Description
The external expansion module Zvezda Tekhnologiy with discrete inputs and outputs is designed for use in information collection systems, protection and automation of energy systems, and protection and automation schemes for public utilities.
The module is manufactured in a light-grey impact-resistant plastic case, made of impact-resistant heat-resistant ABS plastic UL-94V0, and provides for mounting on a 35mm DIN rail. The module plastic is resistant to UV radiation, temperature changes from -45 to +70°C. The modules are designed and manufactured with an increased safety margin for each of their parts.
The module is connected via quick-release connectors with screw clamps, which allows for quick installation and convenient operation of the device.
When properly installed, the module starts working immediately when power is supplied. After powering on, the module needs to be configured (speed, protocol, etc.).
