Remote Terminals
Section 5-1
The following graphs show the characteristics for G3DZ-2R6PL Relays
installed in SRT1-ROF08 and SRT1-ROF16 Relay-mounted Remote Termi-
nals.
Slave Components
The following diagram shows the main components of the Relay-mounted
Remote Terminals. The functions of these components are described below.

Non-repetitive (Keep the inrush
current to half the rated value if it
occurs repetitively.)

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 setting (SRT2 Series)
or Reserved (Always OFF) (SRT1 Series)
Pins 3 to 6: Node number setting
Mounting Screw Holes
Used when screwing the Unit to a control panel.
Terminal Block
Connect the CompoBus/S communications cable,
communications power supply (including the power
supply for the outputs), and output devices such as
lamps and solenoids to the terminal block.
CompoBus/S Indicators
Indicate the status of the Slave and communications.
Power Relays or Power MOS FET Relays
These are the power relays (SRT
(
-ROC08 and
SRT
(
-ROC16) or power MOS FET relays
(SRT
(
-ROF08 and SRT
(
-ROF16). There are 8
in the 8-output Relay-mounted Remote Termi-
nals and 16 in the 16-output Relay-mounted
Remote Terminals. The relays can be replaced.
DIN Track Mounting Hook
Used when mounting the Unit to a DIN track.
Relay Removal Tool
Use this tool when removing power relays or power MOS FET
relays. Remove the tool from the Relay-mounted Remote Termi-
nal by pulling it away from the Unit.
