process interface motherboard for 16 pi/ex... modules pi/ex-mb/16/d-sub 1. short description for signal level matching in large or medium-sized process control systems, in particular for applications in which system cabling is used, multiple channel motherboards are available to accept the pluggable pi/ ex-i-interface modules. 16 electronic bases are grouped together on a motherboard on a sturdy, rail mountable pc board base, to accept the pluggable electronic modules. the power supply is fed in centrally. on the system side, a multiple plug allows all modules to be connected directly to the input/output module. C the extremely compact design of these modules allows a high packing density without loss of individual measurement circuit integrity. C typical for pi, the self-coding module electronics need merely be snapped into the electronic base where they lock in to be vibration-proof. C there is no need to remove conductors to replace modules. this simpli?es installation and maintenance reducing time, costs and frequency of faults. C it is simple to retain reserves, as only as many process interface modules as are required at the time of initial operation are installed. costs for otherwise unused channels are therefore not incurred. C just as is the case for the module electronics, each base can be labelled easily and conveniently with the marking material from the phoenix marking range (see modular terminal block catalog). C the development of individual modules to perfectly suit your applications is unrestricted, e.g with different multiple connectors such as elco, d-sub or flk to connect to the phoenix plc system cabling. further features: C redundant supply decoupled from diode C fuse monitoring with led and relay contact (pdt) C terminal points for error messages if the fuse burns C protection against polarity reversal fig. 1 m 3 8 headquarters: ? phoenix contact gmbh & co. ? flachsmarktstra?e 8 ? 32825 blomberg ? germany phone +49-(0) 52 35-3-00 ? fax +49-(0) 52 35-3-4 1200 ? http://www.phoenixcontact.com 127,5 142,5 147,5 150 228 fig. 2
