Product Description

The 2R-D7 module allows to control 2 relays using Modbus RTU protocol. Communication with the device can be carried out via RS-485 or UART TTL interface. In addition, the device has 2 control inputs protected by optocouplers (input voltage range: 3.3 V ... 30 V). The voltage from the control inputs is not the voltage directly supplying the relay coil. Note that the selection of the control interface is made by jumpers located on the board. It is not possible to control the outputs using both communication paths simultaneously.


Control:RS-485 / UART TTL
Protocol:Modbus RTU
Baudrate:4800 / 9600 / 19200 b/s (default: 9600 b/s)
Number of inputs:2 pcs.
Number of relay outputs:2 pcs.
Load capacity of contacts:10 A / 250 V AC,
10 A / 30 V DC
Output:2 x NO/NC
Selected features:
  • LED signaling
  • Control inputs protected by optocouplers, which allows the use of control signals with voltages in the range of 3.3 V DC ... 30 V DC
  • UART interface input is goldpin mountable for signals with voltages adapted to TTL level (3.3 V DC / 5 V DC)
  • Ability to configure the device address (with memorization of settings after power loss) in the range of 1 - 255 (default address 255)
  • Ability to set relay trip delay (base unit: 0.1 s, value range: 0.1 s ... 6553.5 s)
  • Protection against reverse polarity of input voltage
Power supply:7 V ... 24 V DC (no power supply included)
Weight:0.046 kg
Dimensions:85 x 49 x 19 mm
