Compatibility & Replacement

01

Original-System Compatibility

Read by an IMMFP01/02 or IMLMM02 over the slave expander bus using FC84. Manufacturer documentation lists NTDI01/NIDI01 termination and NKTU01, NKTM01 or NKTU02 cable arrangements. Inputs 7/8 and 15/16 share commons by pair and must use the same voltage source.

02

Historical Replacement

ABB identifies SPDSI22 as the Harmony Rack replacement. The later SD-series path depends on voltage class (DI01/DI02/DI03/DI04); no single SD module covers every mixed high- and low-voltage combination.

04

Applications & Fault Scenarios

  • Contact status, limit switches, relay feedback, breaker position, alarms and permissive/interlock inputs.
  • Systems combining 24 VDC logic with 125 VDC or 120 VAC plant indications, subject to the documented common-pair restriction.
  • Maintenance searches commonly involve missing slave, wrong FC84 address, fast/slow response selection, incorrect voltage jumper, shared-common wiring or field leakage.
  • A missing input group can block starts or create an unsafe status ambiguity; FC84 failure behavior must be understood before online replacement.
05

Configuration & Installation

  • Set the module address to match FC84 and select the voltage and response jumpers for each input.
  • Inputs 7/8 and 15/16 share common positive connections by pair; each pair must be supplied from the same voltage source.
  • The manufacturer manual permits insertion/removal with rack power applied, but field energy and site procedures must still be controlled.
06

Failure Behavior & Diagnostics

  • A module-address or expander-bus mismatch is reported as a missing slave.
  • FC84 specification S3 determines the documented response to a slave failure: trip the master when set to 0, or continue operation when set to 1.
  • Use the 16 front LEDs, controller point quality and measured field voltage together to separate input-module, termination and field-device faults.
07

Maintenance

  • Every six months or during shutdown, inspect signal, power and ground connections and clean dust with static-safe vacuum equipment.
  • Copy all address and voltage/response jumper settings before fitting a replacement.

FAQ

01How should IMDSI02 be installed?
Match the FC84 address and every voltage/response jumper, observe the shared-common pairs, and connect the specified termination and cable. Control field energy under the site's electrical-safety procedure even when rack hot insertion is permitted.
02Can SPDSI22 replace IMDSI02?
ABB identifies it as the Harmony Rack replacement. Confirm the field-voltage schedule, shared commons, termination, address and controller database before migration.
03What should be configured for IMDSI02?
Set the module address, per-input voltage and fast/slow response selection, and review FC84 specification S3 because it determines whether the master trips or continues after a slave failure.
04How should IMDSI02 be maintained and protected from ESD?
Use a grounded wrist strap and antistatic packaging. At scheduled maintenance, check field and ground connections, remove dust with static-safe equipment and compare LED, controller and measured-voltage status.
05What delivery and warranty support is available for IMDSI02?
Each unit is function-checked where suitable test facilities are available and packed in an antistatic bag with protective cushioning. DOA, return and exchange requests are handled under the written order terms after evidence and technical evaluation. Warranty covers confirmed supply defects during the agreed period, excluding misuse, incorrect installation, ESD damage, improper storage and unauthorized repair.
06What information is needed for an IMDSI02 RFQ?
Please provide the Part Number, Quantity, Destination, Required Date and Machine/System Model. Include the field-voltage list, controller, FC84 address and termination number where possible.

Technical statements are limited to verified ABB/Bailey manufacturer documentation. Installation must follow the plant safety procedure and the documentation for the installed system revision.
