Product Description:

The BTM04.1-NA-TA-TA-VB-2FF-FW is an operator panel produced by Bosch Rexroth Indramat as part of the BTM04 Machine Operator Panels series. It serves as the local human-machine interface on CNC systems and automated assembly lines. Operators can access motion commands, override functions, and emergency stop control from one front-mounted unit. Its layout supports routine production tasks and direct machine interaction without relying on a separate desktop interface.

The panel’s emergency stop circuit uses 2 NC contacts that open the safety chain when pressed, and the button returns to service with a Twist Unlock action that helps prevent accidental resets. Feed-rate adjustment is digitized through a rotary switch that transmits a 5-Bit Gray Code to the controller. Because only one bit changes between successive positions, the controller can detect each step with reduced risk of input errors. Three status indicators backlight the override knob, and the count of these indicators is 3, matching the number of dedicated override pushbuttons that increment, decrement, or acknowledge the selected value. A membrane keypad provides momentary contacts, and the figure 15 indicates how many discrete keys are available for program selection, jog commands, or auxiliary functions without an external keyboard.

The enclosure carries 4 module slots arranged from left to right as an Emergency Stop Module, two Key Pad Modules, and a Feed Override Module. All wiring from these sections is collected on the master board, which supplies 16 optically isolated inputs and the same number of transistor outputs for lamp or relay drive. This arrangement keeps signal connections centralized on the panel instead of distributing them across the front modules. The housing has a Powder Coated finish that resists scratches and solvents, and a front gasket seals the assembly to IP65. That sealing helps block dust and low-pressure water jets during use on machine fronts, pendants, or gantries in typical shop-floor environments.
