Allen-Bradley 1492-GM35 Group Marker Carrier

The Allen‑Bradley 1492‑GM35, also cataloged as the 1492‑GM35 marker‑carrier accessory, operates as a DIN‑rail mounted labeling component for conductor and terminal‑block identification across Bulletin 1492 wiring platforms.

Hardware Specifications

Profinet / EtherNet/IP Deterministic Networks

Marker carriers contribute to stable wiring organization in Allen‑Bradley control panels. Clear labeling reduces routing ambiguity and supports consistent shield‑termination practices for Profinet and EtherNet/IP deterministic networks. Mechanical stability on 35 mm DIN rails helps maintain conductor strain‑relief patterns and minimizes transient disturbances on high‑speed industrial Ethernet cabling.

Frequently Asked Questions

Q: Can the marker carrier be used with mixed terminal‑block families? A: Yes. It is compatible with multiple 199 and 1492 DIN‑rail profiles.

Q: Does the carrier provide electrical isolation? A: No. It is a mechanical labeling accessory only.

Q: Is the label surface protected? A: Yes. Raised edges on three sides help shield the written or printed label.

Field Installation Guidelines

• Mount the carrier on the designated DIN‑rail section before installing terminal blocks.
• Ensure label surfaces remain unobstructed for clear identification.
• Maintain conductor routing to avoid lateral pressure on the marker carrier.
• Verify rail compatibility (199‑DR and 1492‑DR series) before installation.
• Keep labeling consistent with panel documentation to support maintenance workflows.
