The Emerson KJ2231X1-EA1 is a Safety Integrity Systems (SIS) relay module designed for safety-critical applications.With redundant components, improve system reliability.The SIS Relay module can be used with DeltaV SIS to switch up to 2.5A at 250V AC for safety applications. It opens contacts for field power when de-energized. The SIS Relay module contains three relays from different manufacturers.

In general, DeltaV SIS™ will be connected to 4-20 mA analog signal devices or discrete I/O devices rated up to 500 mA per channel. However, there will be some output signals that require higher currents, and in some applications a non-combustion output is required. For applications that require only high currents, DeltaV solutions offer SIS relay modules. For applications that need to limit the current of a final device with a non-combustion rating, there are current limiter modules. Use the RC compensator module to ensure proper field wiring monitoring when using inductive loads. The use of SLS wire end modules ensures proper field wiring monitoring when using discrete switches.

Usage Scenarios

This device would typically be used in:

Safety-critical industrial processes 

Applications requiring SIL-rated components 

Systems where safety instrumented functions are implemented

Benefits

The SLS terminal resistance module can diagnose the field wiring connected to the discrete input terminal device

R-C compensator module can diagnose the field wiring of high inductance discrete output terminal equipment

The voltage monitor meets the requirements of SIL3 applications for higher voltage discrete inputs

SIS relays provide higher current and voltage ratings for discrete outputs to meet SIL3 application requirements

The SIS current limiter module enables the discrete output to be non-flammable, meeting non-flammable installation requirements

It can better adapt to different field wiring situations and application requirements.
