M6330: Control Unit with II/O Lightbus Connection
The M6330 control unit is fitted with a choice of switching elements. Switch
positions are read via the II/O Lightbus, and indicator lights are driven by
the central controller.
Some of the switching elements are wired to screw terminals, to control, for
instance, emergency off switches or a main contactor.
- Stackable 8 * 4 keypad to be fitted with a choice
of keyswitches, indicator lights, emergency off
switches etc.
- 32 electromechanical illuminated switches, wired
to the II/O Lightbus as make contact inputs and
indicator light outputs, of which 8 are additionally
wired as changeover contacts to screw terminals
- Keys and switching elements: Manufactured by
Schlegel
- In aluminium housing (M6330)
or as built-in panel (M6331)
- optionally with 32 keys (M6330-000),
with 31 keys + emergency off (M6330-001),
without keys (M6330-010),
or customer-specific (M6330-030)

Mechanical Features
- External dimensions of aluminium diecast housing: 240 * 160 * 117 mm, type ROLEC
- Built-in panel: External dimensions of built-in plate: 243 * 134 mm
Hole required: 216 * 108 mm, page 2
- If the rear of the device will no longer be accessible after assembly, making it mechanically necessary to
plug in the connecting strip before the built-in panel is fitted, the hole needs to be 226 * 108 mm large.
An appropriate drawing can be requested.
- Mounting depth: 78 mm under the front panel
- Key arrangement: see page 1
- Protection type: for version mounted in housing, IP65 on all sides
for built-in panel, IP65 to the front
- Fitting to customer-specific housings is a possible option
Fittings
- All actuators in the SCHLEGEL OKTRON range that can be combined with normal contact makers can be
used
- Key cap colours optionally white, green, yellow, blue or red
- Marking with standard symbols using ready-made labelling inserts or blank inserts for special signs
General Electrical Properties
- 32 electro-mechanical keys from the SCHLEGEL OKTRON series, illuminated, pre-wired as make contact.
The upper 8 keys are optionally connected to a terminal strip for 24 V wiring. They are pre-wired as
changeover contacts. One of these keys is wired specially (to a single-terminal connection) for an
emergency off function
In 24 V applications the 8 switches are electrically galvanically isolated from the electronics
- Power supply 24 V DC, 400 mA + 30 mA per lamp

Wiring Instructions
- The upper row of keys is configured for 5 V operation as standard. Operation with 24 V is possible
without modification. It should be noted here that the working voltage is brought to contact 13/21 of the
changeover switch, and the related load is connected to the make contact 14 and/or to the break contact
22.
- All 4 contacts on the optional EMERGENCY OFF switch are accessible at the terminal strip. If, for a special
application, the 5 V supply at contact 13.0 is not desired, it can be disconnected by opening a soldering
jumper. The position of the soldering jumper on the board can be seen in the diagram on page 3.
The make contact 14.0 remains connected to input D0.0, while break contacts 21-22 are available and
without voltage.
II/O Lightbus Telegram Assignments
The two modules are to be connected in series. The output from module A is usually connected to the input
of module B. This means that module A is to be entered first in the S1000 software II/O setup.
The tables on the following page apply to both of the modules.
