Honeywell CSDA/CSDC series digital current sensors adopt digital level output, which can measure AC and DC currents. They are designed with a through-hole, and have fast response time (100μs), input-output isolation, minimum current loss, and maximum measurement current only limited by the conductor size. They are high-precision, low-cost, and with working temperature range of -25 to 85℃.
The CSDA/CSDC series are switch‑type digital current sensors with a digital level output, capable of measuring AC and DC currents. They feature a through‑hole design, 100 µs reaction time, input‑output isolation, minimal current loss, and high accuracy at low cost. The output goes low (≈0.4 V) when the measured current exceeds the actuation point, and for AC measurement the output turns off at each zero‑crossing.
The data sheet lists ordering information, electrical specifications, pin configurations, and installation dimensions for each model (e.g., CSDA1BA, CSDC1BC). Supply voltage ranges from 5 ± 0.2 V to 6‑16 VDC, with a fixed output voltage of 0.4 V and a 20 mA sink current. Temperature operation spans –25 °C to 85 °C. This manual is written in Chinese.
| Response time | 100 µs |
|---|---|
| Operating temperature range | -25 °C to 85 °C |
| Supply voltage | 6‑16 VDC |
| Output voltage | 0.4 V |
| Output current (sink) | 20 mA |
| Minimum actuation current | 0.32 A‑turn |
| Release current | 0.08 A‑turn |
The sensors have a response time of 100 µs.
They operate from 6‑16 VDC (some models use 5 ± 0.2 V).
When the measured current exceeds the actuation point, the digital output drops from Vcc to about 0.4 V.
The output voltage is fixed at 0.4 V.
