Overview Manuals Link Routing Power & Status Label Identity Installation Check

Features:

  • Transfers an electrical I/O Link through two labelled fibre-optic channels.
  • Provides separate Power, FO1, FO2, and I/O Link status indicators for path checks.
  • Uses an HN01 hardware identity with FIBRE750V1R0 software and revision F.
MTL 8937-HN forms the conversion point between the control-system I/O Link and the FO1/FO2 fibre paths.

Its supply and link indicators divide troubleshooting between incoming power, the electrical I/O connection, and the two optical channels.

The complete label identity should be matched because HN01, FIBRE750V1R0, and revision F describe the exact photographed configuration.

The MTL 8937-HN Fibre Optic Extender may still be available through Apter Power after OEM discontinuation.

Electrical-to-optical signal path

  • I/O Link side: The electrical control-system link enters through the labelled I/O Link connection.
  • FO1 channel: FO1 carries one separately indicated optical path.
  • FO2 channel: FO2 carries the second separately indicated optical path.
  • Channel records: Cable labels should preserve the FO1 and FO2 assignments at both ends.

Supply and diagnostic references

  • Voltage window: The nameplate specifies a 20–30 V DC supply.
  • Current marking: Maximum current is marked 85–74 mA across the stated voltage range.
  • Power indication: The Power indicator separates a supply problem from a link problem.
  • Path indication: FO1, FO2, and I/O Link indicators identify the part of the route to inspect.

Exact configuration markings

  • Version: HN01 identifies the photographed hardware version.
  • Software: FIBRE750V1R0 is printed on the exact unit.
  • Revision: The label records revision F.
  • Manufacturer: Measurement Technology Limited, Luton, England appears on the nameplate.

Checks before reconnecting the extender

  • Model match: Confirm the complete 8937-HN catalog number.
  • Configuration match: Compare HN01, FIBRE750V1R0, and revision F.
  • Fibre assignment: Keep FO1 and FO2 connected to their documented routes.
  • Ambient boundary: Maintain the surrounding temperature between −20 and +70 °C.
Description
MTL 8937-HN is a fibre optic extender for an electrical I/O Link, carrying control-system communication between separated locations through two optical paths. FO1 and FO2 provide individually identified fibre channels around the common electrical interface.

Power for 8937-HN enters through the 20–30 V DC input. Dedicated Power, I/O Link, FO1, and FO2 indicators separate a supply problem from an electrical-link interruption or an individual fibre-channel fault.

The two fibre paths of 8937-HN must retain the same FO1 and FO2 assignments at both ends of the route. The extender operates from −20 to +70 °C and draws no more than 85 mA at 20 V DC or 74 mA at 30 V DC.

Technical notes
MTL 8937-HN carries the exact HN01, FIBRE750V1R0, and revision-F identity; all three markings should be recorded before installation.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Which indicators should be checked first when MTL 8937-HN loses communication?
Start with the Power and I/O Link indicators on MTL 8937-HN, then compare FO1 and FO2 to isolate the interruption to the electrical side or one optical channel.
What supply must be present before testing MTL 8937-HN?
The supply input of MTL 8937-HN must remain within 20–30 V DC; the nameplate lists a maximum current of 85–74 mA across that range.
How can the two fibre paths on MTL 8937-HN be distinguished?
FO1 and FO2 are separately labelled on MTL 8937-HN and have individual indicators, so each installed cable should retain the same channel assignment at both ends.
Which label details identify the exact MTL 8937-HN configuration?
MTL 8937-HN is identified by HN01, FIBRE750V1R0, and revision F in addition to the complete 8937-HN model number.
Can MTL 8937-HN be installed above its stated ambient limit?
No. MTL 8937-HN is marked for an ambient range of −20 to +70 °C, so the enclosure temperature must remain inside those limits.
Why should both ends of an MTL 8937-HN fibre route be documented?
Recording the FO1/FO2 assignments and I/O Link endpoints for MTL 8937-HN prevents the two optical channels from being crossed during reconnection.
