1. Introduction
IR-310-RM is a 10-channel high power relay module designed for the power switching
control of the appliances. The relay module can switch up to 10 A loads. There are
NO/NC contacts and protection circuit for each channel. The channels can be
controlled independently or sequentially by serial communication with Modbus RTU
protocol, as well as by wireless IR remote control. There are also maximum 5
interlocked relay pairs for interlocked switching. The application field can be
manual/automatic power switch, timer switch, light scenario control and energy
conservation etc.

Built-in IR commands are the IR commands corresponding to the built-in 10 relay
states (Refer to appendix A). In this mode, IR-310-RM will emit IR commands #192
~ #203 sequentially from the IR output channel. The flowchart of this process is
depicted in figure 2-16. Users can set the IR learning remote control in the learning
mode to learn these IR commands for test as shown in figure 2-17.

4.2.3 Relay Output Section
‧ Current 10 relay states indication
This section (figure 3-8) shows the current 10 relay output states after connection
between utility and IR-310-RM is established. Relay ON and OFF means the normally
open (NO) and normally closed (NC) of the relay’s contact.
‧ Control 10 relay states for test
Change the ON/OFF state of relays by clicking the circles.
‧Interlocked mode
There are maximum 5 interlocked relay pairs which can be set on IR-310-RM. They
are RL0/RL1, RL2/RL3, RL4/RL5, RL6/RL7, and RL8/RL9. The interlocked relay pairs
are effective when the “Enable Interlocked Mode” checkbox is checked and set.
There are three states for an interlocked relay pairs (e.g. for RL0/RL1):
(1) RL0 is OFF; RL1 is OFF.
(2) RL0 is ON; RL1 is OFF.
(3) RL0 is OFF; RL1 is ON.
Being ON state of both relays is not allowed in a relay pair.

4.2.6 Power on value and power failure memory section
If the “Enable Power Failure Memory” is not set, IR-310-RM applies the Power On
Value settings of 10 relay states. Otherwise, the 10 relay states of power failure
memory are used when power is on.
Radio buttons Forward/Stop of power on value are for the forward/stop action in
sequential mode.
Latency (sec) is the delay time to record the 10 relay states after the relay states are
changed. The default is 1800 sec (30 min) and the minimum is 5 sec.
Figure 4-7: Power on value and power failure memory section.
4.2.7 IR Sensor Selection section
There are three selections of IR sensor sources can be set.
(1) On-board IR sensor: The sensor is located in the front panel.
(2) IR Receiver Cable: Use “IR Output” channel. CA-IR-001 needs to be
plugged into the “IR Output” jack (3.5 mm audio jack).
(3) No sensor: Disable the IR remote function.

4.2.8 Emit IR Commands section
Custom and built-in IR commands are available for IR remote control on the IR-310RM. Each IR command is for an IR-310-RM with specific Modbus Net ID and the
corresponding IR-relay-state configured in the section of Relay States Corresponding
to IR cmds (Section 4.2.9).
Plug the IR emitter cable CA-IR-SH2251-5 in the jack of IR Output at the rear of the
IR-310-RM. Click the “Emit IR Command” button will emit an IR command. Users can
aim the head of the IR emitter cable to the IR receiver of the IR-310-RM for test. This
function is for the IR learning remote to learn the IR commands for the IR-310-RM
module.

5. Modbus Commands for IR-310-RM
The following Function Code commands are provided for a Modbus master to control
and configure IR-310-RM. It is necessary to append 2 bytes of CRC16 to the tail of
each Modbus command.
FC01, 05, and 15 are the standard Modbus commands for Modbus masters to access
the relay outputs of IR-310-RM. Sub-FC commands of FC100 are specific to the
settings and control on IR-310-RM.

There are “preset power-on values” mode and “power failure memory” mode to set
relay states after power restoration. Power failure memory mode records the 10 relay
states after the change of the relay states occurs and the latency is up. This is useful
for some application such as lighting control after the power restoration.

Appendix B: INIT Mode
If users forget the communication settings (e.g. baud rate, software Net ID) of IR-310RM, push the DIP switch to the “Init” position and reset the module to run the Init mode.
In this mode, IR-310-RM applies the default communication settings.
