Working Principle PLC CPU sends output state command through rack backplane bus to TSXCDY120 module. The module’s onboard logic circuit receives command and drives corresponding output transistor to turn on or off. DC24V power supplies field loads through transistor channels. Current sampling circuit monitors output current of each channel continuously. When overcurrent or short circuit occurs on one channel, hardware protection shuts down that channel and sends fault signal to PLC CPU. LED indicator changes state according to channel output status.
Installation Requirements Insert module into matching TSX PLC rack slot and fasten locking clip; Field wiring uses stranded copper wire and tighten terminal screws to specified torque; DC24V field power supply must adopt regulated power source; Route signal wiring away from high voltage power cables; Connect rack cabinet protective earth.
Precautions for Use Verify field load current does not exceed single channel rating; Disconnect field power before wiring modification; Confirm hot swap support before removing module while rack powered; Check terminal screw tightness periodically; Do not install in environment with corrosive gas or excessive dust.
