Emerson KJ2221X1-BA1 SIS Net Repeater Module
The Emerson KJ2221X1-BA1 SISNet Repeater Module serves as a dedicated communication component within Emerson DeltaV Safety Instrumented Systems (SIS). It regenerates and repeats SISNet communication signals across extended network segments, ensuring signal integrity and reliable message delivery between distributed safety controllers and remote nodes.
Network Communication and Signal Extension
This module is purpose-built to maintain network performance over long distances within safety-critical architectures. By isolating and boosting communication signals, it prevents data degradation caused by line attenuation or electrical noise, supporting stable data exchange across large plant layouts.
Environmental and Power Specifications
Operating on a 24 VDC input voltage with a maximum current consumption of 300 mA, the unit is engineered for continuous performance in harsh environments. It functions within an ambient temperature range of -40 deg C to +70 deg C and accommodates relative humidity levels from 5% to 95% non-condensing. The hardware complies with ISA-S71.04-1985 Class G3 standards for airborne contaminant resistance.
Physical Dimensions and Mechanical Resilience
The module is housed in a compact physical footprint measuring 16 cm x 16 cm x 12 cm and weighs 0.8 kg. It is constructed to withstand severe mechanical stress, featuring shock resistance rated at 10 g for an 11 ms half-sine wave, alongside vibration resistance of 1 mm peak-to-peak from 2 Hz to 13.2 Hz and 0.7 g from 13.2 Hz to 150 Hz.
