SPIIT13 ABB – Signal Isolator and Interface Transmitter
Product Overview
The SPIIT13 ABB is a compact and versatile signal isolator designed to ensure reliable signal transmission and electrical isolation in industrial automation systems. Part of ABB’s SensoPart series, this device protects sensitive control circuits from ground loops, noise, and voltage surges, making it ideal for use in process industries, power plants, and factory automation. Its modular design and easy configuration simplify integration into existing systems while enhancing signal integrity.
Key Features
- Universal Signal Conditioning
- Accepts inputs from thermocouples, RTDs, mA/VDC signals, and frequency signals.
- Converts signals to standardized outputs (4–20 mA, 0–10 V DC) for PLCs, DCS, or SCADA systems.
- High Electrical Isolation
- 1500 V AC galvanic isolation between input, output, and power supply to prevent ground loops and interference.
- Compliant with IEC 61010 safety standards for hazardous environments.
- Compact and Flexible Installation
- DIN rail mounting (35 mm) with space-saving design for dense control panels.
- Transparent terminal covers for easy wiring and maintenance.
- Diagnostic Capabilities
- LED status indicators for power, input, and output signals.
- Auto-diagnostics for fault detection (open sensor, overload, etc.).
- Wide Power Supply Range
- Operates on 24 V DC (±10%) or 100–240 V AC (universal power input).
- Low power consumption (<2 W) for energy-efficient operation.
- EMC Resilience
- Robust immunity to electromagnetic interference (EN 61326-1).
- Surge protection up to 1 kV on input/output lines.
