IR-310-RM, IR Controlled 10-ch High Power Relay Module (Ver. 1.5, Oct/21/2020) 4

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.

Firmware update mode (FW).

Figure 2-12: JP5 setting for Firmware Update

2.6.1 Update firmware mode

Set the JP5 to “FW” position and power cycle the IR-310-RM to enable the firmware
update mode. At the same time the power LED blinks rapidly 4 times per second. In
the FW mode, you have to use RS-232 port to update firmware by the Firmware
Update Tool. Please click the menu of IR-310-RM utility [Tool] -> [Firmware Update
Tool] to launch the firmware update tool. According to the following steps, you can
finish the update firmware procedures in the Fig. 2-13.

(1) Select “COM” and “COM Port”
(2) Click “Browser” to select the firmware file (ir310rm_v#_#_#.fw).
(3) Click “Firmware Update” to start the update procedure.

Note:

1. Use RS-232 port to update firmware.

2. After updating firmware, remember to change the JP5 to the “OP” position and
power cycle the IR-310-RM to run in the operation mode.

The firmware of IR-310-RM can be downloaded from:

http://www.icpdas.com/en/download/index.php?model=IR-310-RM/

Firmware_Update_Tool can be launched from the IR utility:

2.6.2 Normal Operation Mode

Set the JP5 to the “OP” in figure 2-11 and power cycle the IR-310-RM to enable the
Normal Operation Mode.

2.7 LED Indicators

There are two kinds of LEDs for IR-310-RM to indicate several states.

(1) Power LED :

The PWR LED is ON to indicate the IR-310-RM is turned on.

2.8 DIP Switch

There four states of the 2-pin dip switch which represent four modes for IR-310-RM as
shown in table 2-5. To take effect the setting, please power cycle the module after set
the dip switch.

(4) Emitting built-in IR commands mode (corresponding to built-in IR-Relay-States)

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.

3. Configuration and Control on IR-310 -RM

There are two ways to configure and control IR-310-RM. One is the easy IR-310-RM
utility for test and settings and the other is the Modbus/RTU commands for the Modbus
master.

Please refer to chapter 4 and 5 to learn the IR-310-RM utility and the Modbus
commands.
