Pros & Cons of Electronic Marshalling for a Safety System
Abstract
Electronic Marshalling represents a new technology for connecting hard wired inputs and outputs to a control system. In lieu of using a twisted pair of shielded wires There are specific and obvious advantages to using electronic marshalling in a safety system, but are there specific disadvantages? This would include the risk incurred in moving from a system that brings specific field inputs to the safety system processor, and instead multiplexes a number of inputs/outputs in a set of fiber optic strands. Electronic marshalling also depends on redundant power being supplied from a local equipment room. The loss of power from the redundant source would mean that a whole junction box worth of safety system inputs/outputs would be lost. This paper will review the advantages and potential disadvantages to the use of electronic marshalling in safety system applications.
