The I2005S8 is an expander module with 8 digital outputs using relay contacts for the I2004 interface. Up to 4 I2005S8 can be linked for each I2004, resulting in 32 inputs and outputs (plus 2 from the 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 device's embedded web. Does not require independent power. Led indicators for diagnosis during start-up. Each unit increases the consumption of the master I2004 by max. 180mA. Connection using plug-in strips (for 1.5 mm2 cable). Maximum switching capacity of the relays of 1 A at 30 Vdc. Dimensions 105.5 x 101 x 24 mm, anchoring via DIN rail (35 mm symmetrical). Weight 130g. Temperature range -10 to 55ºC, relative humidity without condensation < 93%.
