Slave Components The following diagram shows the main components of the SRT2-OD08 Transistor
Remote Terminal. The functions of these components are described
below.
DIP Switch
Open the cover to reveal the DIP switch. The DIP switch's
pins have the following functions:
Pin 1: Hold/clear outputs for communications error
Pin 2: Communications mode setting (SRT2 Series)
or Reserved (Always OFF) (SRT1 Series)
Pins 3 to 6: Node number setting
CompoBus/S Indicators
Indicate the status of the Slave and communications.
Mounting Screw Holes
Used when screwing the Unit to a control panel.
DIN Track Mounting Hook
Used when mounting the Unit to a DIN track.
Terminal Block
Connect the CompoBus/S communications cable, communications
power supply, I/O power supply, and output devices such as relays
and indicators to the terminal block.
Output Indicators
Indicate the status of each contact.
(Lit when the output is ON.)
The SRT-OD04 and SRT-OD04-1 have 4 indicators,
the SRT-OD08 and SRT-OD08-1 have 8 indicators, and
the SRT-OD16 and SRT-OD16-1 have 16 indicators.
