FFI SYSTEM OPTICAL SIGNAL CONVERTER DATA SHEET The optical signal converter performs conversion between optical and electrical signals of FFI system specifications, and serves as an interface when connecting a detector or controlled element of an electronic instrumentation system to the FFI system. This is a high-precision intelligent instrument with a built-in microcomputer for digital processing of signals. Optical fiber is used in the signal transmission section which enables forming an optical fiber type field instrumentation system (FFI system) together with optical star coupler and master station. FRK FEATURES 1. Bidirectional transmission system Transmission of measured data and fault diagnosis data to the host computer and remote settings etc. from the host is done bidirectionally via a signal optical fiber cable. 2. Easy adjustment and setting operation Adjustment and settings can be made easily via remote operation from the host computer or by key switches on the indicating unit (option). 3. Self-diagnosis function A number of self-diagnoses are possible by the builtin microcomputer. 4. Digital display type field indicator available at option. 5. Flame-proof structure (d2G4) can be provided at option.

Power supply: 24V DC (20 to 30V) or 24, 100, 115, 220V AC ( ± 10%), 50/60Hz Power consumption: About 4W (DC power supply) or about 8VA (AC power supply) Setting: • Damping time constant up to 17 sec • Optical/electrical conversion output 0% and 100% calibration, readback 0% and 100% calibration • Electrical/optical conversion output 0% and 100% calibration Self-diagnosis: • Input overflow/underflow, microcomputer fault, battery down (for memory backup) • Optical/electrical D/A converter fault • External line disconnection fault Display (option): • Optical/electrical converter readback value (0 to 100%) • Electrical/optical conversion input value (0 to 100%) • Symbols and numerals for above setting items • Symbols for above diagnosis items … only at fault occurrence But microcomputer fault is not displayed since it is normalized through auto reset action. Ambient temperature: –20 to 60°C Ambient humidity: 95% R.H. or less Transmission: Half-duplex bidirectional transmission with one-fiber system Transmission distance; 1.2 km max. EDS9-44e Date Dec. 30, 1987 FRK Other: Optical output alone can be provided by combining the electrical/optical converter with an optical receiving converter (type PRN). In this case the transmission distance is 4 km max. Structure and Material Finish: Epoxy/polyurethane double coating, silver (cover; blue) Enclosure: JIS C 0920 immersion-proof (equivalent to IEC IP65 or NEMA 4) Outer dimensions (H x W x D) and Mass (weight): 161 x 172 x 212 (240) mm, about 4.0 kg Parenthesized dimension is when display unit equipped. Mounting method: Mounted by U bolt on horizontal or vertical 50A (2B) pipe, or wall mounted Cable and connection method: JIS G1/2 internal thread (Terminals: M4 screw) Optical fiber cable is Fuji-specified one (prepare separately) Connection is made by optical connector. Performance Specifications Accuracy rating: ± 0.2% Repeatability: ± 0.1% Ripple content: 1% P–P (optical electrical converter output current) Insulation: (in arrester exclusion status) Between power supply and signals Insulation resistance; 500MΩ or more (with 500V DC megger) Withstand voltage; 1000V AC for 1 minute Between power supply and ground Insulation resistance; 500MΩ or more (with 500V DC megger) Withstand voltage; 1000V AC for 1 minute Between signals and ground Insulation resistance; 500MΩ or more (with 500V DC megger) Withstand voltage; 500V AC for 1 minute Optical Specifications Indication unit: 6-digit LCD unit with setting key (4 pushbutton switches) Acid and alkali-proof treatment: Mounting U bolt and nuts material: SUS304 CODE SYMBOLS 12345678 9 10 11 FRK 1 2 3 1- Description Kind Optical/electrical conversion Electrical/optical conversion Electrical/optical conversion transmitter power supply built in Y A B C A B 1 2 3 4 5 0 2 1 3 4 Y B Input/output signals FFI optical signal/4 to 20mA DC (unusable with 2, 3 in 4th digit) 1 to 5V DC/ FFI optical signal (unusable with 1, 3 in 4th digit) 4 to 20mA DC/ FFI optical signal (unusable with 1 in 4th digit) 10 to 50mA DC/ FFI optical signal (unusable with 1, 3 in 4th digit) Indicating unit None Equipped Power supply 24V DC 24V AC, 50/60Hz 100V AC, 50/60Hz 115V AC, 50/60Hz 220V AC, 50/60Hz Arrester None Equipped Enclosure Immersion-proof case, non-explosion-proof Flame-proof case (conduit flame-proof screw coupling type) Flame-proof case (flame-proof packing type) Treatment None Acid/alkali-proof processing 2 OUTLINE DIAGRAM (Unit : mm) Indicating unit (optional specification) 172 119 53 Optical connection ø105 60 108 (28) 212 109 Conduit cnnection (See "Details of A") ø45 Indicating unit (optional specification) Pipe mouting 73 129 Details of A ø15 161 152 173 G1/2 (JIS) Mounting pipe JIS50A (2B) M8 U bolt Wall mouting 100 47 152 70 16 5 3 FRK OPERATING PRINCIPLE DIAGRAM Optical/electrical converter Indicating unit (option) Display Setting Optical connector Optical unit µ-Com Output circuit Readback circuit DC 4 to 20mA Electrical/optical converter Display unit (option) Display Setting Optical connector Optical unit µ-Com Input circuit DC 1 to 5V 4 to 20mA 10 to 50mA SYSTEM BLOCK DIAGRAM Signal converter FRK Electrical signal Optical fiber, 8 lines max.
