STR 100 - Signal Transducer

2 STR 100 SYSTEM

2.1 DESCRIPTION

STR 100 is modular system of communication devices that can be used for various of tasks such as:
distance protection criteria transfer
disconnector and circuit breaker statuses transfer between substations
signal transfer via communication through noisy industrial enviroment
status and command transfer for remote switch

2.2 FEATURES

Wide range power supply
Digital input voltage suitable for substation's power supply
RS232, RS485, Fiber Optic or Ethernet communication interface
Switch selected BAUD rate
4 digital inputs
4 dIgital outputs
DIN 35 rail mount
Short response time

2.3 FUNCTION

Two devices from STR 100 system works in pair. Input statuses from one device are transfered to second device outputs and vice versa. Devices are coupled through full duplex commnication link. Communication is based on special protocol. If communication link is broken DO statuses of both devices are returned to theirs inital states. Speed of communication can be selected by switches. One of DOs has two functions. It can operate as normal DO or as communication failed signalization. Selection between functions is made by switch.

FUNCTION
All normaly used connectors, switches and light indicators are accessed at the front side of the device. One light indicator indicates power supply voltage, others indicate communication and IOs activity.

2.4 TYPICAL APPLICATION

Typical application is transfer of trip command and circuit breaker status between two substations.

STR 100 - Signal Transducer
All devices from STR 100 system are based on various boards. There are three groups of boards. One main board, one or two communication boards and one IO board is used in one device :
main board with power supply
HI – high voltage power supply board
MD – medium voltage power supply board
LO – low voltage power supply board
communication interface
RS232 board
RS485 board
Versatile (650 nm) 1 mm plastic fiber optic board (~110 m)
Multimode (820 nm) fiber optic board (~2000 m)
Singlemode (1310 nm) fiber optic board (~20 km)
Ethernet board
IO board
IOL – 4 Digital Input (24 V DC), 4 Digital Output board
IO4 – 4 Digital Input (48 V DC), 4 Digital Output board
IO1 – 4 Digital Input (110 V DC), 4 Digital Output board
IO2 – 4 Digital Input (220 V DC), 4 Digital Output board
User can order any combination that suits him or her best.

2.6 HOUSING

Housing of STR 100 system devices is aluminium and intended for mount on standard DIN 35 rail (acc. to DIN EN 50022-35). Housing is same for all combinations.

2.7 INTENDED USE

Device are intended for use in cubicles and cabinets in all kinds of power production, transmission and distribution stations as well as in industry. It requires no maintenace.

4 HARDWARE DESCRIPTION

Hardware is based on main board (power supply), interface board and IO board (DIs and DOs).

4.1 MAIN BOARD

Main board provides neccesary power to other parts of the device and place for interface board. On the board there are also three LEDs. The yellow LED shows activity on receive (Rx) line and the green one shows activity on transmit (Tx) line. Additional green LED indicates the device power supply activity. User can choose between two main boards:
HI – high voltage power supply board
MD – medium voltage power supply board
LO – low voltage power supply board

For further technical data see chapter „TECHNICAL DATA“.

4.2 INTERFACE BOARDS

User can choose between following interface boards:
RS232 board
RS485 board
Versatile link plastic fiber optic board
Multimode Fiber Optic (ST connector) board
Singlemode Fiber Optic (SC connector) board
Singlemode Fiber Optic (FC connector) board
Singlemode Fiber Optic (ST connector) board
Ethernet board
Although STR 100 device can have two interfaces it can communicate only with one at the time. Data is always received and transmited to both interfaces (ports).

4.2.1 RS232 INTERFACE BOARD

Description
Single, nonisolated, full duplex, RS232 port with DB9 female connector. Supported Rx, Tx and GND pins.

4.2.2 RS485 INTERFACE BOARD

Description
Single, galvanically isolated, half duplex, RS485 port with Phoenix 3 pin screw connector, with automatic switch to receive after end of transmission and with additional terminating and stabilizating resistors.
Hardware settings
For proper functioning of that board some settings must be done:
RS485 bus termination and stabilisation
baud rate
RS485 bus termination and stabilisation
TERMINATION At high transmission rates or long distance, RS485 bus termination is necessary.
The termination on RS485 bus must be set on both ends of the RS485 bus.
STABILISATION Some device, to work properly, demands that RS485 must always be in known and valid state. That is, when + (positive) pin is more than 200 mV positive than – (negative) pin. Pins + and – are sometimes marked as A and B. In case that no device on RS485 bus is transmitting or in case of short circuit, there is no voltage difference between those pins and some device do not work correctly. On this port board so called „true fail-safe“ RS485 chip is used so board works correctly without stabilisation at invalid RS485 bus state. But still switches for stabilisation are provided on port board.
The stabilization on RS485 bus may be set on one device only!
Switches at the lower side of connector:
Switch 4 5 6

BAUD rate setting 19k2 (bps) is valid for all standard communication protocols, that do not request special timings. If special protocols (small request-respond time required) are used please note it in order.
NOTE! If there are problems with communication, try using higher speed setting. Some manufacturer have different markings for B and A line. Try to switch A and B wires. See
http://en.wikipedia.org/wiki/RS-485 for detailed information.
