External option modules
8.6.1.
External input / output module
The relay supports also external input / output modules used to
extend the number of digital inputs and outputs. Other
modules have analogue inputs and outputs.
The following types of devices are supported:
Analog input modules (RTD)
Analog output modules (mA-output)
Binary input/output modules
EXTENSION port is primarily designed for I/O modules. The
relay must have a communication option card with
EXTENSION port. Depending of the option card I/O devices
may require an adapter to be able to connect to the port (i.e.
VSE004).
NOTE! If External I/O protocol is not selected to any communication port,
VAMPSET doesn’t display the menus required for configuring the I/O
devices. After changing EXTENSION port protocol to External I/O, restart
the relay and read all settings with VAMPSET.
