Industrial Ethernet Networks The industrial automation and process control industry utilizes specialized communications and networking equipment designed to operate reliably in extremely difficult environments. These include: Wide variations in operating temperature. High humidity. High levels of vibration and mechanical shock. Voltage transient conditions. EMI/RFI Exposure to airborne and particulate matter. Contact Closure Contact closure circuits still form a fundamental building block in some of the most safety-critical systems and networks globally. ComNet provides a range of optical interfaces to support the transmission from 1 up to 24 contact closure signals over a single optical fiber. SOLUTIONS FOR VERTICALS Security & Surveillance All IP based security and surveillance networks demand transmission equipment that will perform reliably over the lifetime of the installation and with the lowest possible life- cycle costs to the owner of the system. ComNet designs, builds, and tests this equipment to exceed the industry- accepted standards and provide innovative features that enhance the operability and performance of the system. For hardened network equipment, cybersecurity features that protect the integrity of the network in unconditioned and potentially unsecured environments are essential. Along with that, the ability to provide high PoE levels over the full operating temperature range of the equipment is a must for operators and integrators. ComNet has spent many years furnishing the security and surveillance market with transmission equipment that is fit for purpose. This long relationship puts ComNet in a position to understand the needs of the various edge equipment and to provide transmission solutions that complement the operational requirements of those multiple devices.
