Functional Features
The module manages remote-address handling, system initialization, and command routing within the 2400 architecture. It operates with Control Chief transmitters, receivers, relays, and machine controllers. It supports loss-of-communication monitoring where the wider system configuration enables that function.
Application Scenarios
Industrial wireless remote control for cranes, locomotives, winches, material-handling equipment, and fixed machinery requiring operator mobility away from the main controller.
Material And Structure
The unit uses a control-board assembly with system connectors, configuration hardware where fitted, and interface terminations defined by the 2400 cabinet design. Enclosure and PCB construction follow Control Chief legacy industrial standards.
Working Principle
The transmitter sends encoded command frames to the receiver system. The communication module processes addressing and protocol data, then forwards validated commands to relay or controller outputs. The machine control system executes motion, braking, or auxiliary functions according to the received commands.
Installation Requirements
Confirm 90-20-0-003 or 90200003 marking on the physical module before installation. Inspect PCB revision, connector condition, configuration switches, antenna or interface ports, and serial labels. Establish system supply only from the machine documentation. Verify ground continuity and protection-device condition before live operation.
Usage Precautions
Do not energize the module in an unknown 2400 configuration. Perform communication initialization, transmitter identification, command-response, and loss-of-signal recovery tests before connecting to cranes, locomotives, or hoists. Record all hardware revisions and return defective discontinued modules to qualified repair inventory only.
