Transducer Inputs/Outputs; Dcma Inputs - GE C70 Instruction Manual

CHAPTER 5: SETTINGS
UR IED 1
DIRECT OUT 2 = HYB POTT TX1
In three-terminal applications, both the remote terminals must grant permission to trip. Therefore, at each terminal, direct
inputs 5 and 6 are ANDed in FlexLogic and the resulting operand configured as the permission to trip (
setting).

The C70 is provided with optional DCmA capability. This feature is specified as an option at the time of
ordering. See the Order Codes section in chapter 2 for details.
Hardware and software are provided to receive signals from external transducers and to convert these signals into a
digital format for use as required. The relay accepts inputs in the range of –1 to +20 mA DC, suitable for use with most
common transducer output ranges; all inputs are assumed to be linear over the complete range. Hardware details are
contained in chapter 3.
