5.3 Setting Inputs for use with 48VDC
As an option RTK 725B systems can be supplied with each 4 channel alarm card suitable for
use with 48VDC signal inputs.
5.4 Setting Inputs for use with 48VAC
RTK 725B signal inputs are bi-polar and therefore suitable for use with 48VAC.
However when using AC inputs additional filters are added which result in a 25mS response
time before the alarm activates.
In systems using Time Stamping the alarm would still indicate the time the alarm first occurred
to the millisecond.
To set the signal supply voltage on each input to either 48VDC or 48VAC, a drop-down menu is
provided in the Configuration Software. Selection is made under the Input tab using the drop-
down menu labelled “Field Contact Voltage (V)”
The settings are available on the following (4) channel alarm cards
