The iO-8 is a high-density wired expansion module designed to provide maximum scalability for your security system. Featuring 8 universal I/O terminals, it connects seamlessly to the control panel’s RS485 bus, allowing for a significant increase in monitored zones or controlled outputs. Engineered for performance and stability, the iO-8 is the professional choice for large-scale commercial and residential projects where hardwired reliability is paramount.
Total configuration freedom. Each of the 8 terminals can be independently programmed as a security input (supporting ATZ and EOL) or a programmable output (OC type) for automation.
Connects directly to the control panel via a secure 4-wire RS485 data bus. Ensures near-instant event transmission and continuous supervision by the main panel.
Supports complex circuit types including NC, NO, EOL, and ATZ (zone doubling). This allows you to monitor up to 16 detection points using only 8 physical terminals.
Slim PCB profile designed for easy mounting inside standard security enclosures. Low power consumption makes it highly efficient for battery-backed installations.
8 universal terminals, each software-selectable as Input (IN) or Output (OUT).
Inputs support multiple resistor configurations: NC, NO, EOL, EOL_T, BEOL, ATZ, and ATZ_T.
Outputs are Open Collector (OC) type, capable of switching up to 150 mA – ideal for driving relays or indicators.
Real-time status reporting for every terminal back to the Protegus 2 app.
Fully compatible with FLEXi SP3 and CG17 control panels.
Secure RS485 data bus connection (+DC, -DC, A, B).
Up to 4 iO-8 expanders can be connected to a single system (depending on panel firmware).
Automatic synchronization of all settings via the main control panel configuration.
Integrated tamper input to protect against unauthorized enclosure opening.
Professional-grade protection against electromagnetic interference and voltage surges.
Continuous supervision: the system alerts the CMS and user immediately if the expander loses its bus connection.
On-board LED indicators for instant visual diagnostics of power and data status.
Fast commissioning via TrikdisConfig software – simply enroll by serial number.
Remote firmware updates ensure the expander always supports the latest system features.
Support for individual zone naming and custom output logic.
Minimal wiring requirements: only 4 wires needed for full power and data communication.
