RS485 Repeater ASDCM-2R
- Commodity name： RS485 Repeater ASDCM-2R
Product Details
- Product Description
-
Function Description
It accepts signals from temperature sensors such as thermocouples and resistance temperature detectors, performs internal filtering and noise suppression, processes the data, and converts the output into an isolated RS‑485 communication signal (Modbus RTU protocol). It achieves three‑terminal isolation among input, output, and power supply.
Product Features
● Three-terminal isolation for input, output, and power supply
● High-efficiency switching power supply
● Port Protection
● Low-power design
● Sensor fault diagnosis function
Panel Description
Green indicator light: Power indicator light
Technical Specifications
- Power supply: 18 VDC to 30 VDC
- Maximum power consumption: 1.3 W
- Input signals: RTD measurements such as Pt100, Cu50, K, E, S, T, B, J, R, N; excitation current approximately 1 mA; lead resistance < 20 Ω per wire.
- TC measurement: Cold-junction compensation accuracy ±2°C; Wiring diagram—output signal: RS485.
- Baud rate: 2400 bps to 115,200 bps (configurable)
- Transmission accuracy: For ranges ≥200°C, ±0.05% F.S. (at 25°C ± 2°C); for ranges <200°C, ±0.1°C (at 25°C ± 2°C).
- Temperature Drift: 25 ppm/°C
- Response time: approximately 500 ms (10%–90%)
- Electromagnetic Compatibility: Complies with GB/T 18268 (IEC 61326-1)
- Dielectric strength: ≥1500 V AC; 1 min (between input, output, and power supply)
- Insulation resistance: ≥100 MΩ (500 V DC)
- Operating temperature: -20°C to 60°C
- Product dimensions: 17.5 mm × 108.5 mm × 114 mm (width × height × depth)
- Product weight: approximately 180 g
- Installation method: DIN standard rail (35 mm)
