Introduction
1.1 General Description
The 960CI-200 series Communications Isolator is designed for use in Victoreen’s 960 Digital Radiation Monitoring
System for Class 1E applications. Its function is to isolate the safety related monitor from a commercially rated
computer both electrically and mechanically. The monitor transmits data serially to the 960CI isolator through a fiber
optic cable. Figure 1-1 is a block diagram of the Communications Isolator Module.
1.2 Application
The 960CI-200 series Communications Isolator Module is used for communication isolation whenever a safety related
monitor needs to be connected to a computer. This isolation is for the serial asynchronous communication link. The
960CI is designed for use with the 960IC Card Cage Assembly, which holds up to 8 960CI modules.
1.3 Specifications
General specifications for the 960CI-200 Communications Isolator Module are listed below. The module (960CI-200)
is only available rated for nuclear safety-related applications. However, the module may also be used in commercial
applications.
The 960CI-200 module is assembled by techniques and with parts selected for the reliability required in a nuclear
application. Any repairs made to the nuclear rated module will void its safety-related rating. The module (960CI-200)
must be returned to the factory for authorized qualified ANSI 45.2.6, 1978, Skill
Level II service.
