The PX232 Relay Module is a device used to switch effects of stage and architectural illuminators
via DMX-512 signal.
The module contains a transmitter that controls the on / off output. It has a built-in hysteresis,
which eliminates vibration of relay phenomena during switching on and off. The PX232 switches
on output when the DMX value is over 191. Relay switches off the output after reaching 64 value
or below.
Method of hysteresis operation is shown below.
The device is equipped with DMX signal input and output. Its housing is adapted for mounting on
DIN rails and is 35 mm wide (the size of 2-modules).
1. GENERAL DESCRIPTION
2. SAFETY CONDITIONS
The PX232 is a device powered directly from power grid 230V, what may result in electric shock
in case of not following safety rules. During its installation and use the following rules must be
strictly observed:
1. Installation of the device should be carried out by a person with appropriate qualifications in
accordance with this document.
2. The electrical outlet to which the switch is connected have to be linked to a working protective
installation (3-wire installation.)
3. Protect the power cord from mechanical and thermal damage.
4. In case of damage the power cord, cable, replace it with the same technical data and
certificates.
5. For connecting devices to the 1 Relay Module use only 3-wire cables with cross-section of not
less than 1.5 mm.
6. Connection of DMX signal can only be made with shielded conductor.
7. All repairs and connections of outputs or DMX signal can only be made with cut off power
supply.
8. PX215 should be strictly protected against contact with water and other liquids.
9. All sudden shocks, particularly dropping, should be avoided.
10. The device cannot be turned on in places with humidity exceeding 90%.
