S81-MOD-BIL Weighing Module
The S81-MOD-BIL module, together with the S81-F7008-1 module, allows to monitor cylinder
load status and to signal even the slightest extinguishing gas leakage without delay. The weighing
module communicates with the control module through the RS485 bus that accepts up to 32 mod-
ules. Two thresholds, pre-alarm and alarm, can be set per weighing module when programming.
