# RTD INPUT H1
#
Hardware and software is provided to receive signals from external Resistance Temperature Detectors and convert these
signals into a digital format for use as required. These channels are intended to be connected to any of the RTD types in
common use. Specific hardware details are contained in Chapter 3.
RTD input channels are arranged in a manner similar to CT and VT channels. The user configures individual channels with
the settings shown here.
The channels are arranged in sub-modules of two channels, numbered from 1 through 8 from top to bottom. On power-up,
the relay will automatically generate configuration settings for every channel, based on the order code, in the same general
manner that is used for CTs and VTs. Each channel is assigned a slot letter followed by the row number, 1 through 8 inclu-
sive, which is used as the channel number. The relay generates an actual value for each available input channel.
Settings are automatically generated for every channel available in the specific relay as shown above for the first channel of
a type 5C transducer module installed in slot H.
The function of the channel may be either "Enabled" or "Disabled". If "Disabled", there will not be an actual value created for
5
the channel. An alphanumeric ID is assigned to the channel; this ID will be included in the channel actual values. It is also
used to reference the channel as the input parameter to features designed to measure this type of parameter. Selecting the
type of RTD connected to the channel configures the channel.
Actions based on RTD overtemperature, such as trips or alarms, are done in conjunction with the FlexElements™ feature.
In FlexElements™, the operate level is scaled to a base of 100°C. For example, a trip level of 150°C is achieved by setting
the operate level at 1.5 pu. FlexElement™ operands are available to FlexLogic™ for further interlocking or to operate an
output contact directly.

# DCMA OUTPUT H1
#
Hardware and software is provided to generate dcmA signals that allow interfacing with external equipment. Specific hard-
ware details are contained in Chapter 3. The dcmA output channels are arranged in a manner similar to transducer input or
CT and VT channels. The user configures individual channels with the settings shown below.
The channels are arranged in sub-modules of two channels, numbered 1 through 8 from top to bottom. On power-up, the
relay automatically generates configuration settings for every channel, based on the order code, in the same manner used
for CTs and VTs. Each channel is assigned a slot letter followed by the row number, 1 through 8 inclusive, which is used as
the channel number.
Both the output range and a signal driving a given output are user-programmable via the following settings menu (an exam-
ple for channel M5 is shown).
