ABB IMSPM01 Serial Port Module
Product Description
A dedicated serial communication module for ABB industrial systems (AC 800M, Symphony Plus), linking controllers with serial field devices (transmitters, inverters, HMIs) via standard protocols. Optimized for point-to-point/multi-drop communication, bridging digital/analog I/O and Ethernet gaps.
Key Specifications
- Serial Ports: 2 independent RS-485 (half-duplex); RS-232 compatible via external adapters.
- Protocols: Modbus RTU (master/slave), ABB DriveCom, custom configurable.
- Comm Params: Baud rate 1200-115200bps; data bits (7/8), stop bits (1/2), parity (none/odd/even) adjustable.
- Power: 24V DC (18-30V DC); ≤3W full load.
- Environment: -40°C to +70°C; 5%-95% humidity (non-condensing); IP20.
- Mechanical: 35mm DIN rail; 90×75×22mm; fits ABB I/O racks.
- Protection: 2.5kV AC isolation (serial ports-backplane); ±8kV ESD (IEC 61000-4-2).
- Catalog Nos.: GJR5252000R0001, GJR5252000R0002 (regional variations).
Advantages & Features
- Dual RS-485 ports for simultaneous multi-device connection, no interference.
- Multi-protocol support for seamless ABB/third-party device integration.
- Isolation+ESD protection for stable transmission in harsh environments.
- Online config via ABB Control Builder M; built-in diagnostics for quick troubleshooting.
- Compact design saves cabinet space; unified installation with ABB modules.
Application Fields
- Drive Control: Connect ABB ACS inverters (RS-485/Modbus RTU) for remote speed adjustment and status monitoring.
- Process Monitoring: Link serial transmitters (temp/pH/flow) to DCS for real-time data collection.
- Local Operation: Connect HMIs to controllers for on-site status viewing and manual commands.
- Legacy Integration: Upgrade old serial devices into new ABB systems, avoiding replacement costs.
Precautions
- Use shielded twisted-pair (0.5-1.0mm²) for RS-485; single-point ground shield. Add 120Ω resistors at multi-drop bus ends.
- Match module protocol mode (master/slave) to devices; avoid duplicate addresses in RS-485 bus.
- Use regulated 24V DC power (overload protection); no power-on before wiring; check polarity.
- Avoid direct sunlight, high humidity (>95% non-condensing), corrosive gas; keep away from heat sources.
- Regularly check indicators; clean dust every 3-6 months. Replace with same/compatible models; reconfigure params post-replacement.
