Product Description
    Details

    The programmable relay PR200 is a universal and easy-to-use device designed in a plastic enclosure for DIN rail mounting as an alternative to PLC. 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 I/O-Modules (for example, our modules of Mx110 series).

    The PR200 is programmed in the easy to use akYtec ALP software (available free of charge) using standard FBD programming language (IEC 61131-3). This software offers a library of many function macros and also allows creating your own macros. In addition, there are also available simulation mode and a complete overview of the resource usage. Once the application program is done, it can be transferred to the relay via mini-USB port on the device front panel.

    Other features of the programmable relay PR200 include:
    • Up to 8DI + 8DO + 4AI + 2AO + LCD + 2xRS485 in one device
    • Connecting different sensors 4-20mA, 0-10V, resistance-type (PTC, KTY thermistors, Pt1000) and actuators
    • 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

    PR200 can be used in numerous applications such as building automation, lighting control and access control systems, technical equipment such as pumps, fans, compressors and presses to conveyor and filling systems etc.

    Temperature & Humidity Monitoring

    Monitoring of temperature and humidity is a very common automation task which can be easily solved by means of products from akYtec. A quick and cost-effective solution based on Programmable relay PR200 we have implemented in the sample project below:

    programmable relay

    Pump control

    There are two pumps in this project controlled by the programmable relay PR200. Their operation depends on the signal value from a temperature sensor and two set points. The values of the set points are received from a SCADA system that the PR200 is connected to via Modbus RTU. Both pumps can be stopped by an emergency stop button or through the SCADA system. The temperature values and the status of the pumps are shown on the PR200 display.

    Press machine

    It is shown in this project how the programmable relay PR200 can be used to prevent the operator from accidental injuries when operating a press machine. In addition, there is implemented a counting function and its result is displayed on both the relay's display and the RS485 display SMI2 that is connected to the PR200 via Modbus. Moreover, there is also a testing mode available. For more details, please refer to the project description on the link below:

    Modifiable Week Clock

    Some automation tasks require switching on/off a secondary device according to a particular schedule. Schedules are often subject to change. With this sample project, you can learn how to set, and more importantly, to change the schedule of the output activity with the PR200's function keys and its screen. It means, there is no need to rewrite and re-upload your application.

    Moreover, there are used three macros from our Online Database (“Clock_Mod”, “Day_Week” and “Set value selector”) in this project, so it is a great opportunity to get familiar with them.

Product Questions

    Product Questions

    What software do I need to program the PR200? How much does it cost? Do I need a specialized cable?

    You need our programming software ‘akYtec ALP’. It is free of charge. You can find it either on our website or on the USB stick, which is included in the delivery.

    Yes, you need a cable (USB A-plug to micro B-plug), which is also included in the package.

    Rate the answer?
    How can I change the parameters ‘Start date/time’ and ‘Stop date/time’ of the functional block ‘CLOCK WEEK’ from the front panel of the PR200 or through a variable in akYtec ALP?

    Since the ‘CLOCK WEEK’ does not have any inputs you cannot change the parameters of this functional block both from the front panel and through variables.

    If you need a modifiable ‘CLOCK WEEK’ in your project, two macros are available in the online macro database as well as a sample program that shows how these macros should be programmed.

    To download the sample program, please use this link, open and look for the sample project 'Modifiable Week Clock'.

    You may refer to the following video to see the instructions on how to download the macros:

    Rate the answer?
    How can I change the parameters of a functional block (i.e. BLINK, TON, TOFF, TP) from the front panel of the PR200 or through a variable in akYtec ALP?

    To write to or read from a functional block, it is necessary to use the blocks 'WriteToFB' or 'ReadFromFB', respectively. You can find these blocks on the toolbar ‘Insert’.

    You may refer to the following video to see instructions on how to use these tools:

    Rate the answer?
    Can I expand the number of inputs/outputs of the PR200?

    The main and the simplest way to do it is to use the PRM Extension Modules from akYtec. With these modules, you can extend the PR200 by up to 16 additional digital inputs and up to 16 digital outputs. Alternatively, if your system requires more I/O-points, you can use Modbus RTU/ASCII and connect up to 32 expansion modules over the RS485 interface. We recommend using our I/O-Modules of the Mx110 series for this purpose.

    Rate the answer?
    How can I connect an expansion module of the Mx110 series to the PR200?
    A module of Mx110 series can be connected to the PR200 via the RS485 interface and Modbus protocol.
    Rate the answer?
    What is the maximum permissible frequency that a digital input of the PR200 can handle in case of using this input to read an impulse signal?

    This frequency depends on the device variant.

    PR200-230.X.X:10 Hz

    PR200-24.X.X: 250 Hz.

    In either case, a square wave pulse signal with 50% duty cycle is assumed.

    Rate the answer?
    Are the relay outputs of the PR200 suitable to control a power contactor?

    It depends on the switching current of the power contactor. A relay output of the PR200 has the following switching capacities:

    AC: 5 A, 250 V (resistive load)

    DC: 3 A, 30 V. 

    Rate the answer?
    Can the integrated voltage source of a PR200-230.X.X be used for feeding an input module Mx110-24.X? What about feeding an ITP16 or ITP14?
    No, this voltage source cannot be used for feeding an Mx110 module because it doesn’t provide enough current (max. 100 mA). However, this current is enough for both an ITP display or its analog output.
    Rate the answer?
    What is the minimum voltage and current needed for proper operation of an input of the PR200?

    It depends on the device variant:

    PR200-230.X.X: 159 V and 0.75 mA.

    PR200-24.X.X: 15 V and 5 mA.
