OCS Connector
The switcher is supplied a 3.81mm 3-pole 90° Reversed Gender Plug Phoenix
®
connector which is used for
connecting an occupancy sensor.
The first pin is a 24V logic input. The default state is high. Different type of sensors exist: some send high
level, some send low level to this input when the room is occupied. Active-high or active-low logic might be
configured for this port in LDC to support them.
The second pin has a constant 24V output voltage and the third one is the ground
.

OCS connector pin assignments
Voltage ranges for 1nd pin are the following:
Input voltage
[V]
Logic low level
0 - 0.8
Logic high level
2V- 24V
OCS Output Voltage Level: 24V (50mA).
Pull-up resistor is integrated on the input. Works automatically with open-drain type sensors. Requires an
external 1kR pull-down resistor between input and ground pins when used with active-high type sensors.
In case of applying Leviton OCS (

external resistor between the 1st and the 3rd pins is necessary.
Compatible Plug Type
WR-TBL series (3.81mm 3-pole 90° Reversed Gender Plug Phoenix), type: WR-TBL Series 3483 - 3.81 mm.
ATTENTION!
Occupancy sensor connector and GPIO port are not compatible with each other because of
the voltage level difference, please do not connect them directly.

GPIO - General Purpose Input/Output Ports
The switcher is supplied a 8-pole Phoenix connector with six GPIO pins, which operates at TTL digital signal
levels and can be set to high or low level (Push-Pull). The direction of the pins can be input or output (adjustable).
Voltage ranges for GPIO inputs are the following:
Input
