Note the following:
IMPORTANT
• The "-DC24" terminals on the Input (terminal 2) and Output (terminals
2 and 3) Terminal Blocks are internally shorted.
• "NU" means that the terminal is not used / no connection.
• Inputs I-00, I-01, I-02, and I-03 are shared between digital and analog
inputs.
• Inputs I-00, I-01, I-02, and I-03 can only be used in sinking input
configuration.
• I-00 to I-03 are non-isolated input channels, do not connect -DC24
(Input terminal 2) to Earth/Chassis ground.
• Do not connect -DC24 (Output terminal 2) to Earth/Chassis Ground
