MULTISCAN++ microprocessed control unit for 32 detectors with 2 RS485 loops. 2 loops with open RS485 protocol (EIA-485). Galvanically isolated loops. Ports: 2 x RS485, 1 x RS 232 (for configuration from PC.). Graphic display. Up to 256 inputs through STG / IN8S modules. Up to 32 open collector (O / C) outputs via STG / OUT16S modules. Relay outputs through additional STG / 8REL modules. 8 preconfigured relays in the control unit. 8 4-20 mA inputs are included for detection on the panel itself. Remote modules require external power supplies with project capacity. Includes ST.G / MTSS1-CONF programming upload and download software. Requires two 12 Vdc 7 Ah batteries (not included). Expandable to 4 loops using STG / SER cards.
