INSTRUCTION MANUAL
INTRODUCTION
The Modbus Module for Digital Outputs - DigiRail-2R is an electronic unit with two digital relay outputs. A serial interface
RS485 allows the configuration and activating of these outputs through the communication network. It's appropriate for
mounting on DIN 35 mm rails.
The outputs are electrically insulated from the serial interface and the module supply. There is no electrical insulation
between serial interface and supply.
Configuration of the DigiRail-2R is performed through the RS485 interface by using Modbus RTU commands. The
DigiConfig software allows the configuration of all features of the DigiRail as well as its diagnostics. The DigiConfig
offers features for detecting the devices present in the Modbus network and for configuring the communication
parameters of the DigiRail-2R.
This manual provides the instructions for installation and connection of the module. The installer for DigiConfig and the
documentation regarding Modbus communication for the DigiRail-2R (Communication Manual of the DigiRail-2R) are
included in the CD-ROM which accompanies the product. They are also available for download at

SPECIFICATIONS
Outputs: Two independent outputs, with relay SPDT, 8 A, 250 Vac
Timing for activating the output relays: 32 bits (up to 4.294.967.295 hundredths of seconds), optional and
configurable for each relay
Dielectric strength between open contacts: 1000 Vac
Power: 10 to 35 Vdc / 90 mA maximum. Internal protection against polarity inversion.
Electrical insulation between outputs and supply/serial port: 2000 Vac
Serial communication: RS485 at two wires, Modbus RTU protocol. Configurable parameters: Communication speed: from
1200 to 115200 bps; Parity: even, odd or none
Response time to the commands: 6 ms
Bounce time (NA/NC): 3 / 6 ms
Key for restoring communication parameters: The RCom key, at the front panel, will set the device in diagnostics
mode (baud rate 1200, parity even, 1 stop bit), able to be detected and configured by the DigiConfig software.
Frontal light indicators for communication and status:
TX: Signalizes that the device is sending data on the RS485 line;
RX: Signalizes that the device is receiving data on the RS485 line;
Status: When the light is permanently on, this means that the device is in normal operation; when the light is
flashing in a second interval (approximately), this means that the device is in diagnostics mode.
