• Digital IO interface: PIN 1 to 3 is a dry contact output interface with complementary functions of normally open and normally closed. PIN2 is the common end of dry contact. Dry contact output capacity: 1A/30VDC or 0.15A/220VAC; PIN 5 to 6 are dry contact input interfaces, which can be set for external control of the output, external fault feedback, or external control of the buzzer;
• Analog interface: Analog interface is optional, and interface signals can be customized, two analog interface definitions as shown in the table above
• RS485 interface: Serial communication interface(Female), software using standard Modbus-RTU protocol;
• CAN interface: CAN1 and CAN2 are two internal parallel CAN bus interfaces, which facilitate the serial or parallel connections between devices. CAN communication also be used for communication between external devices;

Note: Analog interface is an optional interface (customizable), up to a maximum of four analogs, two analog input, and two analog output. Select 1-2 analog, interface see figure above; select 3-4 analog, the interface is RJ45-CAN1, 1-8 pin is defined as the positive and negative of analog input 1, the positive and negative of analog input 2, the positive and negative of analog output 1, the positive and negative of analog output 2. If you need an analog function, please inform us of the specific requirements in advance。

Voltage compensation

Figure 3: Schematic diagram of voltage compensation wiring

To use the remote voltage compensation function, use twisted-pair cables with high insulation. Positive and negative cables can not be connected inversely, as shown in the figure above. When not in use, the compensation terminals (SENSE) PIN1 and PIN2, PIN3, and PIN4 need to be shorted with short cables.

Parallel connection

The device identifies and controls the parallel output through CAN communication. The diagram above shows the parallel connection.
Note:120 ohm is the CAN bus terminal resistor.

Front panel

Display area

The Home displays real-time operating status information of the device, including:

• Display area: Current real-time output information;
• Setting area: setting of voltage, current, and power reference values, And voltage/current priority Settings;
• Status area: buzzer, lock key state, date and time information, working time, and dry contact and application mode state (gray);
• Mode area: Control mode and output mode;
• Series/parallel status area: when multiple machines are used in series/parallel, each device will display the master/slave machine number and CAN data receiving and receiving the status of the machine (gray);

Note:

1. Display elements of the status area can be hidden. When an application mode is enabled, the status of the application mode will be displayed, and when the dry contact is used, the corresponding status icon will be displayed.
2. Output mode is divided into common mode and application mode. 1. Common mode: CV(Constant voltage), CV(Constant current), CP(Constant power), or CV/CC/CP  (Output is not open); 2. Application mode: such as CV Steps(Constant voltage steps), CC Steps(Constant current steps), and Hybrid steps in step mode.

Home

Three Homes, including:

• Home: displays the most comprehensive real-time working status information,
  detailed in the section of “Display Area”;

• Auxiliary Home: maximizes the real-time output information;

• Waveform Home: displays output real-time information in an intuitive waveform
  manner.

Note

1. The Home is the only interface for setting voltage, current, and power reference values.
2.  Press “ENTER” to set the sampling rate of the waveform displayed on the waveform Home. Whether the voltage, current, and power waveform are displayed can be controlled by pressing the “VOLT”, “CURR” or “POWER” key.
