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 flow 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 Certified and have appropriate Entity
Parameters (see Control Drawing 000-1722 in the back of this manual for further information).
