3.2 Input and Output Signals
3.2.1 Input Signals
AC input signals
Table 3.2.1 shows the AC input signals necessary for each of the GRT100 models and their
respective input terminal numbers. See Appendix G for external connections.
Winding 1, 2 and 3 in the Table correspond to high-voltage or primary, medium-voltage or
secondary, and low-voltage or tertiary winding respectively.

Binary input signals
Table 3.2.2 shows the binary input signals necessary for the GRT100, their driving contact
conditions and functions enabled. See Appendix G for external connections.
The binary input circuit of the GRT100 is provided with a logic level inversion function as shown
in Figure 3.2.1. Each input circuit has a binary switch BISW which can be used to select either
normal or inverted operation. This allows the inputs to be driven either by normally open or
normally closed contacts. Where the driving contact meets the contact conditions indicated in
Table 3.2.2 then the BISW can be set to “N” (normal). If not, then “I” (inverted) should be
selected.
The default setting of the BISW is "N" (normal) for all input signals.
Further, all binary input functions are programmable by PLC (Programmable Logic Circuit)
function.
If a signal is not required, the function concerned is disabled.
The operating voltage of binary input signal is typical 74V DC at 110V/125V DC rating and
138V DC at 220/250V DC. The minimum operating voltage is 70V DC at 110/125V DC rating
and 125V DC at 220/250V DC.
