Compatible Replacement & Equivalent Models
If the IBS RT 24DI/16-T is discontinued, long lead-time, or outside budget, the following models offer functional equivalence or drop-in compatibility within the PHOENIX CONTACT Interbus ecosystem:
- IBS RT 24DI/16-T-LK – Identical channel count; enhanced locking connector variant
- IBS ST 24DI/16-T – Inline station variant; same 16-channel 24 VDC DI specification
- IBS IL 24DI/16-T – Inline (IL) series equivalent; compatible with Interbus IL topology
- IBS RT 24DI8/8DO8-T – Mixed I/O alternative when output channels are also required
- Third-party Interbus DI modules – Modules from Weidmüller or Turck with Interbus compatibility may serve as functional replacements; verify protocol version and connector pinout before substitution
Contact [email protected] for cross-reference verification before ordering a replacement.

Selection Guide
Use the table below to select the correct PHOENIX CONTACT IBS RT digital input module for your application:
- 16 DI, 24 VDC, screw terminal → IBS RT 24DI/16-T ✓ (this model)
- 16 DI, 24 VDC, spring-clamp terminal → IBS RT 24DI/16-T-SC
- 8 DI + 8 DO, 24 VDC → IBS RT 24DI8/8DO8-T
- 32 DI, 24 VDC → IBS RT 24DI/32-T
- 16 DI, 120 VAC input → IBS RT 120DI/16-T
Key selection criteria: channel count → input voltage → terminal type → bus segment position → environmental rating (IP20 vs IP67).

Replacement & Compatibility FAQ
Q: Can I replace IBS RT 24DI/16-T with an IBS ST 24DI/16-T?
A: Functionally yes — both are 16-channel 24 VDC DI Interbus modules. The ST series uses a different housing form factor; verify DIN rail space and connector type before substitution.
Q: Is this module compatible with Siemens S7-300?
A: Yes, when used with a PHOENIX CONTACT IBS S7 300 DSC/I-T Interbus master card installed in the S7-300 rack.
Q: What is the maximum number of IBS RT 24DI/16-T modules per Interbus segment?
A: Up to 32 remote bus devices per segment, subject to the 512-point I/O limit of the Interbus master.
Q: Do you supply the original PHOENIX CONTACT datasheet?
A: Yes — email [email protected] with your order number or inquiry and we will provide the official PDF datasheet and wiring diagram.
Q: Can Konmask.com source discontinued or long-lead-time units?
