Product Description:

The VAM42.1-PB-NF-AB-TB-NN-EE-1608-D1 is a machine operator panel produced by Bosch Rexroth Indramat within the VAM Machine Operator Panels series. It functions as a field-mounted interface that presents push-button inputs, status LEDs, and network connectivity so operators can command or monitor automated cells without opening the control cabinet. By integrating discrete I/O points and network ports in one sealed assembly, the unit simplifies the wiring needed between the supervisory PLC and the operator station.

The panel communicates with the master controller over a PROFIBUS-DP fieldbus, allowing cyclic exchange of process data at deterministic scan times. It accepts 16 digital inputs, letting sensors or selector switches be read directly by the onboard electronics, and provides 8 digital outputs for indicator lamps or interlock coils. A molded front bezel has an IP54 rating, meaning the fascia resists limited dust ingress and water splashes that are typical on factory lines. Control electronics are powered from a DC 24 V logic supply, which is a common voltage for machine safety circuits. Behind the mounting surface, the enclosure projects only 102 mm, reducing interference with adjacent devices inside crowded panels.

The housing spans 407 mm across, so adequate door space is needed when planning enclosure layouts. When mounting through the operator console, an opening that is 215 mm high and 380 mm wide aligns the clamping brackets with the unit’s rear gasket. Overcurrent protection is handled by an internal fuse rated at 3 A, matching the 1.7 A logic load and the 150 mA draw of the separate EKS Ethernet electronics that connect to the controller through an RJ45 port. Total depth, including the 70 mm front module, keeps the operator panel flush while still allowing access to the PROFIBUS connector, the 24 V terminals, and the replaceable fuse holder.
