Two-channel pulse/counter data logger for counting switch-contact closures or DC logic pulses. Each channel supports a “slow” (2 ms) or “fast” (10 µs) input and records up to 4,095 counts per sample interval. Accepts dry-contact switches or logic levels (Low 0–0.5 V, High 4.5–24 V), with a maximum signal frequency of 100 kHz. Available in 32 KB or 128 KB memory versions. Powered by a 3.6 V lithium battery; works with TrendReader software for Windows.
