Actuate Relay 4CH

the scalae relay 4ch expands our automation product range a differential feature of the scalae 4ch is the onboard power supply, which enables the board to be powered by an ac power source, i e the pcb can be directly powered from a transformer alternatively, a dc power source can be used scalae relay the key aspects of the scalae relay are listed below \ it's designed to be fitted into a din rail enclosure \ edge connectors make all connections to the pcb \ power connection more reliable scalae features the scalae 3ch includes the following features feature description power supply dc | ac opto coupled inputs 4 relay outputs 4 input 1 is directly coupled to output 1, etc product application the 4 channell board is ideal for smaller scale applications where the mcu or system does not need to connect to more than 4 high powered devices if more than 8 i/o is required, the docid\ gtaubdglmeuahi2qwqiuj would provide expanded i/o capability, or two 4 channel pcbs can be used, depending on the requirements
