MICO 4.6 is a 4-channel electronic auxiliary circuit switch and serves as current monitoring. The operating voltage (+24V DC/at least 10A) is split into 4 current monitored load circuits (channels). When engaging the operating voltage the switched-on channels are time-delay activated (time-delay of each channel = 75 ms) to avoid overload current. The current selector switches (1) enable an independent setting of the operating currents of 1A, 2A, 4A or 6A (see disconnecting characteristic). When exceeding the operating current the corresponding channel will be disconnected pursuant to the disconnecting characteristic. In the event of voltage dip or power failure the current operating condition will be saved and reestablished after the recovery of the supply voltage. The setting of the current range during operation leads to the disconnection of the channel. It may only be switched on manually. Each channel may be manually connected or disconnected through the buttons (2). The current operating condition is signalised by the LED (2) – (red/green, see displays). All channels disconnected due to overload may be activated through ON (restart) (3) – see restart. In addition, the module is provided with a potential-free message output (4) to establish a summation message (see summation message). A bridging concept permits the lining-up of multiple modules (maximum operating current 40A) without wiring. For this purpose a bridging set is available as an option (see bridging set).
