1. Product Identification & Overview

️· Product: LCS2 Signal Conditioner/Transmitter (likely for load cells or bridge-based sensors)
️· Manufacturer: M-System (www.m-system.co.jp)
️· Function: It takes input from load cells (or similar bridge-based sensors) and converts it into a standard output signal. This often involves amplification, filtering, and signal conditioning.

2. Technical Specifications & Features

️· Input:
- Bridge voltage input from load cells.
- Rated output from strain gauge: 1 – 20 mV/V
- Input must be over 3 mV.
- Allowable leadwire resistance: ≤ Total Strain Gauge Resistance × 0.25
️· Excitation: Adjustable, 2 – 5V DC (5V default). Provides power to the load cell.
️· Span Adjustment: 100 – 20% (front panel adjustment)
️· Zero Adjustment: 0 – 80% (front panel adjustment)
️· Display: LCD digital display, showing input as a percentage (0.0 - 100.0%, minimum digit 0.1%).
️· Output:
- DC Current: 0 – 20 mA (minimum span: 1 mA)
- DC Voltage: -10 – +12 V DC (minimum span: 5 mV)
■ Output drive capability for voltage output: 10mA maximum; 5mA for negative voltage output; at >= 0.5 V
️· Power Requirements:
- AC: Rating ±10%, 50/60 Hz, approx. 5 VA
- DC: 24 V ±10%, approx. 150 mA, ripple ≤ 10%
️· Operating Environment:
- Temperature: -5 to +60°C (23 to 140°F)
- Humidity: 30 to 90% RH (non-condensing)
️· Mounting: Surface or DIN rail
️· Weight: 430 g (0.95 lb)

3. Performance Characteristics

️· Accuracy: ±0.1% of full scale (input ≥ 3 mV).
️· Temperature Coefficient: ±0.015%/°C (±0.008%/°F) (input ≥ 3 mV). This indicates how much the output changes with temperature variations.
️· Line Voltage Effect: ±0.1% over the specified voltage range.
️· Insulation Resistance: ≥ 100 MΩ with 500 V DC.
️· Dielectric Strength: 2000 V AC (AC power input to output); 1000 V AC (DC power input to output); 2000 V AC (input to output)
