Remote Type Surge Counter: PH312-068

Remote controlled Surge Counter detects lightning surges by a current sensor and transfers data to your office PC through RS232C. The data is the peak current value, the current polarity and the time. The data is also stored within the built-in memory.
Additional unit: PH312-067 gives you relay contact output signal directly as metal signal. Signal can be either A contact or B contact.
