Internal Architecture and Energy Storage
The Schneider DO1130 Digital Output Module stores minimal energy in its output filters. Small ceramic capacitors hold approximately 180 microfarads total capacitance. Each output channel uses a power MOSFET transistor for switching. Thirty-two optocouplers isolate the logic backplane from field outputs. When the CPU turns on a channel, the optocoupler activates. The transistor then switches the output to 24 VDC potential. Each channel includes an electronic fuse for short circuit protection. Thirty-two green LEDs light up when their respective output turns on. A built-in temperature sensor shuts down all outputs during overheating.
Connection Interfaces and Wiring Details
You will find a 40-pin removable connector on the bottom face. This connector accepts 32 output wires plus common returns. Connect the external 24 VDC supply positive to the common terminal. Then, connect each load return wire to the output terminal. Use 18 to 22 AWG copper wire for all field connections. The Schneider DO1130 Digital Output Module requires an external 24 VDC power supply. Do not exceed 0.5 amps per channel or 4 amps total. Thirty-two green LEDs provide quick visual feedback for troubleshooting. A green PWR LED indicates proper backplane power. The module draws 250 mA from the +5 VDC backplane supply.
Configuration and Installation Steps
You slide this module into any I/O slot of the M340 rack. First, align the module with the upper and lower card guides. Then, push it firmly until the backplane connector seats completely. Secure the front panel with the integrated locking screw. Connect all field wiring before applying power to the system. The Schneider DO1130 Digital Output Module requires no jumpers or dip switch settings. Use the EcoStruxure Machine Expert software to control each output point. Map each output channel to a specific %Q memory address. The module automatically configures itself after power-up. Test each output with a multimeter before connecting loads.
