ABB 3BHE025883R0101 Input logic module

The MTL5053 has been specifically developed to extend 31.25kbit/s (H1) fieldbus networks into hazardous areas. It provides power and communication to devices powered through the signal conductors. For installations in which the safe-area bus length is small an internal terminator can be enabled by a switch on top of the module. The MTL5053 complies with requirements of Fieldbus Foundation™ specified power supply Type 133† (IS power supply). SPECIFICATION See also common specification Location of fieldbus device(s) Zone 0, IIC, T4–6 hazardous area if suitably certified Hazardous-area fieldbus power supply 18.4V ± 2% 105Ω ±3% dc impedance 80mA maximum current

Maximum cable length

 Determined by IS requirements, depending on other devices attached and maximum acceptable voltage drop along cable Digital signal transmission Compatible with 31.25kbit/s fieldbus systems and complies with fieldbus standards† Supply voltage 20 to 35Vdc LED indicator Green: one provided for power indication Power requirement, Vs, with 80mA output load 135mA typical at 24V 105mA at 35V Power dissipation within unit, with 80mA output load 2.3W typical at 24V 2.6W maximum at 35V

To assist the process of terminating cable screens, screw terminals have been provided in terminals 3, 6, 7 and 10. Please note, however, that there is no internal connection for these terminals so they are not earthed.

Note:

 To allow adequate heat dissipation under all likely thermal conditions, it is recommended that MTL5053’s are installed on a horizontal DIN-rail mounted on a vertical surface* with a 10mm space between adjacent units. MTL MS010 10mm DIN-rail module spacers are available for this purpose. * If an MTL5053 is mounted in a non-optimum orientation, the maximum operating temperature is reduced to 45°C.

The applicable fieldbus specifications and standards are: Foundation fieldbus™ 31.25kbit/s Physical Layer Profile Specification, document FF-816, IEC 61158-2: 1993 and ISA-S50.02-1992 for 31.25kbit/s fieldbus systems
