Emerson Automation Solutions’ latest KJ2201X1-JA1 is an SLS redundant terminal module designed for hazardous atmospheres and compliant with ATEX and IECEx standards, ensuring its safe use in potentially explosive environments. The module has powerful power specifications with input power of 30 VDC and current up to 30 mA per channel, up to 1 A per channel when the circuit is between terminals A and B and 1 A when it is between terminals A and C.

The KJ2201X1-JA1 also has excellent environmental tolerance, operating stably at ambient temperatures from -40°C to +70°C, and can withstand half sine wave shocks up to 10 g and peak-to-peak vibrations of 1 mm from 2 to 13.2 Hz, and vibrations of 0.7 g from 13.2 to 150 Hz. In addition, the module is compliant with ISA-S71.04-1985 Airborne Contaminants Class G3, suitable for environments with specific levels of air contaminants, while maintaining stable performance at 5 to 95% noncondensing relative humidity.
