Remote Terminals
Section 5-1
Note
The current consumption is the value with all 4 and 8 and 16 points turned ON
excluding the current consumption of the external sensor connected to the
input Remote Terminal and the current consumption of the load connected to
the output Remote Terminal.
Input Specifications
Slave Components
The following diagram shows the main components of the SRT2-ID08 Transis-
tor Remote Terminal. The functions of these components are described
below.
Node number settings
The node number is set on a DIP switch. (Set the node
number before turning on the Slave.)
