K336 - Lincoln Electric NA-5 Remote Interface Module K336

Lincoln Electric K336 Remote Interface Module for NA-5 Controls

The Lincoln Electric K336 Remote Interface Module is a specialized accessory designed to expand the operational capabilities of NA-5 automatic welding controls. In complex industrial environments where the power source and control unit may be positioned at a distance from the immediate welding operator or automation interface, this module serves as the critical link. It is engineered to permit the remote operation of four specific functions: inch up, inch down, start, and stop. By integrating this module, facilities can streamline their workflow, allowing operators to adjust wire positioning and initiate weld cycles from a convenient remote location without needing to access the main control panel directly.

A primary technical advantage of the K336 is its ability to provide electrical isolation. It effectively isolates the sensitive NA-5 control circuitry from the external signals used for remote operation. This isolation is crucial for protecting the main control unit from potential electrical noise, ground loops, or voltage spikes that might occur in the external switching wiring. The module is versatile in its signal acceptance, accommodating two distinct methods of actuation. It can be triggered by the momentary closure of switches rated for 24 volts at 5 milliamperes DC. Alternatively, it accepts 24-volt signals, specifically the momentary application of a 24-volt (±10%) AC or DC signal capable of a 5-milliampere steady state. This flexibility allows integrators to use a wide range of standard industrial switches, PLCs, or relay logic to interface with the welding system.

The K336 is designed to be backward compatible and replaces the earlier version of the K336 Remote Pushbutton Interface Module, which was limited to external switch closure signals only. The updated module's ability to handle active voltage signals makes it far more adaptable to modern automated systems where active logic outputs are common. Physically, the unit is compact, measuring approximately 3.25 inches in height, 6.38 inches in width, and 9.25 inches in length, with a net weight of just 1 pound. This small footprint ensures it can be mounted easily within control cabinets or at operator stations without consuming excessive space. Whether you are upgrading an existing NA-5 setup or configuring a new automatic welding cell, the Lincoln Electric K336 ensures reliable, isolated remote command execution.
