The ABB RLM01 REDUNDANCY 3BDZ000398R1 is a PROFIBUS redundant link module designed to improve the reliability of PROFIBUS networks.The following are its details:
Features
Redundant Conversion:Converts a non-redundant PROFIBUS DP line into two redundant RS485 lines,and vice versa.This ensures automatic failover to the backup link if one link fails,ensuring data continuity.
Signal Amplification and Monitoring:Amplifies the signal form and amplitude of input data and monitors the activity and error status of the three links(A,B,and M).Error indication via front-panel LEDs and signal contacts facilitates quick fault diagnosis.
Transparent Configuration:Operates transparently within the PROFIBUS network,eliminating the need to assign slave addresses and simplifying network configuration.Technical Parameters
Communication Interface:Three RS485 interfaces(A,B,and M)with transmission rates of 9.6 Kbps to 12 Mbps,using a 9-pin Sub-D connector.Electrical isolation complies with VDE 0110,with a test voltage of 500 Veff and device protection class 3.
Data telegram delay:A/B to M:1 bit time(μs)+0.6μs,M to A/B:4 bit time(μs)+0.6μs.
Power Supply:Operating voltage:24 VDC(+20%to+33 V),typical power consumption:150 mA(at 24 V),power loss:approximately 3.6 W.Connection via an 8-pin terminal block,wire cross-section:0.14-1.5 mm².Environmental Conditions:Operating temperature:0-50°C,transport/storage temperature:-30-85°C,maximum relative humidity:75%(non-condensing during operation).
Alarm Contact:Contacts open in the event of an error,switching voltage less than 60VDC,maximum switching current 1A.
Appearance:Dimensions:134x56x70mm(H x W x D),weight:330g,IP20 protection rating,mountable on a 35mm DIN rail.
Certifications:CE,UL,and CSA certified,and Germanischer Lloyd certified for use in marine and maritime systems.
Applications:Widely used in industrial control applications such as factory automation,machine control,power circuit control,power plants and substations,and oil and gas production,particularly in environments requiring high PROFIBUS network reliability.
