3AFE61320946P0001 LDMUI-01
Product Name: ABB LDMUI-01 Loop Power Supply Universal Measurement Interface
Brand: ABB
Series: LD Series Universal Measurement/I/O Module
Product type: Pocket sized circuit power supply universal measurement interface, used to convert on-site sensor signals into isolated digital quantities that can be read by PLC
ABB 3AFE61320946P0001 LDMUI-01
Core function: Convert various sensor signals such as 4-20mA, ± 10V, 0-1V, Pt100/Pt1000, thermocouple J/K/T/E/N into 16 bit high-precision isolated digital values, and upload them to the control system through Modbus RTU (RS-485) or optional 4-20mA retransmission. No additional I/O rack is required, no separate 24V power supply is needed, and the self consumption current in loop power supply mode is less than 1mA.
Input channel: 4-20mA/± 10V/0-1V/Pt100 or Pt1000/thermocouple J, K, T, E, N type, selected by rotating code, no jumper or firmware change required
Measurement accuracy: Voltage range ± 0.1%, thermocouple range ± 0.2%, automatic cold end compensation, accuracy ± 0.5 ° C
Resolution: 16 bits (0.0015%)
Signal isolation: 2.5 kV, three port isolation (between sensors, power supply, and bus)
Filtering: 3-pole low-pass filtering, 50/60 Hz suppression, power supply noise suppression to below 0.05%
Communication interface: Modbus RTU (RS-485), optional 4-20mA signal retransmission
Power supply method: Loop power supply (<1mA), or 24V DC ± 20%, power consumption 0.8W
Working temperature: -40 ° C to+70 ° C
Protection level: IP67 (some data indicate IP65)
Installation method: 35mm DIN rail installation
Size: 22.5mm x 99mm x 115mm (width x height x depth)
Weight: Approximately 0.15kg
Certification: CE, UL 508, IEC 61131-2, RoHS, DNV-GL for marine use
MTBF: Over 300 years (Telcordia standard), with a 10-year on-site data return rate of less than 0.05%
