and use.
Common Sense for Safe Use
1. Please read the product manual carefully before using the product;
2. For products that are not ready to be installed and used, anti-static protection should be done well
(preferably placed in an anti-static protective bag, do not take it out);
3. Before taking out the product, place your hands on a grounded metal object to release static electricity
from your body and hands, wear electrostatic gloves and wristbands, and develop the habit of only
touching the edges;
4. In order to avoid electric shock to the human body or damage to the product, the power must be cut off
every time the product is unplugged or reconfigured;
5. Before moving the product, be sure to cut off the power supply;
6. For the complete machine, be sure to power off when adding/reducing boards;
7. Before you need to connect or unplug any equipment, make sure that all power cords have been
unplugged in advance;
8. In order to avoid unnecessary damage to the product caused by frequent switching on and off, after
switching off, wait at least 30 seconds before switching on.

1 Product Description
1.1 Overview
DAM-3028MC is 8-channel isolated digital input and 8-channel C-type signal relay output module,
and it supports RS485 communication interface and standard ModbusRTU protocol. It is equipped with a
good human-computer interface, so it is easy to use and its performance is stable.

Note：
1. Resistive Load: The maximum value of all parameters of the relay is realized when the load is
resistive load. Resistive load means the load that iodine tungsten lamp, incandescent lamp, resistance
furnace, oven, electric water heater, etc. will not cause voltage and current phase changes.
2. Contact Maximum Switching Voltage: This value is the maximum value when the load is a
resistive load, and supports DC and AC voltage. If the load is a capacitive load or an inductive load,
this indicator may be reduced.
3. Data Communication Rate: This parameter refers to the communication speed between the MCU
controller and the host computer, which belongs to the theoretical maximum value. The
communication rate will also be affected by the length of the field wiring, the number of loaded
modules, the programming architecture of the host computer, and the hardware capabilities of the
CPU.

3、Power and Communication Line Connection
The power input and RS485 communication interface are shown in the figure below. The maximum
voltage of the input power supply is 30V. Exceeding the range may cause permanent damage to the module
circuit.

4、INIT Mode Description
Short-circuit the INIT* pin and the GND pin, and apply +10~+30VDC voltage between the +Vs
terminal and the GND terminal. After power-on, the module indicator flashes 3 times quickly. After the
indicator stop flashing, the module has completed reset. Power off and power on, the module restores the
factory settings. The default factory settings see the 2.4 Default factory state.
Figure 5
5、Indicator Light Description
Running indicator: When the power is normally on and no data is sent, the indicator is always on;
when there is data transmission, the indicator flashes; When INIT is short-circuited and powered on, the
indicator light flashes 3 times quickly.

The configurable range is
0~0xFFFFFFFF. When it is
configured to any
value greater
than 0, the module will increase
the number of the phase set on the
originally set number of pulse
outputs. When the module is in
continuous output mode, this
operation does not work. . When
configured as 0, the number of

pulse output by high 16 bits
