Junction Box
Climax 2 Channel Micro Relay is designed basically to be
installed in a junction box behind a two channel contact Keypad.
The product size must be considered when applying it in
junction boxes.
Product Size: 50L X 44W X 25.7H (mm)
Screw Mounting
Screw the 2 Channel Micro Relay to any surface through 2 side
screw holes.
For screw mounting following part number must be used:
CL-PK-MR2-S

Change Device Address
The device address can be set from 0 to 31 by mean of a dip switch called
“address selector switch”. Before changing address the main power must be
disconnected. The address must be defined in binary. For instance for setting
address to “21” the address selector switch must be as bellow:
Never set the address to 0 and 1 as 0 is not valid in C-Bus protocol and 1 is
always dedicated for RS-232 GatewayPro module. Check all C-Bus modules
address to avoid repetitive address allocation.
Channel Toggling
Each channel can be toggled by connecting/disconnecting COM & corresponding
input on control pins.
Module LED’s
Upon connecting the main power, the green Power LED will start flashing.
The green Status LED flashes any time a valid data packet received to the micro relay.
In case of receiving invalid data packet in C-Bus connections, the Status LED will turn
on for 5 seconds.
At the time of connecting modules to each other Status LEDs might be turned on for 5
seconds while it must not be considered as an error.
Before wiring the device, always unplug the main power.
Before adding a new module on the C-Bus, ensure the previous module has a valid address
and is working properly.
In case of using capacitive or inductive loads, permissible current is less than normal mode
(resistive load) depending on load condition.
Follow the diagram below in order to apply right input/output and connect modules to
each other.
