SH2RE16A4, Relay Output Module, SH2RE16A4, SH2RE16A4 is a four-relay output module for DIN rail mounting. When the Dupline® bus receives an activation command, the output is activated and remains activated until the deactivation order is received. Thanks to the internal bus, the SH2RE16A4 modules can be connected to each other without the need for wiring on the Dupline bus., SH2RE16A4, If the SH2RE16A4 is connected to the Dupline bus® and the bus is working properly, the relay module will be in STANDARD mode and the green LED will be activated. The relay will access local mode if the button is pressed. In LOCAL mode, the relay does not support any bus command and the LED will flash. The relay can return to STANDARD mode after one of the following events: 1) After a time limit of 1 minute after pressing a button 2) After restarting the power. If the bus is not connected or fails, the module will not receive power and the outputs will maintain the last state they had. There is no safe status present in case of failure. To achieve reduced power consumption, the 4 outputs are not all activated at the same time, but a delay of 500ms occurs between each activation.
