Programmable relays

Programmable relays of akYtec are programmable small PLCs that do not include a previously written program in their internal memory. Devices of this type can also be called intelligent relays, small logic controllers, compact PLCs, mini-PLCs, etc. The control algorithms of these devices are created directly by the user, making these simple PLCs versatile in residential and communal sectors, in agriculture as well as in various sectors of industry. Due to the internal logic of our smart relays, the use of electromagnetic switching technology can be significantly reduced, which decreases the wiring and installation cost and increases the reliability of your systems. Future system adaptations can be elegantly solved by the user due to the freely available and easy-to-use akYtec ALP software, without having to intervene in the circuit.

Our programmable control relays allow solving both simple and complex control tasks. Choose the device that suits your project based on the varying numbers of inputs and outputs as well as the required power supply.

All versions of our compact logic relays can be integrated into any RS485 Fieldbus network. For the PR1XX logic modules, the interface adapter PR-MI485 is required to address the devices as Modbus slaves. The PR200 can be operated as a Modbus master. All devices can be operated in the temperature range from -20 to +55 °C. The devices of the PR1XX series can be attached either to a wall or a DIN rail. The PR200 is supplied only for DIN rail mounting.

Under most circumstances, many PLC-controlled systems include real-time algorithms therefore all versions of our programmable relays are equipped with a real-time clock.

Using our compact programmable relays, it is possible to develop simple process control systems based on the relay logic, for example:

  • - Roller shutter, heating, ventilation, pump or awning control
  • - Access control
  • - Door/gate control
  • - Lighting systems, light grids
  • - Fireplace control
  • - Conveyors control
  • - Painting lines

  • SMI200 Programmable compact controller
    Compact and easy-to-mount panel PLC The SMI200 is a compact symbolic operator panel with control logic. It is designed for displaying and editing textual and digital parameters of a system and can be used in harsh operating conditions alongside programmable relays, controllers, or input/output modules connected via an RS-485 network. The SMI200 comes equipped with an RS-485 interface for device control over the network or data transmission to the upper level. The device programming is carried out using akYtec ALP programming software over micro-USB. The SMI200 enables control and regulation of indoor or outdoor lighting, heating, ventilation, and pumps as well as roller shutters and doors.

  • PRM Extension module
    PRM provides the quickest and the most convenient, as regards installation and configuration, digital or analog I/O extension for the PR200 Programmable Relay from akYtec. This module connects to the PR200 base unit directly over the internal bus, which ensures much faster and reliable communication as if it would be the case with RS485/Modbus. Moreover, the communication over the internal bus requires no additional I/O configuration as it is with Modbus registers.
