HYPOT-15 PLC Ready Output Option

The PLC Ready Output option creates a signal that acts as an instrument power-on indicator. The signal is available through the Remote I/O output connector which is located on the back of the instrument. This option closes the relay contact between pin (1) and pin (2) on the output connector once the instrument is powered on. The PLC Ready Output signal replaces the Pass signal that is present on the standard instrument.

It should be noted that the term “Ready” in “PLC Ready Output” only implies that the instrument is powered on. To perform a test, it should be verified that an interlock device is used or the interlock disable connector that was provided with the instrument is installed, and that there are no failure indicators active on the instrument. For more information on the Remote I/O signals/ connections and Remote Interlock refer to section Using Remote I/O and PLC Control.
