STG/IN8-PK REMOTE INPUT MODULE
STG/IN8-PK 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 ad-
dress must be univocal and between 1 and 255 (1-247 for the Modbus protocal).
For the maximum number of modules, see table 1.

STG/OUT16-S REMOTE OUTPUT MODULE
STG/OUT16-S remote modules are field mounted and connected to the panel
via RS485 buses. They provide 16 Open Collector outputs (negative switch) with
programmable functions to remotely trigger Sirens, Solenoid valves, Relays, etc.
Each STG/OUT16-S module can be connected to up to 2 boards of 8 relays that
convert the Open Collector output to a powerless exchange contact.
Each module must be addressed using the rotary switches placed on the PCB.
The address must be univocal and between 1 and 255 (1-247 for the Modbus pro-
tocol). For the maximum number of modules, see table 1.
