520ADD03 Input/Output Adapter

Converts RS485 or fiber optic connections to WRB in decentralized locations

Requires 520PSD01

Supports up to 16 I/O modules

Applications

I/O adapter 520ADD03 for connecting more than 16 RTU520 I/O modules to RTU520 or RTU540 with RS485 or fiber optic connection

or RTU540 with RS485 or fiber optic connections.

The adapter can also be used to extend the WRB I/O bus in decentralized I/O applications over distances of up to 2 km.

The distance between the I/O adapters needs to be more than 30 centimeters.

In addition, I/O adapter 520ADD03 is used to connect the RTU520 I/O module to the RTU560.

The I/O adapter is always used with the power supply unit 520PSD01.

The module is available in two versions (standard)

– R0001: RS485

– R0002: Glass fiber, 840 nm

Features

The I/O adapter is the first adapter in the DIN rail mounted I/O assembly and it starts with a new virtual rack number.

The adapter converts the SPB I/O bus (Serial Peripheral Bus) with RS485 or fiber optic connection to a WRB I/O bus.

The glass fiber optic module is compatible with the 23OK24 and 560FOC40 modules.

There are two green LEDs on the module to indicate activity on the I/O bus.

The virtual rack address is selectable via DIP switches. In addition, the adapter automatically generates I/O module addresses within the I/O assembly.
