AEG AM-S980-810
Product Type: Precision Analog Signal Amplifier and Conditioner
Product Overview:
The AEG AM-S980-810 is a precision analog signal amplifier module designed for conditioning low-level sensor signals (mV, mA) to standard industrial ranges (0–10 V, 4–20 mA) before transmission to the controller.
Detailed content
Technical Specifications:
- Input Signal Types: mV (± 50 mV), mA (0–20 mA), V (0–5 V)

- Dimensions: 90 mm x 60 mm x 40 mm
- Weight: 150 g
Material Composition:
- Housing: Aluminum alloy 6063-T5, silver anodized
- Amplifier IC: Analog Devices AD620 or TI INA128 (instrumentation amplifier)
- Isolation: Analog Devices AD202 (isolation amplifier), 5 kV rating
- Terminals: Gold-plated phosphor bronze spring contacts
Structural Features:
- DIN rail mountable (35 mm)
- 4 DIP switches for gain and output range selection
- Trimmer potentiometer for zero offset adjustment
- LED indicators: Power, Signal, Fault
Working Principle:
The input signal is amplified by a precision instrumentation amplifier (AD620) with gain set by an external resistor (or internal DIP-selected gain network). The amplified signal is then isolated via an isolation amplifier (AD202) and converted to the selected output range (0–10 V or 4–20 mA) using a voltage-to-current converter (XTR115 or equivalent).
Key Advantages:
- Ultra-high accuracy (± 0.1% FS) for precision measurement
- Programmable gain (1–1000) covers all common sensor types
- 1500 V DC isolation for safe signal transmission
- Zero and span trimmers for field calibration
Applicable Industries:
Laboratory instrumentation, precision weighing, strain gauge measurement, temperature monitoring (RTD/TC), pressure transducers.
Installation Requirements:
- Mount on 35 mm DIN rail
- Set DIP switches for correct gain and output range before connecting
- Use shielded twisted-pair cable for mV-level inputs
- Calibrate zero offset using on-board trimmer before commissioning
Usage Precautions:
- Do not apply input voltage exceeding 5 V DC to mV input range
- For mV inputs, use 3-wire connection to cancel lead resistance
- Do not exceed 1500 V DC between input and output (isolation limit)
- Recalibrate annually or after any mechanical shock
