1 Overview
The programmable relay PR200 is a small controller. User application is created as a
function plan with the programming software ‘akYtec ALP’, included on the USB stick. The
user application includes the logic programm as well as the device configuration. The PR200
enables the following functions:
− control of the outputs according to the input status and the logic of the user
application
− configuration with the function buttons or using ALP software
− comprehensive programming of LCD display
− 2 programmable LEDs
− Master and / or Slave in a Modbus network
− Real-time clock
− extension modules
The device is designed in a plastic enclosure for DIN rail mounting.
The enclosure has 3-level stepped form for distributor installation. Indicators and control
elements are located on the front housing. There are mounting interlocks on the rear side.
Plug-in terminal blocks are placed on the upper and lower stepped surfaces. The blocks are
used for connecting actuators, digital and analog sensors, RS485 network lines and other
external equipment.
Plug-in terminal blocks enable quick and easy replacement of the device.
Front housing:
− 2-line alphanumeric display (16 characters each)
− two LEDs: F1 (green) and F2 (red), controlled by an application
− 6 function buttons for system menu and display
navigation
Under the front cover (rights):
− Connector EXT (10 pole) for extension modules
− Mini-USB socket PRG for connecting to PC. USB A-plug to micro B-plug connection
cable is included in the package.
The relay is available in several versions, for DC and AC voltage, equipped with only digital
or a combination of digital and analog inputs and outputs. The device has a 2-line 32-
character LCD display. A real-time clock and up to 2 RS485 interfaces for connection to
Modbus networks are available. The relay can be expanded with additional input and output
modules. The analog inputs can be configured as analog or as digital.
