Wiring connection
The following describes a connection example of Digital Input / Output Relay Interface.
CAUTION
If an inductive load (relay coil) or a bulb is connected, a surge voltage or rush current will be generated. Take adequate
measures against surge voltage or rush current.
Shield earthing
• The RS-485 communication cable must be earthed on Smart BMS Manager. It does not have to be earthed on
Digital Input / Output Relay Interface. The shielded wire must be crimped with closed end connector. The
shielded wire end must be insulated and left open.
Connection of external digital inputs
• Input circuit examples are shown below (electrically isolated using a photo-coupler).
CAUTION
• Output sink current has polarity.
When they are connected to inappropriate input terminal, the unit may not operate properly.
Connection of external digital outputs
• Output circuit examples are shown below (open collector output electrically isolated using a photocoupler).

Power supply
The RS-485 communication cable must
be earthed on Smart BMS Manager. It
does not have to be earthed on Digital
Input / Output Relay Interface.
Set the Digital Input / Output Relay
Interface address with SW1. Assign 1 to 8
to each address to avoid duplication. You
can set the Digital Input / Output Relay
Interface address independently from the
Energy Monitoring Relay Interface
address.
CAUTION: The SW1 setting is read when
the power is turned on. Push the reset
switch (SW6) after changing the address.
Set the RS-485 terminator resistor on an
Energy Monitoring Relay Interface.
Set SW7 as "120 ohm" on a Digital Input /
Output Relay Interface with address
SW1=1, when the Digital Input / Output
Relay Interface is used in a system without
Energy Monitoring Relay Interface. Set
SW7 as "Open" on the other interfaces.
The RS-485 signal
wire has polarity A
and B. Be careful
when connecting
the wire.

6Setting
The following settings are necessary to use Digital Input / Output Relay Interfaces.
• SW1 Address set switch
When two or more Digital Input / Output Relay Interfaces are used, set a different address for each unit
to avoid address duplication.
Assign addresses in ascending order.
CAUTION
•When the SW1 setting has been changed, push the reset switch SW6. The new address setting is read.
•Address of Digital Input / Output Relay Interface can be set independently from Energy Monitoring Relay
Interface.
• SW2 Operation mode set switch
• SW3 Test switch
• SW4 Test switch
These switches are not used during normal operation. Set zero (0) or “all
OFF”.
• SW6 Reset switch
When performing an address setting with SW1, push this reset switch after the address setting to read
the set value.
• SW7 RS-485 terminator resistor select switch
Terminator resistor of RS-485 must be set on Energy Monitoring Relay Interface.
When Digital Input / Output Relay Interface is used without Energy Monitoring Relay Interface, set it
[120 ohm] on Digital Input / Output Relay Interface with address SW1=1 and, set it [Open] on the other
Interfaces.

7Test run
Before starting test run
Turn on the power of the Digital Input / Output Relay Interface after all cable connections and settings are
completed. Turn on power of the air conditioning control system.
Test run
Confirming external input connection
• In the test mode, when the external inputs connected to the input terminals DI-1 to DI-8 are ON, the respective
LEDs will goes on so you can confirm the connection.
▼Confirming procedure:
1Set the operation mode switch SW2 to “3”, and push the reset switch SW6 to enter the test mode.
2Unless SW4 is pushed, the respective input status of DI-1 to DI-4 is indicated by LED2 to LED5.
3When SW4 is pushed, the respective input status of DI-5 to DI-8 is indicated by LED2 to LED5.
(*) To return to the normal operation, reset SW2 to “zero (0)” and push SW6.
Checking external output connection
• In the test mode, you can set output terminals DO1 to DO4 to ON or OFF with the test switch. Their output status
is indicated by each LED.
▼Checking procedure:
1Set the operation mode switch SW2 to “3” in the same way as the external input check, and then
push the reset switch SW6 to enter the test mode.
2When the bit of the test switch SW3 is set to ON, the external output turns ON; when set to OFF,
the external output turns OFF. Bits 1 to 4 of SW3 correspond to output terminals DO1 to DO4.
The respective output status of output terminals DO1 to DO4 is indicated by LED6 to LED9.
The LEDs light with the output ON, and goes off with the output OFF.
(*)To return to normal operation, reset SW2 to “zero (0)” and push SW6.
