Technical Specifications:

Input Signal: 4–20 mA DC / 1–5 V DC / 0–10 V DC (selectable via DIP switch)
Output Signal: 4–20 mA DC / 1–5 V DC / 0–10 V DC (selectable via DIP switch)
Power Supply Voltage: 24 VDC (±10%)
Accuracy: ±0.1% of span
Temperature Drift: ±0.005%/°C
Insulation: Triple isolation (input / output / power supply)
Insulation Resistance: ≥100 MΩ at 500 VDC
Dielectric Strength: 1500 VAC for 1 minute
Operating Temperature: -10°C to +55°C
Response Time: ≤100 ms (typical)
Mounting: 35 mm DIN rail (EN 50022)
Width: 22.5 mm

Functional Features:

Universal input/output — accepts and outputs current or voltage signals
Triple galvanic isolation — input, output, and power are fully isolated
No communication function (standalone operation)
Process recording support (PR) — compatible with SCADA recording systems
DIP switch configuration for input/output type selection
Zero and span adjustment via front-panel potentiometers

Material Composition:

Housing: Flame-retardant polycarbonate/ABS blend (UL94 V-0)
Terminal Blocks: Phosphor bronze, tin-plated
PCB: Conformal-coated epoxy glass

Structural Characteristics:

Dimensions: 22.5 mm × 90 mm × 112.5 mm (W × H × D)
Terminal Type: T1 screw clamp terminals (AWG 22–12)
Weight: Approximately 150 g

Working Principle:
The SC4A accepts an analog input signal (current or voltage), conditions it through precision signal conditioning circuitry, and outputs a proportional isolated analog signal. The triple isolation barrier uses transformer/optocoupler technology to ensure complete electrical separation between input, output, and power circuits.

Key Advantages:

±0.1% high accuracy — superior to most competitors
Triple isolation eliminates all ground loop issues
Universal I/O — one device replaces multiple converter types
Front-panel adjustment — zero and span accessible without removing from panel
