Appendix 1: Probe Module (PRB)
The Probe Module (PRB) gathers data from probes and presents 
that information to the Controller Module (CM) for use in inventory 
reconciliation and reports. Each PRB can accomodate 12 probes 
and the system as a whole can accept a total of 36 probes (3 
modules with 12 inputs each) if space allows. Besides working 
with LL2 mag probes, the PRB also works with vapor ow meters 
to perform VRM functions.
Note:  There are 8 inputs in the TS-608’s Probe Module.
Note: All components located in the hazardous area must be Third Party Certied and have appropriate Entity 
Parameters (see Control Drawing 000-1722 in the back of this manual for further information).
