Output status at CPU failure and hardware error is –5%, 3.2 mA or less.
NAMUR NE43 compliant * 1
Output signal limits:
3.8 mA to 20.5 mA
Failure alarm down-scale: output status at CPU failure and
hardware error is –5%, 3.2 mA or less.
Failure alarm up-scale: output status at CPU failure and
hardware error is 110%, 21.6 mA or more.
* 1: Applicable for Output signal code D and E. The hardware error indicates faulty amplifier or
capsule. When combining with Optional code F1, output status for down-scale is –2.5%,
3.6 mA DC or less.
* 2: Applicable for Output signal code D and E. Write protection switch is attached for Output code E.
