Product Description:

The VAM81.1-USB-UF-TA-TA-VE-MA-NNNN operator panel is produced by Bosch Rexroth Indramat within the VAM Machine Operator Panels series. It is a handheld human-machine interface intended for machine tools, packaging lines, and other automated stations where local control and immediate feedback are required. The panel includes hard-wired emergency, stop, and mode buttons, along with an incremental encoder, so operators can jog axes, set reference points, or acknowledge alarms while remaining close to the machine.

Its electronics are supplied from a 24 V DC ±20% source that enters through a 2-pin, 3.5 mm plug-in power connector, and under normal operation the board draws a nominal current of 0.3 A. The internal regulator feeds the signal sections, which provide 16 bits of safe extra-low-voltage extended inputs and 8 bits of matching extended outputs. These channels allow the panel to read auxiliary sensors or drive indicator lamps without routing every signal through the main control cabinet. Each output line can source up to a maximum of 100 mA max, which is suitable for small relays or LED indicators. Four stop-switch pins provide a dedicated loop for compatible safety circuits, and four labeling strips allow clear text identification for the operator keys.

For precise feed adjustment, the integrated handwheel accepts encoder pulses over a cable length of up to 3 m max and evaluates them through a differential input stage that improves noise immunity near high-power drives. The wheel’s emitter receives a 5 V supply and transmits quadrature A/B TTL signals to the control through an open-collector output. All handwheel leads terminate in a 25-pin D-SUB connector, which keeps the connection point compact and organized. A front-mounted USB-A port allows parameter files to be transferred without opening the enclosure.
