Wiring procedure
• For the cable type to use, see “
n
Types of Wiring and Cabling”.
• Be sure to ground the cable shield on the TDLS8000 side and on the other side.
• The open and closed levels of the digital inputs are identified by the resistance seen from
the TDLS8000 side. Wire the digital inputs to meet the following conditions. Note that wiring
resistance is included.
If the DI terminals are shorted, about 2 mA of current will flow.
Closed Open
Resistance 200Ω or less 100 kΩ or more
3.2.7 Wiring Solenoid Valve Control Outputs
These outputs control the solenoid valves that are used during calibration and the like. There are
