Monitors events and analog signals at 100 pulses per second (100Hz) and records the total count with a time and date stamp at user-programmed intervals. Can be used with dry contact switches and relays or analog voltage input signals from external devices (i.e. pulse initiators, pulse output transducers, totalizers, counters, flow meters etc.) Perfect for applications where fast data sampling and recording is required. Features user-programmable Engineering Units with MadgeTech software. Screw terminal input. 10-Year Battery.
