Figure - Schematic diagram of CT use (in the left figure, CT2s output 2 is an IO expansion
module; in the right figure, CT2s output 2 is an expansion ca ssette)
D. Designated CT channels: (communication addresses are shown in the table below)
Depending on the DTM host or measurement expansion module to be assigned, in
accordance with the internal station number (y: 1~F) and channel (z: 0~7), write the content of
H00yz to the corresponding communication address
Example: When CT1 is desired to assign the DTM-CT030 [channels 1] of internal station number 4 to the
measurement expansion module [output 1 of input channel 1] of internal station number 2, write the content of
[H0040] to address [H21C0].

E. CT sensor mode:
By default, each channel of the DTM-CT030 is used in conjunction with a 30A CT sensor. If a
100A CT sensor must be used, the content must be written to the corresponding communication
address.
(Communication addresses and their content are as shown in the table below; channels
correspond to bit numbers Bit0~7→CH1~8, 0 = 30A; 1 = 100A)
Example: If CH1, CH3, CH5 of DTM-CT030 with internal station number 6 must be used with a 100A CT, the
content of [H0015] must be written to address [H6841].
