Energy Storage and Data Retention

The Schneider DTA 113 stores energy using three different storage components. Two electrolytic capacitors filter the 24 VDC input for stable processor operation. A supercapacitor provides backup power for SRAM data retention. This supercapacitor retains program variables and retentive values for up to 30 days. Consequently, the controller preserves critical data without a replaceable battery.

Input and Output Configuration

You will find eight digital inputs accepting 24 VDC sink signals. Each input includes an optocoupler for isolation from field wiring. Six digital outputs use NPN open-collector transistors with short-circuit protection. The outputs can drive relays, solenoids, and indicator lamps directly. Thus, this PLC handles typical machine control tasks without additional modules.

Installation and Diagnostic LEDs

Status LEDs sit on the front panel for real-time diagnostics. A green Power LED indicates correct 24 VDC supply connection. A green Run LED flashes during program execution. Eight green LEDs show the status of each digital input. Six green LEDs display the on/off state of each output channel.
