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.
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.
CSA certification indicates that a product, process or service has been tested to a Canadian or U.S. standard and it meets the requirements of an applicable CSA standard or another recognised document used as a basis for certification.
FM approved certification is a standard set by FM Global. Industrial and commercial companies around the world rely on products and services that are FM approved and specification tested to protect their properties from loss. The FM APPROVED mark, which is backed by scientific research and testing, advises customers that the product conforms to the highest standards.
ATEX is the name commonly given to the European Directive 94/9/EC, also known as ATEX 95 or ATEX Equipment Directive. The regulation applies to all equipment intended for use in explosive atmospheres, whether electrical or mechanical, including protective systems. There are two categories of equipment 'I' for mining and 'II' for surface industries. The directive covers a large range of equipment, potentially including electrical equipment used on fixed offshore platforms, in petrochemical plants, mines, flour mills and other areas where a potentially explosive atmosphere may be present.

  • 100Hz Signal Bandwidth
  • Provides an Isolated +24VDC Supply to Power the Loop
  • Provides High Level Voltage Outputs
  • 1500Vrms Transformer Isolation
  • Accuracy, ±0.03% of Span Typical, ±0.1% Max
  • ANSI/IEEE C37.90.1-1989 Transient Protection
  • 120Vrms Input Protection
  • CMRR, 105dB

SCM7B35 current input modules accept input signals in the 4-20mA range from the field and provide a high level voltage output to the process control system. Current to voltage conversion occurs internal to the module, which is factory calibrated to ensure the highest accuracy.

Loop power is provided by the module, enabling a 2-wire transmitter to be directly connected without the need for a separate dc power supply for the 2-wire transmitter.
