Introduction

Remote I/O systems, consisting of I/O modules, gateways, bus termination
modules, power supplies, and a backplane, form the interface for signals to be
transmitted from the explosion hazardous area (Ex area), to the safe area (non-
hazardous area). With appropriate surrounding enclosures, remote I/O systems
can be installed in Gas-Ex areas of Zone 1. Using remote I/O, a wide range of
digital and analog sensors and actuators can be connected to process control
systems over a fieldbus. Specific measures need to be taken to disconnect I/O
modules with Ex-e front connectors during ongoing operation. To do so,
observe the safety notices in this manual. The gateway is the interface between
the I/O modules on the backplane and the process control system. Power
supplies are used to power the I/O modules and adapter/gateway.

All components of the FB remote I/O with Ex-q protection meet the FB
concept. This simplifies the evaluation of modules from an explosion
protection point of view.

This manual sets out how to work with the hardware. Refer to the software
manual for the gateway and the I/O modules for information on the
configuration of the gateway and the I/O modules.
