In most cases, DeltaV SIS™ will connect to either 4 - 20 mA analog signal devices or discrete I/O devices rated at up to 500 mA per channel. However, there will be some output signals that require higher currents and in some applications non-incendive outputs are required. For applications that simply need high current, the DeltaV solution offers the VS6907 SIS Relay module. For applications where the current to the final device needs to be limited for non-incendive ratings, there is the current limiter module. Using the RC compensator module ensures that the monitoring of field wiring is performed correctly when using inductive loads. Using the SLS End of Line module ensures that monitoring of field wiring is performed correctly when using discrete switches.
