Input Circuit
SI SI Connecting to
sequence input signals
• Connect to a contact of switch and relay, or a transistor
of an open collector output.
• Use a switch or relay for micro current so that insufficient
contact can be avoided.
• Lower limit of the power supply (12 to 24V) should not be
less than 11.4V in order to secure the appropriate level
of primary current of the photo coupler.

AI Analogue Command Input
• There are three analogue command inputs of SPR/RTQR
(14 pins), CCWTL (16 pins) and CWTL (18 pins).
• The maximum permissible input voltage is 10V. For the
input impedance of these inputs, see the right figure.
• If you make a simplified circuit comprising a variable re-
sistor (VR) and resistor (R), refer to the right figure.
When the variable range of each input is -10V to +10V,
the VR should be a B type resistor of 2k
The R should be 200
• The A/D converters for these inputs should have the fol-
lowing resolution.
