Product Details
Apart from the binary I/P's, the 216DB61 unit is equipped with 8 tripping O/P's. Outputs 1...8 are available for use on the 216GD61a and, when there is a second 216GD61a, outputs 9...16 as well.
Binary I/P and tripping unit 216DB61：
The binary I/P and tripping unit comprises 16 I/P and 8 O/P channels. The O/P channels are used to transfer the tripping commands of activated protection functions to the 216GA62 tripping relay module. The I/P channels are used for external signals from the 216GE61 I/P relay module, which it transfers to the 216VC62a processing unit via the bus.
*connector "a" (upper) : I/P channels CHI01...CHI16
*connector "b" (lower) : channels CHO01...CHO08.
If there are several 216DB61 units in a system, the I/P and O/P channels are designated within the system.
The position of the plug-in jumper BR1 on the PCB of 216DB61 determines whether the "ENABLE" and "BLOCK CH OUT" functions are operational or not, i.e. whether the tripping channels CHO01...CHO08 are enabled or disabled. The enabling and blocking functions only concern the 216DB61 unit.
BR1 in position X4: (B/E inactive)
The ENABLE 1/2 and BLOCK 1/2 functions are disabled. I/P channels CHI13...CHI16 function as normal external I/P's, i.e. the signals are transferred via the bus to the 216VC62a unit as in the case of channels CHI01...12.
BR1 in position X3: (B/E active) The ENABLE 1/2 and BLOCK 1/2 functions are enabled.
The ENABLE 1 and 2 I/P's (CHI13 and CHI14) both have to be enabled (AND gate) for O/P channels CHO01...08 to be enabled.
In order to disable channels CHO01...08, a logical "1" must be applied to either the BLOCK 1 I/P or the BLOCK 2 I/P (CHI15 or CHI16; OR gate).
The tripping channels are also disabled, should a short-circuit occur in one of the tripping channel driving stages. Either channel group CHO01, 03, 05, 07 is disabled or channel group CHO02, 04, 06, 08, depending on in which group the short-circuit is.
