5.8 TRANSDUCER I/O
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 the HARDWARE chapter.
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 below for the first channel of
a type 5C transducer module installed in slot M.
RTD INPUT M5
The function of the channel may be either "Enabled" or "Disabled." If Disabled, there will not be an actual value created for
the channel. An alphanumeric "ID" is assigned to the channel - this ID will be included in the display of the channel actual
value. This ID 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.
