Mencom Introduces Industrial Wireless Access Point to Protect Sensitive Data on the Manufacturing Floors
Posted on February 14th, 2018
The manufacturing industries and the utilities have been getting more automated, delocalized and more complex since the introduction of modern information technologies. The advanced smart grid system as an automated and distributed energy delivery network exemplifies how the complex network infrastructure works through connecting individual smart applications to operate traditional and modern renewable power plants together.
Since the cost of leased lines is lofty and some locations are not even accessible by traditional methods such as wired broadband or fiber backbone, dedicated and private communication lines to every device are no longer viable options to build such a large network. Therefore, these large network connections should be established either through the public Internet where broadband internet access is available or through the cellular wireless network so that end-users can easily access and control devices at a minimum cost.
These networks, however, are prone to encounter possible security issues during the data transfer. If sensitive data that was conventionally relayed over the private network is transferred over a public network without encryption, the system becomes vulnerable to various threats and can be compromised by malicious activities such as network penetration, unauthorized control, interception, and eavesdropping.
In order to secure the sensitive data, Mencom offers Industrial Wireless Access Points providing a reliable, robust, rugged, and cost-effective solutions to industrial applications that require a wireless connectivity. They are suitable for a wide array of applications and withstand harsh conditions typically found in the harsh manufacturing environment. In addition, a state of the art encryption and the ability to create a virtual network among wireless clients are integrated so that communications between clients can be easily and intuitively controlled while imposing restrictions on data and excluding malware can be done at the same time. Equipped with a powerful 2 x2 MIMO Radio interface supporting IEEE 802.11 a/b/g/n, 2.4 GHz and 5 GHz selectable bands, built-in DIN-Rail mount, these Wireless Access Points run in multiple modes such as – access point(AP) mode, wireless distribution bridge (WDS) mode or access point client operation mode.
Mencom Wireless Access Point embodies a strong wireless network manager to ensure the delivery of optimum performance in the network. WPS and Wi-Fi Direct technology options are also available to connect Wi-Fi easier and deliver an industry-wide peer-to-peer solution based on broadly deployed Wi-Fi technologies. These devices are designed to be fully operational between -20 and +60 °C.
Mencom now offers unique Inside-Outlet GFCI Power Port for Panel Interface Connectors
Posted on January 10th, 2018
Mencom’s unique Inside-Outlet (GFDP1) Power Port features three GFCI-protected receptacles; two outside and one inside the panel to provide a simple solution to comply with NFPA 79, The Control Panel Utility Receptacle Standard. In order to comply with the standard,
1. All utility receptacles must be GFCI Protected.
2. All External Utility Receptacles must be covered.
3. All covers must maintain enclosure rating.
4. OSHA (Occupational Safety and Health Administration) requires the inspection of all GFCI outlets every month to check if the NFPA 79 standard requirements are satisfied.
Since the non-GFCI outlets inside a panel can be wired through the GFDP1 that is externally installed on the panel door, it provides the ability to conveniently test the outlets without opening the cabinet door while satisfying the NFPA 79 standards. The inspector can simply walk to the panel door, fips the protective cover, and push the test button. This easy step not only helps prevent potential safety hazards (such as Arc Flash) associated with opening an electrical panel but also eliminates the need for costly personal protective equipment (PPE) and a licensed electrician to access the inside of the cabinet.
– 3 GFCI-protected receptacles (2 Outside & 1 Inside)
– 120V GFCI Receptacle to 120V Simplex Receptacle
– Easy and Safe TEST/RESET outside the panel
– Outgoing Terminals for GFCI Protected Power
– Finger-safe cover for internal connections to power ports
– UL Type 4, 4X, 12
– IP65 with Mencom metal/low profile housings
Mencom, as the industry leading manufacturer of Panel Interface Connectors, currently has well over 3,000 designs in production. Remarkably, however, their experienced engineer team is still creating new designs almost daily to meet the various market demands.

Industry-Specific Ethernet Switches for Power/Railway Networking
Posted on December 5th, 2017
The IEC 61850 for utility automation is the international standard to regulate a unified and standardized communication protocol for electrical substation and power grid automation. The new IEC 61850 standard focuses its domain knowledge on the electrical power grid system. It is an object-oriented protocol which utilizes a data modeling scheme that clearly describes each component (such as process objects, protection, and control functionality) of the grid or the substation as standard logical nodes. This enables data access to the power grid system to yield more details. IEC 61850 Part 3 also defines requirements for network and hardware that are suitable for substation automation. These requirements include electromagnetic immunity (EMI), surge protection, vibration, shock resistance, and temperature ranges that the devices in smart grid system should comply with.
