SERCOS SERCOS, the abbreviation of SErial Real-time Communication System, is a standard digital communication interface for industrial CNC applications. SERCOS is a European (EN 61491) and an international standard (IEC 61491). This optical interface allows data rates 2, 4, 8 and 16 MBd and data value conversion via fiber optic control and drive with voltage isolation and noise immunity. The HFBR- 1505A and HFBR-2505A products meet the SERCOS optical specification characteristics and connector styles, and guarantee performance up to 10 MBd. (Usually 16mbd is also available through SERCOS but please contact Agilent about 16mbd devices.)

Fieldbus

PROFIBUS is a process field bus, an open fieldbus standard defined for data from 9.6 kBd to 12 MBd (optional steps) wire and fiber. Fieldbus is the German National Standard and the European CENELEC Standard EN 50170. The ST® connector is the recommended optical port for the PROFIBUS fiber version but other connectors are allowed as well. The HFBR-1515B and HFBR-2515B are fully compliant with the Plastics Technical Guide for fibres up to 6mbd, as well as guaranteed performance data rates up to 10 MBd. (Normally 12 MBd is possible, but please contact Agilent about planned devices for 12 MBd) INTERBUS-S Inc. INTERBUS-S, a special open sensor/actuator bus found widely accepted by factories in the automation industry. Specifically designed for this application, the HFBR-1505C and HFBR-2505C work with 1 mm POF and 200 micron HCS fibers at specified data rates of 500 kBd and 2 MBd. The optical transmission guide is a draft of the national DIN E 19258 standard in a German supplement. At European level, prEN 50254 is the INTERBUS-S fieldbus.

Colored connector ports. This one is easily identified by the dark grey connector port. The receiver is a light grey transmitter easily identifiable flame retardant plastic. This VO (UL file #E121562) flame chemical resistance and UL 94 strength, heat resistant, packaged with premium materials for low cost, dual in-line transmitters and receivers The full HFBR-X5X5X series package is designed for automotive Dirt by design; enough methanol on a cotton swab to remove clean compressed air is often blocking the light path. Avoiding the use of cable ferrules requires clean port optics and good system performance to keep the optics clean. It is also effective to advise the enquiry operation and design when leaving the protective cover on for soldering.

The specified link performance is 0°C to +70°C unless otherwise specified.

notes:

1. Use the recommended Tx and Rx circuits (60mA rated drive current).

2. POF HFBR exxyy 0.23db/m worst case attention.

3. HCS® 10 dB/km worst case attenuation.

4. Include a 3db optical safety margin for calculating the service life of the link.

5. Includes a 2dB optical safety margin accounting for link service life.

6. Signaling rate DC to 10 MBd.

7. The signaling rate is 2 MBd.

HFBR-15X5X power supply can be used at the same time. High light output light grey non-conductive plastic in a HFBR-15X5X transmitter transmitter plastic optical fiber (POF) and with ST® connectors. Hard Clad Silica (HCS®). This circuit is compatible with SMA connectors when the HFBR-1515X is mated. The HFBR-1505X is a 10mbd transmitter with a simple driver that can operate up to

Peak output power is 0°C to +70°C unless otherwise specified

notes:

Typical data at 1.25°C.

2. Measure the optical power with a large area detector at the end of a 0.5 m diameter plastic optical fiber.

3. The minimum and maximum values of Pt over temperature are based on a fixed drive current. Recommended driver circuit temperature compensation reduces PT variation with temperature, see Figure 4 and Figure 6.

4. Thermal resistance is measured with a transmitter attached to the connector assembly and optical fiber and mounted on a printed circuit.

5. To further reduce thermal resistance, the cathode trace should be as large as possible for good RF circuit design.

6. For IF, PK>60mA, duty cycle must keep IF, AVG≤60mA, pulse width≤1µs.

7. 1.6 mm below the seat surface.

8. The 1505C series only has a minimum peak output power of -5.3 dBm (POF) and -16.0 dBm (HCS?) at 25 degrees Celsius.

9. Optical power detector measured at the 1-meter end of a 1 mm diameter plastic or 200 μm large-area hard-clad silica fiber.

10. Pins 1 and 4 are used for mounting and securing, but are electrically connected; pins 5 and 6 are electrically isolated. It is recommended to ground pins 1, 4, 5 and 6 all to reduce the coupling of electrical noise.

11. The output power of 200 μm hard-clad silica fiber has a typical -10.5 dB difference compared to 1 mm plastic fiber.

HFBR-2505C ReceiverVCC's resistors are in transistors. The pull-in open collector Schottky output coupled digital IC receiver includes pin 5 of the monolithic DCHFBR-2505C receiver. The receiver housing is dark grey conductive plastic and the optical port is compatible with SMA connectors. The fid signal rate of the specification HFBR-2505C is 2 megabytes.

notes:

1. 1.6 mm below the seat surface.

2. A 0.1µF bypass capacitor must be connected from pin 6 to pin 7 of the receiver. The total length of wire between the ends requires that pins 1 and 4 be grounded to maintain the effectiveness of the conductive housing shielding.

3. Pins 1 and 4 are electrically connected to the conductive housing and are also used for installation and fixation. It is the capacitor and the length of the pins should not exceed 20 mm.
