TelemotiveGXZ304 Output Module for Industrial Radio Remote Control Receiver, Board E7650-55

Product Description

What this part is

A Telemotive GXZ304E7650 output module, marked E7650-55. Telemotive builds industrial radio remote control systems: the transmitter a crane operator carries and the receiver mounted on the crane, hoist or machine. This module is the output stage inside that receiver. Once the receiver has decoded a valid command off the air, the output module closes a contact to the machine’s control circuit, energising a motion contactor, a brake, a hoist direction or an auxiliary function. It is not a PLC I/O card, it does not decode the radio signal by itself, and it functions only inside a Telemotive receiver.

Decoding the part number

GXZ304 is the Telemotive module family this card belongs to. Other functions share the GXZ304 prefix with different trailing numbers; GXZ304E7123 is a communication module. The prefix identifies the family and the trailing number identifies the function. E7650 is the specific output module. The -55 suffix is the board-level revision or configuration marking found on the card itself. Telemotive radio controls are part of Magnetek, within Columbus McKinnon, where the modern equivalents and documentation for the line sit. Legacy GXZ hardware is a surplus and repair item.

Radio control on a crane

Radio remote control on lifting equipment is safety-relevant, and the output stage is where that shows. The output module is the last link between an operator’s thumb on a pushbutton and a contactor closing on a hoist motor. These systems are built so that a lost radio link, a low battery or an internal fault drops the outputs rather than holding them.

Published specifications

Function: output module for an industrial radio remote control receiver. Family: Telemotive GXZ304 module series. Board marking: E7650-55. Output type: switched contact outputs to the machine control circuit. Form factor: plug-in module for the Telemotive receiver enclosure. Typical equipment: overhead cranes, hoists, and mobile and process machinery under radio control. Brand lineage: Telemotive, now part of Magnetek / Columbus McKinnon.

Mounting data

The receiver’s control circuit is typically live at line-derived control voltage. Radio receiver enclosures are densely wired and the terminal assignments are function-specific. The module carries jumper or address links that are specific to the receiver configuration.

Quantity and configuration

One output module. Not included: the receiver enclosure, receiver logic and radio boards, transmitter or pendant, batteries and charger, antenna and antenna hardware, interconnecting wiring, terminal blocks, contactors, and system documentation.

Interchange guidance

The family and the full number both determine interchange. Other GXZ304 modules are different functions: GXZ304E7123 is a communication module, not an output module, and the two are not interchangeable despite the shared prefix. Modules from later Telemotive generations, such as the inteleSmart TR12 and TR24 receivers, are different hardware and do not retrofit into GXZ-era receivers. Also written GXZ304-E7650, GXZ 304 E7650, GXZ304E7650-55, E7650-55, E765055, and listed under the Telemotive, Magnetek and Columbus McKinnon names.
