INTRODUCTION
DigiRail-2R
Modbus Module for Digital Outputs is an electronic unit with two digital relay outputs. An RS485 serial interface allows you to configure
and activate the outputs through the communication network. It is suitable for mounting on DIN rails 35 mm.
The outputs are electrically isolated from the serial interface and the module power supply. There is no electrical isolation between serial interface
and power supply.
The
DigiRail-2R
configuration is performed over the RS485 interface, through Modbus RTU commands. The
DigiConfig
software allows you to
configure and perform diagnostics of all
DigiRail-2R
features.
DigiConfig
offers features to detect the devices present in the Modbus network and
configure the
DigiRail-2R
communication parameters.
This manual provides instructions for installing and connecting the module. The
DigiConfig
installer and documentation for the
DigiRail-2R
Modbus
communication (
DigiRail-2R Communication Manual
) are available at

SPECIFICATIONS
Outputs:
Two independent outputs with relay SPDT, 8 A @ 250 Vac or 8 A @ 30 Vcc (resistive load).
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 supply
: 10 to 35 Vdc. Typical consumption: 90 mA @ 24 V. Internal protections against polarity inversion.
Electrical insulation between outputs and power supply/serial port:
2000 Vac
Serial communication:
2-wires RS485, 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, located on the front panel, puts the device into diagnostic 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
: Signals that the device is sending data on the RS485 line.
•
RX
: Signals that the device is receiving data on the RS485 line.
•
Status
: When permanently lit, signals that the device is in normal operation; when blinking every second (approximately), signals that the
device is in diagnostic mode.
Configurator software in Windows environment:
DigiConfig
