The exact FPR3316101R1032 listing identifies the unit as an ICSI16E1 binary input unit, while the more detailed technical listing specifies sixteen 24 VDC isolated inputs and a configurable 2–32 ms input delay.
ABB documentation also lists ICSI16E1 among the CS31 Series input modules, confirming its position within the Procontic CS31 I/O family.
Product Introduction
The ABB ICSI16E1 FPR3316101R1032 is a 16-channel binary input unit used with ABB Procontic CS31 control systems. Its primary job is to collect discrete 24 VDC field states such as limit switches, auxiliary contacts, proximity devices, and other on/off signals and make those states available to the controller.
For maintenance engineers, the important characteristics are the 16-channel configuration, 24 VDC input level, electrical isolation, and configurable input delay. These details affect how field devices are wired and how short pulses or contact transitions are interpreted by the controller.

Application Scenarios & Field Pitfalls
Engineering Pain Point
Replacing an older input unit is rarely just a matter of matching the ICSI16E1 family name. ABB documentation and supplier catalogs show multiple ICSI16E1 references and electrical variants, so the complete FPR number should be treated as the primary procurement identifier.
Typical Applications
- Discrete machine feedback — limit switches, auxiliary contacts, interlocks, and position signals.
- Process equipment monitoring — binary status signals from field instruments and equipment.
- remote/local I/O — collection of discrete field states for ABB Procontic controllers.
- Legacy plant control — maintenance of established ABB installations where replacing the complete control architecture is not practical.
Technical Pitfalls to Avoid
- Do not assume every ICSI16E1 has the same electrical specification.
The family appears with different FPR numbers. One supplier identifies another reference, FPR3316101R0034, with a different voltage description, while FPR3316101R1032 is specifically listed as the 24 VDC version. Match the complete FPR number rather than the shortened model name. - Do not publish 220 VAC operation for R1032 without verification.
Several reseller pages incorrectly combine 220 VAC specifications with the name. The exact R1032 evidence supporting this page identifies it as a 24 VDC input unit. - Check the input-delay setting when troubleshooting fast signals.
The documented 2–32 ms configurable delay can affect short pulses and contact transitions. A replacement with a different setting may appear electrically healthy while producing different PLC input behavior.

Procurement and Replacement Notes
For ICSI16E1 FPR3316101R1032, use FPR3316101R1032 as the critical ordering identifier rather than purchasing solely against .
Before installation, verify:
- Complete FPR number and nameplate revision
- 24 VDC field-input requirement
- Sixteen-channel wiring
- Input isolation
- Configured input-delay setting
- Existing controller and I/O architecture
- Terminal arrangement and field wiring
- Application documentation and PLC input mapping
Important identification note: is a family designation, not sufficient by itself to establish the electrical variant. The available documentation shows other FPR numbers associated with , so should not be casually substituted with FPR3316101R0034 or another variant.
