Emerson SS4303T01 KL3021X1-LS1 Safe Analog Input Module
SS4303T01 KL3021X1-LS1 is an LS-CARM safety type analog input module of Emerson DeltaV SIS system, used for safety instrument system SIS, receiving 4-20mA analog signals from field transmitters, and supporting HART protocol communication to read device diagnostic information.

SS4303T01 completes analog signal acquisition, signal conversion, and safety diagnosis. It uploads on-site process signals to the SIS logic solver to achieve safety monitoring of process parameters such as pressure, liquid level, temperature, and flow rate; SS4303T01 cooperates with SIS logic to implement safety interlock protection. When the process parameters exceed the limit, safety shutdown and interlock actions are triggered to meet SIL3 safety level requirements and ensure the safe operation of the process equipment.
The module needs to be used with a CHARM base plate, which belongs to the electronic grouping I/O architecture, to achieve the collection and diagnosis of safe I/O signals.

Product features
- 1SIL3 safety level certification: compliant with IEC61508 standard, designed specifically for DeltaV SIS safety instrumented systems, can be used for safety interlock parking circuits, and meets the safety functional requirements of chemical and petrochemical industries.
- 8-channel 4-20mA+HART: 8-channel analog input channel, supports 4-20mA transmitters, and also supports HART protocol to read the status and fault diagnosis information of on-site instrument equipment, and identify instrument abnormalities in advance.
- Channel electrical isolation: Each channel is electrically isolated from the system side to suppress on-site interference, avoid surge damage to the system, and improve signal reliability.
- Built in complete self diagnosis: The module comes with hardware diagnosis to detect channel open circuits, short circuits, and signal abnormalities. Fault information is uploaded to the SIS system for easy fault location.
- CHARM electronic grouping architecture: modular plug-in design, installed on the CHARM motherboard, supports hot swapping, on-site module replacement does not require power outage, reducing downtime.
- Safety circuit adaptation: Adapt to the SIS logic solver CSLS, directly participate in safety logic operations, and achieve process over limit safety interlocking.
