Loop Powered by the 4-20 mA signal. Use this configuration for 2-wire
transmitter only function (Figure 7).
NOTE:
If IAW is not monitored,
the SFF of the device is reduced. Reference the product FMEDA report.

DC power supply – The device is powered using the 4-20 mA signal
connections. All other outputs Safety Relay Output, SRO Status and IAW
Output function as normal.
NOTE:
The 4-20 mA analog signal is not
possible in this wiring configuration.
In this configuration the 4-20 mA output and IAW Output are monitored by the
safety system logic solver. The final element is controlled by the logic solver. Total
wire connections = 4. The 4-20mA signal is used by the logic solver to initiate
the safety function. IAW provides a separate indication of device health.
NOTE:
If IAW is not monitored, the SFF of the device is reduced. Reference the product
FMEDA report.
