, HCMOS, up to 1 MHz)
Positions and speeds on the individual inputs, comparisons, mathematical
operations, reporting of preset conditions can be processed; the
results can be realized with 4 line LCD display or with 6 digit 7 segmental
LED display. Parameters of the counter are adjusted through the keyboard
with the help of the user program. Remote control is possible via RS
232 interface, network connections through the RS 485 interface.
