CE is a mandatory standard for products on the market in the European Economic Area. By CE marking a product, the manufacturer ensures that the item meets the essential safety requirements set out in the applicable CE directive.
This product fully adheres to the Restriction of Hazardous Substances Directive 2002/95/EC, RoHS for short.  The directive covers the restriction of use of certain hazardous substances in electrical and electronic equipment and was adopted in February 2003 by the European Union.
Underwriters Laboratories (UL) is an independent product safety certification organisation based in the United States. UL develops standards for products, materials, components, assemblies, tool and equipment, mainly dealing with product safety.
The National Electrical Code (NEC) defines hazardous environments as areas “where fire or explosion hazards may exist due to flammable gases, vapours, liquids, dust or particles”. When such materials are found in the atmosphere of an area, a potential for explosion exists, which could be ignited if an electrical or other source of ignition is present. As defined by the classification authorities, certified devices are suitable for installation and operation within a Class 1, Division 2 environment. Class 1 environments are areas where there is a presence of flammable gases or vapours in the air, such as natural gas or petroleum vapour. Facilities including oil rigs, refineries, gas plants and automotive repair centres all fall within this category.
These devices and systems have been designed to accept a wide voltage DC power input. This feature is desirable in the industrial market where a fixed voltage level or mains AC power cannot be guaranteed.
The Federal Communications Commission (FCC) is an independent agency of the United States government that sets standards and governs the testing of conducted and radiated emissions such as EMI.
These products come with a standard five year manufacturer warranty.

EKI-1224 overview

  • 2x 10/100 Mbps Ethernet ports for LAN redundancy
  • 4x RS-232/422/485 software selectable serial port
  • Integration of Modbus TCP and Modbus RTU/ASCII networks
  • Supports baud rates up to 921.6 kbps
  • Supports up to 16 connections and 32 requests simultaneously
  • Supports 31 slaves per serial port
  • Auto searching slave ID over configuration utility
  • Built-in 15kV ESD protection for all serial signals
  • Class 1 Div 2 and ATEX Zone 2 approved for hazardous locations
EKI-1224 Modbus gateways are bi-directional gateways for integrating new and existing Modbus/RTU and Modbus/ASCII serial devices to newer TCP/IP networked-based devices. They have Class 1 Div 2 and ATEX Zone 2 approval for hazardous locations and are suitable for oil & gas and pretrochemical applications.

The EKI-1224 feature dual independent Ethernet ports and MAC addresses to provide a redundant networking mechanism to guarantee Ethernet networking reliability.

The EKI-1224 Modbus gateways provide a simple and cost-effective way to bring the advantage of remote management and data accessibility to thousand of devices that cannot connect to a network.

The EKI-1224 provides a feature that can allow users to select master or slave operation mode for each serial port. They not only allow an Ethernet master to control serial slaves, but also allow serial masters to control Ethernet slaves.
