A signal converter (or transmitter) is a device used in industrial and process automation to translate one electrical signal type into another, such as mV, RTD, thermocouple, resistance or voltage inputs into standard process outputs like 4‑20 mA or 0‑10 V. They often include linearisation, filtering, and signal conditioning to ensure accurate, reliable transmission across PLCs, control systems or data acquisition hardware amelec-uk.comamelec-uk.com.
Why Choose Amelec’s Signal Converters?
• Universal Inputs & Flexible Outputs
Amelec converters support a wide range of sensors—RTD (PT100/PT1000), thermocouple, mV, resistance, voltage, or loop-powered signals—and output configurable current or voltage loops suitable for most automation systems amelec-uk.com.
• High Accuracy & Isolation
For example, the ADM213 mV Signal Converter/Isolator delivers <±0.1 % span linearity, fast response (<100 ms), and provides 1 kV rms galvanic isolation between input, output, supply and earth — essential for high-integrity data in noisy environments amelec-uk.com+1amelec-uk.com+1.
• Safety-Certified & Rugged Design
Products like the ADM221 Dual‑Output RTD Transmitter are suitable for SIL 1 and SIL 2 Safety Instrumented Systems (IEC 61508), mounted in robust polycarbonate enclosures with a 10-year warranty amelec-uk.com+3amelec-uk.com+3amelec-uk.com+3.
• DIN-Rail or Surface Mountable
These transmitters are compact and versatile with DIN-rail (TS35) or surface mounting options—ideal for panel build-outs or retrofits in control cabinets amelec-uk.com+2amelec-uk.com+2amelec-uk.com+2.
• Customisable & Field-Testable Options
Models like the ADM213 offer RFI protection, input jack for proof testing, 3½‑digit display options, bi‑polar I/O or custom special ranges, making them highly adaptable to specific field requirements amelec-uk.com.
