          PRODUCT DESCRIPTION

          6ES7123-1GB00-0AB0 Two-channel Current Input Submodule

          Siemens 6ES7123-1GB00-0AB0 is a SIMATIC SC two-channel analog current input submodule for the ET 200L-SC arrangement. It accepts either 4 to 20 mA or bipolar -20 to +20 mA signals and occupies one of the eight submodule positions on a TB 16SC terminal block. Each current input has a nominal resistance of 50 ohms.

          The submodule uses an integrating conversion method, with 13-bit resolution on the bipolar range and 12-bit resolution on the 4 to 20 mA range, including overrange. Its configurable integration and digital filtering adapt the response to the selected interference rejection and smoothing. A 24 V DC supply provides the electronics, with a maximum supply current of 30 mA and typical dissipation of 0.6 W.

          SYSTEM INTEGRATION

          Integrate 6ES7123-1GB00-0AB0 within SIMATIC ET 200L-SC

          Allocate one free TB 16SC position and configure the two current channels for their actual transmitter ranges. A 4 to 20 mA channel and a bipolar current channel use different coding ranges and resolutions, so the controller scaling must follow the selected channel parameters rather than a generic voltage-input conversion.
          Route the shielded signal cables within the documented 200 m limit and account for the 50-ohm input burden in each transmitter loop. The stated 40 mA value is a permanent destruction limit, not a normal operating range. Apply the terminal-block wiring and power arrangement specified for the installed ET 200L-SC station.
          Choose the integration setting for the local interference conditions and then select one of the four smoothing levels. Filtering spans 1, 8, 64 or 128 cycle times and can substantially change the response to a signal step. Validate the resulting conversion delay and scaled values before releasing the signals to the process logic.

          Features:

          • Analog input channels: 2
          • Rated supply: 24 V DC
          • SIMATIC ET 200L-SC
          Use 6ES7123-1GB00-0AB0 only within the documented SIMATIC ET 200L-SC arrangement and applicable installation instructions.
          INTERCHANGEABILITY

          Replace 6ES7123-1GB00-0AB0 within SIMATIC ET 200L-SC

          Record the terminal-block position, current range and smoothing settings for both channels before removing the submodule. The 6ES7123 current-input version must retain its specified TB 16SC connection arrangement; a visually similar voltage or output submodule has a different electrical function and must not inherit the same field wiring.
          Isolate the transmitter circuits and station supply using the installation procedure for the ET 200L-SC assembly. Identify each loop and its polarity, inspect the terminal contacts, and retain the shielding arrangement. Compare the replacement article number and current ranges with the removed unit before reconnecting either transmitter.
          Restore the channel parameters and confirm the raw and scaled readings at known current values. Check the response after a change of input, especially where smoothing was enabled. A satisfactory static value alone does not establish that the integration time and filtering match the controller program and process response requirements.
