      Information

      Overview Downloads Applications / Compatibility Product Precautions
      • Emerson 8623-FT-IS. This PAC8000 terminal connects discrete hazardous-area field signals to a matched intrinsically safe digital-input module.
      Product role: Intrinsically safe digital-input field terminal
      Matched I/O module: 8220-DI-IS, 16-channel DI
      Field channels: 16 digital-input terminations
      Field-terminal key: B / 1 with 8220-DI-IS
      The 8623-FT-IS is the 16-channel DI terminal in the PAC8000 field-terminal list. Emerson identifies 8220-DI-IS as the 16-channel intrinsically safe digital-input module, and the terminal sheet assigns connection diagram 6 to 8623-FT-IS. Each input must be checked against its own field device and channel position before the module scan is accepted.

      The approved 8220-DI-IS pairing uses field-terminal key position B/1. The terminal uses module-side multipin connectors and screw-clamp field wiring with a tagging strip. The blue terminal body identifies intrinsically safe field connections, while the separate I/O module and carrier remain necessary parts of the assembly.

      IECEx BAS 12.0023U covers the 8623-FT-IS as a 16-channel IS field terminal and limits terminal input/output voltage to 30 V. Field-device type, cable, power arrangement and certificate entity parameters must be checked as a complete loop; do not apply the RTD terminal wiring diagrams of 8626-FT-IS to this DI terminal.
      Installed-system reference: PAC8000 / 8220-DI-IS digital input. Match the DI module and 16-channel field wiring.
      Technical downloads for Emerson 8623-FT-IS: Apter Power technical reference and an Apter Power installation and commissioning guide.
      These documents are prepared by Apter Power using the identified manufacturer source. Confirm the installed 8623-FT-IS configuration with the complete manufacturer and site procedures.
      Digital-input context: 8623-FT-IS terminates up to 16 intrinsically safe discrete field channels for the 8220-DI-IS module.

      Compatibility boundary: Pair the full terminal reference with 8220-DI-IS and its B/1 key position, then follow diagram 6 and the approved IS loop design.
      Installation and commissioning checks for Emerson 8623-FT-IS.
      Isolate field circuits

      Apply the area and site isolation procedure before removing the terminal.

      Match the pairing

      Verify the 8220-DI-IS module and B/1 key before fitting the terminal.

      Use diagram 6

      Trace each assigned input conductor against the 8623-FT-IS terminal diagram.

      Assess IS voltage

      Keep the approved assembly within the certificate’s 30 V terminal limit.

      Secure conductors

      Inspect terminal screw engagement and channel tagging before service.

      Test inputs

      Prove each restored input state and the corresponding controller indication.

      Technical notes

      Module relationship: 8623-FT-IS is the 16-channel DI terminal for 8220-DI-IS; the I/O module processes the input states.

      Protection: Apply the 30 V terminal limit and the approved field-loop parameters to the complete IS installation.

      Technical reference: Emerson PAC8000 Remote I/O, 00813-0100-0108; MTL Field terminals; IECEx BAS 12.0023U.

      FAQ View All FAQ

      • Which module is specified with Emerson 8623-FT-IS?
        Emerson lists 8220-DI-IS as the matched 16-channel intrinsically safe digital-input module.
      • How many field channels does Emerson 8623-FT-IS provide?
        The terminal is identified as the 16-channel DI field-terminal variant.
      • Which connection diagram applies to Emerson 8623-FT-IS?
        The field-terminal wiring sheet assigns diagram 6 to this terminal.
      • What key position pairs Emerson 8623-FT-IS with 8220-DI-IS?
        The approved pairing uses B/1 for the field-terminal key.
      • What terminal-voltage condition applies to Emerson 8623-FT-IS?
        IECEx BAS 12.0023U limits input/output voltage at the terminal to 30 V.
      • Is Emerson 8623-FT-IS the same as 8624-FT-IS?
        No. 8623-FT-IS is the 16-channel DI terminal; 8624-FT-IS is the eight-channel loop-disconnect DI variant.
      • How are channels identified on Emerson 8623-FT-IS?
        Use the screw-clamp terminal positions and the tagging strip to map each field circuit to its DI channel.
      • What should be tested after Emerson 8623-FT-IS is replaced?
        Verify each restored field input state at the 8220-DI-IS module and in the controller against the approved loop design.
