Function
The 23-45x, Fiber Optic Transfer Trip Link is intended to extend binary functions over medium and long distances. E.g. transfer trip.
The link can be delivered with fiber optic components for distances up to 80km. The protocol used by the link is designed to have high security.
The transfer trip time is around 8ms from Binary Input to Binary Output.
The link is designed for duplex mode, (2 fibers). 4 signals can be transferred in each direction. The link can also be used in simplex mode (1 fiber). Note that the remote alarm function has no relevance in simplex mode.
Every binary input is “sampled” with 25Msamples per second.
The sampled input data is filtered for changes over a period of 1ms.
The filtered input data is sent as a data message on the fiber.
In order to increase the security, for example against disturbances, the protocol on the fiber, needs 4 consecutive equal data messages before any change of the Binary output.
In addition there is a fiber optic link-control, indicating correct received data messages. This is indicated to the user by a “Link OK” – LED.
There is also a “Local alarm” – LED, and a “Local alarm” relay. (Contact open at no error). The relay and the LED are activated when an error is found. For example, at link loss.
Both the “Local Alarm”-LED and -relay has a latched function. When an error is detected in the local unit, the Local Alarm-LED is lit and the Local Alarm-relay is activated. They stay activated until the Reset alarm button is pressed.
In duplex mode, the “Local alarm” – indication is sent to the remote unit, and there indicated as “Remote alarm”.
There is one “Remote alarm” – LED, and one “Remote alarm” relay.
The Remote Alarm-LED and relay has a monostable latch function. An error detected in the remote unit will be sent to the local unit and indicated by Remote Alarm-LED and relay. When the remote unit no longer detects errors, Link-OK, Remote Alarm-LED and the relay, are inactivated. Short remote error pulses are prolonged to some seconds of time, to make sure all Remote Alarms are detectable and visualized.
Both “Local alarm” and “Remote alarm” relay outputs have the same data as for the Binary outputs.
