Allen Bradley 1336-GM2 Serial Communication Module Adapter

Configured for serial bus communication and network integration within 1336 Adjustable drive systems, the Allen Bradley 1336-GM2 (1336-GM2 Serial communication module adapter) provides direct physical and electrical execution across compatible adjustable frequency drive platforms.

Hardware Specifications

Profinet / EtherNet/IP Deterministic Networks and Bus Communication

The 1336-GM2 establishes reliable multi-drop communications between variable frequency drives and external supervisory architectures. Backplane bus communication velocities are maintained via dedicated hardware slot attachment near the host control board, mitigating signal attenuation and preserving data packet integrity. Environmental parameters, including ambient atmosphere pollution levels and humidity caps up to 95% non-condensing, must be continuously evaluated during commissioning to prevent localized corrosion or capacitive degradation on internal circuit traces. Firmware flash compatibility and communication register mappings are handled via standardized adapter profile handshakes, sustaining deterministic response cycles across connected node architectures without impacting primary drive motor control loops.

Frequently Asked Questions

Q: What precautions must be observed during the physical installation of the 1336-GM2 module?

A: Technicians must strictly avoid electrostatic discharge (ESD) by wearing grounded wrist straps and handling the card exclusively by its non-conductive edges.

Q: Does the 1336-GM2 require an independent external power supply?

A: No. Operating power is supplied directly from the host drive's internal DC power rails through the dedicated internal mounting port interface.

Q: How does the discontinued lifecycle status affect replacement availability?

A: Although the manufacturer has obsoleted the part, certified third-party suppliers maintain fully tested surplus and refurbished replacement units to support legacy system lifecycles without forcing complete migration.

Field Installation Guidelines

1. Verify that the host drive is completely isolated from power sources, locked out, and fully discharged of internal capacitor voltages prior to handling.
2. Inspect the installation area near the main control board to ensure atmospheric pollution and relative humidity levels remain within specified thresholds (0 to 95% non-condensing).
3. Ground personnel using an ESD strap and carefully extract the 1336-GM2 module from its anti-static packaging.
4. Mount the internal card securely into the designated adapter slot near the host drive control board, ensuring zero loose cabling or mechanical stress on pins.
5. Inspect all connections, restore drive enclosure panels, and energize the system while observing module diagnostic indicators for correct operational handshake.
