Brief Introduction

3500/04-01

The 3500 Internal Barrier is an intrinsically safe interface that provides explosion protection for sensor systems directly connected to the 3500 Machinery Protection System.The internal barrier is fully compatible with the 3500 system, providing a convenient and cost-effective solution for installing all types of transducer systems in hazardous areas.The internal barriers of the 3500 rack are integrated in special monitor I/O modules.These barriers provide explosion protection for sensor systems connected to the 3500 system. The intrinsically safe (IS) grounding module provides an IS grounding connection through the 3500 system backplane.The IS Earth Module requires a dedicated I/O module location and it is forbidden to use this monitor location for other 3500 system modules. This limits the standard 19-inch rack to 13 monitor positions.
