          PRODUCT DESCRIPTION

          8C-PDIPA1 51454471-375 Digital pulse input module

          Honeywell 8C-PDIPA1 51454471-375 is a coated Series 8 digital input and pulse accumulation module for Experion LX. Its 32 inputs accept 24 V DC field signals, with the first sixteen channels individually selectable for discrete input or pulse counting and frequency measurement.

          Optical isolation separates the input circuitry from the control electronics when external field power is used. The module handles pulses up to 1 kHz with a minimum 30% duty cycle and uses a 300 µs channel scan; nonredundant and redundant IOTA arrangements provide alternative field termination configurations.

          SYSTEM & REPLACEMENT CHECK

          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 8C-PDIPA1 51454471-375 within Experion LX Series 8

          Configure channels 1–16 individually as digital inputs or pulse accumulation points; channels 17–32 remain digital inputs. Match pulse scaling and frequency settings to the transmitter, including the 300 µs minimum pulse width and minimum 30% duty cycle.
          Use the 8C-TDILA1 IOTA for a nonredundant arrangement or 8C-TDILB1 for redundancy. Select internal or external field power deliberately; the specified 1000 V AC system-to-field isolation requires an external user-supplied field source.
          Allow 105 mA for the module and keep external field power between 18 and 30 V DC. Verify ON and OFF levels, channel diagnostics and count continuity before accepting the pulse measurements into the control strategy.

          Features:

          • Input channels: 32
          • Pulse-capable channels: 1–16
          • Experion LX Series 8
          Use 8C-PDIPA1 51454471-375 only within the documented Experion LX Series 8 arrangement and applicable installation instructions.
          INTERCHANGEABILITY

          Replace 8C-PDIPA1 51454471-375 within Experion LX Series 8

          Record the complete 8C-PDIPA1 and 51454471-375 identification together with the installed IOTA. Preserve the channel-by-channel DI/pulse assignments and the redundant or nonredundant configuration before removing the existing module.
          Check whether field power is supplied internally or externally and retain the same approved grounding and isolation arrangement. A replacement must preserve the pulse frequency, width, input impedance and threshold requirements, rather than simply matching the number of terminals.
          The Series 8 specification supports removal and insertion under power within the applicable installation procedure. After exchange, check module health, all discrete states and pulse totals, including the behavior of the redundant path where fitted.

          Features:

          • Input channels: 32
          • Pulse-capable channels: 1–16
          • Experion LX Series 8
          Use 8C-PDIPA1 51454471-375 only within the documented Experion LX Series 8 arrangement and applicable installation instructions.

          Questions buyers ask about 8C-PDIPA1 51454471-375

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

          • Which inputs can count pulses on 8C-PDIPA1?

            Channels 1–16 can be assigned individually to pulse accumulation or digital input; channels 17–32 are digital inputs.

          • What pulse waveform does the Series 8 module accept?

            The 8C-PDIPA1 specification permits 0–1 kHz, a minimum 30% duty cycle and pulse widths of at least 300 µs.

          • Does field isolation depend on the power selection?

            Yes. The 1000 V AC RMS system-to-field isolation specification applies when external field power is used.

          • Which IOTA gives redundant pulse input termination?

            8C-TDILB1 is the redundant IOTA; 8C-TDILA1 is the nonredundant IOTA for 8C-PDIPA1.

          • Can 5 V be treated as a guaranteed ON signal?

            No. For 8C-PDIPA1, 5 V DC is the maximum OFF threshold; the minimum ON voltage is 13 V DC.

          • What must be checked after changing a pulse input module?

            Verify DI/pulse assignments, count continuity, channel diagnostics and the configured redundant path before relying on the measured totals.

          • What should a distributor retain in the 51454471-375 quotation?

            Keep both 8C-PDIPA1 and 51454471-375, the IOTA number, quantity and redundancy requirement. State separately whether the IOTA is included.

          • Are pulse transmitters and IOTAs included with the module?

            They are separate components unless expressly listed in the written offer. Confirm the exact 8C-PDIPA1 supply scope and dispatch date before ordering.
