STG/IN8-S remote input module
STG/IN8-S remote modules are field mounted and are connected to the panel via
RS485 buses. They are used to connect 8 x 4-20mA analog gas detectors. Each
module must be addressed using the rotary switches on the PCB. The address must be
univocal and between 1 and 255. For the maximum number of modules, see the table at
chapter. 1- Introduction
