OPERATION AND APPLICATION
2.8.2 The External Input/Output Points
The UNILINK Adapter provides a single external input point and a single
external output point. These two points operate independently and can be used
in a variety of applications like a remote "Adapter Good" indicator. For safety
critical applications, any external alarms should be hard-wired independently
of the P/C.
