Product Description:

The BTM04.1-NA-TA-VA-SA-2EA-FW is a machine operator interface produced by Bosch Rexroth Indramat and supplied within the BTM04 Machine Operator Panels series. Designed for mounting on machining centers or production lines, the panel houses push-buttons, signal lamps, and data connectors. It allows commands to be entered, alarms to be acknowledged, and spindle and feed functions to be supervised from a single location. This layout keeps control, indication, and connection points together on one panel face for straightforward machine access.

At the rear of the housing, two 24 V supply lines are accepted through connector X28/X29, providing isolated low-voltage power for lamps and logic boards. A powder-coated surface shields the aluminum front plate from abrasion and coolant mist. The main board is equipped with 16 dedicated I/O slots, so field signals such as limit switches or sensor contacts can be wired directly without additional terminal blocks. Four removable module bays, indicated by a slot count of 4, allow specialized circuitry to be added while keeping the footprint unchanged. For installation in washdown areas, the front seal and gasket carry a protection rating of IP65, preventing dust ingress and water jets from reaching the electronics.

In operation, the panel can be populated with function inserts for Emergency Stop, writable keyboard, feed, and spindle, allowing machine-specific layouts without changing the wiring harness. Diagnostic data is routed through the rear X8 serial port, which sits on its own slot to avoid crosstalk with field wiring. As a compact Machine Operator Panel, the unit provides direct local control while maintaining deterministic response for CNC-related functions. The design used by Bosch Rexroth Indramat keeps core power, communication, and safety circuits on separate pluggable boards.
