Irinos Measurement System

The I/O-Boxes provide additional in- and outputs for the Irinos-Box IR-MASTER. They are connected via the IO-Bus.

Types with 8 or 16 digital in- and outputs are available.

An important characteristic of the desktop I/O-Boxes is the integrated 50 watts power supply. It supplies the internal electronics as well as the digital in- and outputs.

 

 

Connectors

oConnectors for IO-Bus.

 

Mains plug

The mains plug is equipped with a protective earth conductor. Hence no separate earth connection is required. However, it is important that the earth pin of the mains cable is connected to earth. The 24V output power will then fulfill the requirements of the protecion class PELV.

 

Protection

All outputs are individually protected against short circuit. Additionally the internal output circuit is protected against thermal overload. The available output power is specified in the data sheet.

 

IO-Bus - Connector

The I/O-Box is equipped with two IO-Bus connectors for further expansion by additional I/O-Boxes. Both connectors are equal. It does not matter, which of the connectors is used.

If only one cable is connected, this will be detected automatically. The IO-Bus will then be terminated internally. This is signalled by the termination LED.

The selection of the IO-Bus address (2, 4, 6 or 8) is made via the rotary switch at the rear side.
