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.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
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.
