Deployment of ELPRO products in customer environment

There is increasing concern regarding cybersecurity across industries, where companies are steadily integrating field

devices into enterprise-wide information systems. This is why ELPRO has incorporated secure development life cycle

in their product development to ensure that cybersecurity is addressed at all levels of development and

commissioning of our products.

There is no protection method that is completely secure. Industrial Control Systems continue to be the target for

attacks. The complexities of these attacks make it very difficult to have a complete secure system. A defence

mechanism that is effective today may not be effective tomorrow as the ways and means of cyber-attacks constantly

change. Therefore, it’s critical that our customers remain aware of changes in cybersecurity and continue to work to

prevent any potential vulnerability of their products and systems in their environment.

At ELPRO we are focusing on analysing emerging threats and ensuring that we are developing secure products and

helping our customers deploy and maintain our solutions in a secure environment. We continue to evaluate

cybersecurity updates that we become aware of and provide the necessary communication on our website as soon

as possible.

Terminal block

Please refer to the following table on Pin description relating to the terminal block:

Note: When powering the modem via the terminal block, the power cable should be wired with the correct voltage

polarity. Wrong wiring may damage the modem. Pin 1 and Pin 2 are reserved for power, where Pin 2 is “GND” and

PIN 1 is power input “Vin” (DC5~40V).

Note: The General Purpose I/O can be used as either Inputs or Outputs for SMS, Email or SNMP. When used as Digital

Inputs they are voltage Free connections. Digital Outputs are a 0-3.3VDC Output and are not suitable for driving

Relays.

For wiring instructions for the General Purpose, I/O please see Installation Guide for further details.
