The Siemens SITRANS LU SAM Satellite Alarm Module provides up to 20 relay outputs for the measurement points of the SITRANS LU10 level monitor. All relays are Form C to allow NO or NC wiring.
The operation of the Siemens LU SAM is programmed via the LU10. The only on-board settings are for output testing and bank selection. Using a SITRANS LU SAM, you can have two relay outputs for all ten measurement points, all 20 for a single measurement point or any combination between the two.
