Analog Data Acquisition Module ASDCM-8A
- Commodity name： Analog Data Acquisition Module ASDCM-8A
Product Details
- Product Description
-
Performance Overview
The industrial‑grade isolated analog signal acquisition module complies with the standard MODBUS‑RTU communication protocol. Internally, it features a 16‑bit ADC and an advanced intelligent processor, supporting a wide range of configuration software and PLC systems. It is suitable for various voltage and current acquisition applications and allows independent configuration of multiple measurement ranges. The device operates on a DC input voltage of 9–32 V, mounts on a standard DIN rail, and employs opto‑isolation between its communication interface and analog channels. Additionally, the communication interface incorporates ESD and surge protection.
Technical Specifications
1. Input signal:
- 8-channel AI: Signal ranges include DC 4–20 mA, –20 mA to 20 mA, 0–5 V, –5 V to 5 V, 0–10 V, and –10 V to 10 V, with an accuracy of 0.05%.
2. Analog signal sampling rate: 15 samples per second (typical value);
3. Analog Input Impedance:
- Voltage: 1.1 MΩ;
- Current: 100 Ω;
4. Communication Interface:
- Physical Layer: RS485
- Baud rate: Default is 9600 bps; it can also be configured to 2400 bps, 4800 bps, 19200 bps, 38400 bps, 57600 bps, or 115200 bps.
- Protocol: MODBUS-RTU
- Communication distance: ≤1000m C
5. Status indicator light:
- PWR: Power indicator; remains steadily lit when the module is operating normally.
- TXD: Master station communication status indicator; the light flashes during normal communication.
- RXD: Device communication status indicator; the light flashes during normal communication.
- CH1–CH8: Signal status indicator; remains steadily lit when the analog signal exceeds the set range.
6. Dielectric Strength: 1500 V AC (between the analog input, the RS485 communication interface, and the power supply; leakage current ≤ 1 mA)
7. Electromagnetic Compatibility: EMC complies with IEC 61326-3-1.
8. Power Consumption: Less than 1 W when powered by 24 V DC.
9. Supply voltage range: 9 V DC to 32 V DC
10. Operating temperature: -20°C to +60°C
