PR103 MINI-PLC with ETHERNET/RS485 + 26I/O
PR103 is the first akYtec programmable relay with Ethernet on board. It is designed to control ventilation, heating, pump groups and other equipment. Ethernet interface allows to integrate the device into distributed systems, to realize remote control and management of equipment using akYtec Cloud service (Soon). Compact PLC PR103 has 2 RS-485 interfaces on board for data transmission to the upper level.
To expand its own inputs/outputs, the PRM expansion modules can be connected via the internal bus. Algorithm writing is performed by the user in FBD language with support of function blocks on ST in free programming environment ALP.
Algorithm loading and configuration is performed via microUSB, Ethernet or RS-485.
The PR103 is a mini-PLC with advanced communication capabilities thanks to its Ethernet port and two RS485 interfaces, as well as Modbus TCP and Modbus RTU/ASCII protocols. By communicating via RS485 interfaces at the field level, the small PLC PR103 can use the Ethernet port and Modbus TCP protocol to transmit data to the control level of the automation pyramid
The compact PLC PR103 modifications feature 10 digital inputs, up to 10 digital outputs, 6 analog inputs and a modification with 2 analog outputs and no analog outputs. In addition, 4 of the 10 digital inputs can be used as pulse counters that process signals from 100-kilohertz encoders. As for the analog inputs, they are configurable and can handle a wide range of RTD, NTC/PTC, and standard 4-20mA or 0-10V line signals. In addition, the built-in I/O can be directly expanded using two PRM series expansion modules.
Designed to be mounted on a DIN rail in a control cabinet, the PR103 can operate both in an unheated environment at temperatures down to -40°C and in a heated environment at temperatures up to +55°C.
The user program is written in the functional block diagram language with support for function blocks in the ST language in the free akYtec ALP software. The control algorithm is loaded into the device memory via micro USB cable, Ethernet or RS-485.
