The I2005S8 is an expander module with 8 digital outputs via relay contacts for the I2004 interface. Up to 4 I2005S8 can be linked for each I2004, thus obtaining 32 inputs outputs (plus 2 from I2004). Thanks to its optimized design, the I2005S8 units are powered through the control bus connected to the I2004 device. The control of the outputs is carried out through the I2004 using the proprietary Vigiplus protocol, or also through the embedded web of the device. It does not require separate power. Led indicators for diagnosis during start-up. Each unit increases the consumption of the master I2004 by max. 180 mA. Connection using plug-in strips (for 1.5 mm2 cable). Maximum switching capacity of the relays from 1 A to 30 Vdc. Dimensions 105.5 x 101 x 24 mm, anchorage by DIN rail (35 mm symmetrical). Weight 130 g. Temperature range -10 to 55ºC, non-condensing relative humidity <93%.
