Industrial CB5674POP51 Alarm Card PCB Circuit Board

The CB5674POP51 Alarm Card PCB Circuit Board from RTK Instruments is a two-channel alarm input card designed for RTK’s 725 Series annunciators, intended to be mounted in the upper card slot of the annunciator cell to provide two independent alarm inputs. In practice it works with large, medium and small window versions of the 725 Annunciator, feeding the two inputs into the panel’s status indicators and audible alert system when monitored signals cross preset conditions. The RTK 725 family specifies operation from common signal supply voltages of 24 VDC, 48 VDC or 125 VDC across its alarm cards, and CB5674POP51 is listed as the two-input variant within that voltage range. With model number CB5674POP51 and manufactured by RTK Instruments, this PCB is used to monitor two separate process signals in industrial control applications that rely on RTK’s annunciator-based alarm architecture.
