9.Using Optional Modules - 9.4.16 Channel Logic Module (RA30-105)
1WMPD4004444 111
(6) Input signal: Select voltage or contact. This setting can be selected for both CHA (8 ch) and CHB
(8 ch).
(7) Threshold setting: When Input signal is set to voltage, V-Threshold (7) can be set.
Three types of threshold for voltage detection can be selected.
When Input signal is set to contact, V-Threshold (7) can be set.
Three types of threshold for contact detection can be selected.
(8) Disp. pos.: Sets the display position for the logic signal of CHA or CHB.
The L level position of CH-4 is the set value.
(9) Disp. range: Sets the display amplitude for the logic signal of CHA or CHB.
Specified as the percentage of the display width when the full range of the monitor is
100%.
The eight channel signals are displayed at equal intervals and the overall display
width can be set.
(10) Display signal: Selects the channels to display. This can be selected for each of the eight channels in
CHA and CHB.
(11) Sheet: Displays the sheet number when using monitor display or printer recording for CHA or
CHB. You can tap SHEET to change the sheet number.
9.4.3. Measurement Setup
CAUTION
The maximum voltage input is 24 V.
Take care, as applying high voltage can damage the module.
Use the 1539S floating voltage probe when inputting high voltage.
Check the slot number and channel, connect the signal to the corresponding input module, and enable
Meas. to display the input waveform on the monitor screen. Perform adjustment for the required
signal waveform while viewing the waveform.
Follow the procedure below to set the input CHA and input CHB.
Step 1. Select voltage or contact in Input signal (6).
For voltage input, the high/low state of the voltage is displayed as two value data with the
waveform indicating the H/L level.
For contact connection, the open/closed state of the non-voltage contact is displayed as two value
data with the waveform indicating the H/L level.
