          PRODUCT DESCRIPTION

          6ES7138-6BA00-0BA0 Counter and Position Decoder Module

          Siemens 6ES7138-6BA00-0BA0 is the TM PosInput 1 counter and position-decoder module for SIMATIC ET 200SP. It connects RS422 incremental encoders, 5 V TTL push-pull incremental encoders or SSI absolute encoders, and includes two 24 V digital inputs and two transistor outputs. The module fits a type A0 BaseUnit and operates from a 24 V DC supply within the specified 19.2 to 28.8 V range.

          Incremental signals are accepted at up to 1 MHz, with quadrature evaluation supporting a counting frequency of up to 4 MHz. SSI telegrams can contain 10 to 40 bits in binary or Gray coding, with a maximum clock of 2 MHz. Each digital output is rated 0.5 A, with 1 A permitted in total. Address allocation and engineering requirements depend on the selected operating mode and firmware, rather than being identical for every configuration.

          Information needed before ordering

          Three direct checks to secure your system integration and minimize ordering risks.

          Information

          System integration Replacement check Manuals & support
          SYSTEM INTEGRATION

          Integrate 6ES7138-6BA00-0BA0 within SIMATIC ET 200SP TM PosInput 1

          Install TM PosInput 1 on a compatible A0 BaseUnit and include its 75 mA maximum electronics consumption in the 24 V supply budget. Encoder power is separately limited to 300 mA. Apply the ET 200SP wiring and shielding instructions to the differential encoder lines rather than treating them as ordinary 24 V discrete inputs.
          Select the incremental or SSI interface and enter the actual encoder coding, telegram length and clock settings. Incremental input frequency is limited to 1 MHz; the 4 MHz figure describes quadrature counting. SSI permits 10 to 40 bits, but the chosen clock must also suit the encoder and installed cable.
          Match the engineering package to the installed firmware and operating mode. The Siemens table distinguishes Standard, Fast and Motion address allocations and lists different TIA Portal requirements for successive firmware versions. Validate the digital input functions and both 0.5 A output loads before enabling the position-dependent functions.

          Features:

          • Nominal supply: 24 V DC
          • Supply limits: 19.2 to 28.8 V DC
          • SIMATIC ET 200SP TM PosInput 1
          Use 6ES7138-6BA00-0BA0 only within the documented SIMATIC ET 200SP TM PosInput 1 arrangement and applicable installation instructions.
          INTERCHANGEABILITY

          Replace 6ES7138-6BA00-0BA0 within SIMATIC ET 200SP TM PosInput 1

          Record the complete 6ES7138-6BA00-0BA0 code, installed firmware, encoder type and configured operating mode. Preserve SSI clock, coding and bit length or incremental evaluation settings; a matching article number does not by itself recreate the station parameters.
          Make the affected motion safe under the machine procedure, isolate the required circuits and inspect the BaseUnit and encoder connections. Preserve differential-pair polarity, shielding and encoder-supply wiring. Check the combined digital output load against the 1 A module limit before reconnecting the spare.
          Restore the station configuration and compare the reported position or count with a known reference. Exercise the assigned digital inputs and outputs, and review channel diagnostics before resuming normal motion. A reversed encoder pair or incorrect SSI format must be resolved before the count is used by the control program.

          • 6ES7138-6BA00-0BA0 complete order code
          • Typical power loss: 1.9 W

          FREQUENTLY ASKED QUESTIONS

          Questions buyers ask about 6ES7138-6BA00-0BA0

          Direct answers about identity, compatibility, stock, warranty, payment and shipping.

          • Does 6ES7138-6BA00-0BA0 accept an SSI encoder instead of incremental pulses?

            Yes. 6ES7138-6BA00-0BA0 supports SSI telegrams of 10 to 40 bits with binary or Gray coding; select the correct configured encoder mode.

          • Why do encoder frequency and counting frequency differ on 6ES7138-6BA00-0BA0?

            For 6ES7138-6BA00-0BA0, 1 MHz is the incremental input limit and 4 MHz is the quadrature counting limit. Compare the encoder signal frequency with the input limit.

          • Can 6ES7138-6BA00-0BA0 power an encoder drawing 400 mA?

            No. The documented encoder supply capacity of 6ES7138-6BA00-0BA0 is 300 mA maximum; a 400 mA encoder exceeds that rating.

          • Which wiring base must remain with a replacement 6ES7138-6BA00-0BA0?

            6ES7138-6BA00-0BA0 requires a type A0 BaseUnit. Check the installed BaseUnit and terminal assignment before exchanging the electronic module.

          • How should two loaded outputs on 6ES7138-6BA00-0BA0 be checked?

            Each output of 6ES7138-6BA00-0BA0 is rated 0.5 A and their total is limited to 1 A. Verify both individual loads and their combined demand.

          • What signal standard should maintenance identify before connecting 6ES7138-6BA00-0BA0?

            For incremental feedback, 6ES7138-6BA00-0BA0 accepts RS422 or 5 V TTL push-pull signals. Identify the encoder electrical interface before connecting its channels.

          • Should an RFQ for 6ES7138-6BA00-0BA0 specify encoder type or only axis count?

            Specify incremental or SSI feedback, coding and required signal rate with the complete 6ES7138-6BA00-0BA0 code. Axis count alone does not establish the required interface.

          • How can a distributor define the module-only scope of 6ES7138-6BA00-0BA0?

            List 6ES7138-6BA00-0BA0 separately from the A0 BaseUnit and encoder connection hardware. State the supplied firmware if the customer's project requires a particular version.
