Trumeter’s 7400 series electronic adding/subtracting counter with an 8 digit display has been designed for minimal power requirement, ideally suited for PCB board mounting and use in low power or battery powered applications (Typical external battery life of 10 years can be achieved based on 1/2 AA 900mAH 3V Lithium battery). The Trumeter 7400 is capable of up to 10kHz count input frequencies, both versions incorporate a contact closure count reset as standard, however, version 7401AS has no front button reset ideally suited to lifetime monitoring applications or where tampering could be an issue. Bi-directional counting is possible with this product - the direction input terminal when active allows the count “adding input” to become the “subtracting input”. These counters are CE, UL and cUL approved.
