IMPORTANT: Before you start with the installation of the product, read the attached IMPORTANT SECURITY NOTES very carefully and follow all the herein given information very accurate!
Description:
MODBUS/RTU module to collect 2 digital inputs for 10...250Vac/dc signals via serial bus, Host communication: via RS232 or RS485 with MODBUS/RTU slave protocol, Host baud rates: 9600, 19200, 38400 or
57600Bd, no, even or odd parity, 8 data bits, 1 stop bit, Digital inputs and serial RS232/RS85 interface are galvanic isolated, Digital inputs: Voltage: 10..250Vac/dc, Input current per channel: ~1.9mA, Configuration and
testing of module with free PC software MODBUS configurator, Weight: 55g, Dimension (LxWxH): 17,5x90x58mm, Power supply: 12-48V=, Power consumption: <0.5W, Mountable onto a EN50022 DIN rail.
Manual+Software:
To configure our module, you need our free software tool ModbusConfigurator. Read the actual manual for our product very carefully! You will find both things on our homepage

Dip Switch
Description
Baudrate
Use DIP Switch 1 and 2 to select the baud rate:
BR
OFF
OFF:
9600Bd
ON
OFF:
19200Bd
OFF
ON:
38400Bd
ON
ON:
57600Bd
HINT: The correct parity (NONE; EVEN;ODD) is selected
with the software tool, not with DIP switches.
Interface
Selects the physical type of the serial interface:
IF
OFF=RS232
ON=RS485
Function
Selects a special function:
Definition
OFF=The unit ID from the FLASH memory is used
FD
ON=The unit ID is always 255
HINT
After you change a DIP switch, the converter reboots
automatically. Therefore you don't need to switch off and on
the converter to change settings. After a reboot, all three
LEDs are on for a short period to signal the power on
procedure.
