Trikdis iO-8 expansion module | 8 inputs/outputs | RS485 bus | G16, GT+, SP3, CG17

The Trikdis iO-8 is a wired expansion module that adds 8 universal terminals to the security system. Each terminal can be set in software either as a security input (NC, NO, EOL, EOL_T, BEOL, ATZ, ATZ_T) or as a programmable open-collector (OC) output, for example to drive a relay or an indicator. In ATZ mode (zone doubling) up to 16 detectors can be monitored with the 8 terminals. The module connects via a 4-wire RS485 bus (+DC, -DC, A, B), and the panel supervises the connection continuously – a lost connection is reported immediately to the monitoring station and the user. The module's settings are synchronised with the panel configuration; it is enrolled in TrikdisConfig by its serial number. According to Trikdis the iO-8 works with the FLEXi SP3 and CG17 control panels and also expands the terminals of the G16 (3G/4G) and GT+ communicators. Up to 4 iO-8 modules can be connected to one system (depending on the panel firmware).
