+10...+24V DC
RS485-Bus
Connections
0V
Power supply and bus line are pluggable. All other connections are screw terminals.
Power supply: ....................2-pole COMBICO plug connection
Bus connection: ................2-pole COMBICO plug connection
I ⁄ O connections: ...............Screw terminals designed for strands up to 2,5 mm
Power supply LED
The power supply LED is located at the front side of the device at the bottom left.
The green LED [Rx] signalises the presence of power supply.
Communication LED
The communication LEDs are located at the front side of the device at the top left.
The green LED [Rx] signalises data traffic on the bus line (arriving data).
The red LED [Tx] signalises that field bus device is sending data to the bus line.
Rx Tx
Configuration
The position of DIP switches is at the top, centred.
The bus termination is located between bus connector and DIP switches.
RS485 BUS TERMINATION
The terminating resistor for bus termination is already built-in in the device and
can be activated via jumper as needed.
