Temperature Acquisition Module ASDCM-8W
- Commodity name： Temperature Acquisition Module ASDCM-8W
Product Details
- Product Description
-
Performance Overview
The industrial‑grade isolated temperature acquisition module complies with the standard MODBUS‑RTU communication protocol. Internally, it features a 24‑bit ADC and an advanced smart processor, supporting a wide range of configuration software and PLC systems. It is suitable for various temperature‑acquisition applications and accommodates multiple types of temperature sensors. The device operates on a DC input voltage of 9–32 V, mounts on a standard DIN rail, and incorporates opto‑isolation between the communication interface unit and the temperature‑acquisition unit. Additionally, the communication interface is designed to provide protection against electrostatic discharge and surge voltages.
Technical Specifications
1. Input signal:
- 8-channel temperature:
- Resistance temperature detectors: Pt100, Cu50;
- Thermocouples: K, E, S, T, B, J, R, N; Internal compensation accuracy of thermocouples: ±1°C
- Accuracy 0.1%
2. Temperature measurement sampling rate:
- 20 sps (typical value)
3. Communication Interface:
- Physical Layer: RS485
