Relay Compositions of DTV Relay Stations

(Product code: 6555A)

Outline

This is controller for the relay station transmission system of Digital Terrestrial Broadcasting. The state of each equipment of one method is observed, and when abnormally generated, this controls it automatically. Moreover, the remote control watch is possible according to the remote control device separately prepared. When becoming a power line failure, the power supply control of PA is released.

It is possible to mount on 50mm in height and space-saving.

Internal setting
Compulsion start control method 1/2	Whether the compulsion start of the control input is started, stopped by one point of contact or it starts and it stops respectively by two points of contact can be set. 1 point of contact for ON, 2 points of contact for OFF. (initial state OFF)
Reset at start of the broadcasting	Whether reset and the compulsion star of both methods are done or not can be set. (initial state OFF)
Abnormal detection time	Time to detect abnormality can be set.1 to 16[s]: settable in 1[s] step. (initial state: 1[s])
Broadcasting stop time	After the broadcasting stop item is detected, time to control PA stopping can be set. 0 to 5[s]: settable in 1[s] step 10 to 30[s]: settable in 5[s] step 40 to 80[s]: settable in 10[s] step (initial state: 60[s])

Function

This equipment observes the state of each equipment, and When detects abnormality, outputs the observing status of the abnormal equipment, and puts on the corresponding LED.
At abnormal recovery, this stop the corresponding output, and keeps the state of lighting of each LED without to the corresponding LED and SW alert LED. It doesn't turn LED off in an abnormal recovery.
LED that maintains lighting is turned off by display reset SW.
