Description
The S-S-Bus coupler module is a device for the collec-
tion of S pulses. With this module the consumption
data of any measurement device with a S output
becomes bus capable and can be accessed by every
Saia PCD® or Energy Manager through the S-Bus.
The addressing of 00 to 99 and the identication of
the module will be done with the two rotary switches
(×1 / ×10) on the front side. Up to 100 S-S bus coupler
modules can be connected on the same bus
simultaneously.

Important instructions
Safety
Check compliance with nominal voltage before commis-
sioning the device (see type label). Check that connection
cables are free from damage and that, when wiring up the
device, they are not connected to voltage.
Cleaning
Modules can be cleaned with a dry cloth, or a cloth
moistened with a soap solution. Never use corrosive
substances, or products containing solvents.
Maintenance
S-S-BUS modules are maintenance-free. If damaged
during transportation or storage, no repairs should be
undertaken by the user.
Guarantee
Opening the module invalidates the guarantee.
Switch for line termination resistors (Pic. 2)
If the S-Bus module is used in the S-Bus as last device,
then the sliding switch “RS-485 Terminate” need to be in
position “On”.
