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.
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 utilise high quality industrial grade components enabling them to work in extended wide temperature environments. They are capable of running below -20C and above +70C and offer further protection than standard wide temperature rated products.
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.

MAQ20-DIV20 overview

  • 20 Discrete Input Channels
  • Interface to 10V to 32V DC Signals
  • +24V DC Compliance Voltage for Interface to Relay Contacts, Solid State Switches & Others
  • 1500Vrms Input-to-Bus Isolation
  • Each Channel Protected up to 150Vrms
  • Continuous Overload
  • User Defined Logic Polarity
  • Fast Switching Times
  • Field Input Connections Use Spring Cage
  • Terminal Blocks
  • Low Cost per Channel
  • -40°C to +85°C operating temperature
The MAQ20-DIV20/-DIVC20 modules have 20 discrete input channels that interface to 10V to 32V DC signals. The MAQ20-DIVC20 model has a +24V DC compliance voltage source on each channel for interfacing to relay contacts, solid state switches, or other devices that require an excitation. Discrete input states can be read individually or as a block. Logic polarity can be user defined as standard or inverted.

The field inputs are designed for harsh industrial environments and have fast switching times. Pulses as narrow as 200μs can be measured. Field input connections are made through high density spring cage terminal blocks.

Input-to-bus isolation is a robust 1500Vrms and each individual channel is protected up to 150Vrms continuous overload in case of inadvertent wiring errors. The high channel count within the narrow module package gives exceptional functionality while preserving valuable mounting space. The high density minimizes cost per channel resulting in economical monitoring solutions.

All MAQ20 modules are designed for installation in Class I, Division 2 hazardous locations and have a high level of immunity to environmental noise commonly present in heavy industrial environments.
