DELTA DVP04DA-H2 Analog Output Module

Warning

• DVP04DA-H2 is an OPEN-TYPE device. It should be installed in a control cabinet free of airborne dust, humidity, electric shock and vibration. To prevent non-maintenance staff from operating DVP04DA-H2, or to prevent an accident from damaging DVP04DA-H2, the control cabinet in which DVP04DA-H2 is installed should be equipped with a safeguard. For example, the control cabinet in which DVP04DA-H2 is installed can be unlocked with a special tool or key.
• DO NOT connect AC power to any of I/O terminals, otherwise serious damage may occur. Please check all wiring again before DVP04DA-H2 is powered up. After DVP04DA-H2 is disconnected, Do NOT touch any terminals in a minute. Make sure that the ground terminal on DVP04DA-H2 is correctly grounded in order to prevent electromagnetic interference.

Introduction

• Model Explanation & Peripherals 
  • Thank you for choosing Delta DVP series PLC. The data in DVP04DA-H2 can be read or written FROM/TO instructions given by the program of DVP-EH2 series MPU. The analog signal output module receives 4 groups of 12-bit digital data from PLC MPU and converts the data into 4 points of analog signals for output in either voltage or current.
  • You can select voltage or current output by wiring. Range of voltage output: 0V ~ +10V DC (resolution: 2.5mV). Range of current output: 0mA ~ 20mA (resolution: 5μA).
• Product Profile (Indicators, Terminal Block, I/O Terminals)

External Wiring

• Note 1: When performing analog output, please isolate other power wirings.
• Note 2: If the ripples at the loaded input terminal are too significant that causes noise interference on the wiring, connect the wiring to 0.1 ~ 0.47μF 25V capacitor.
• Note 3: Please connect the terminal on both the power modules and DVP04DA-H2 to the system earth point and ground the system contact or connect it to the cover of power distribution cabinet.
• Note 4: If there is much noise, please connect the terminal FG to the ground terminal.
• Warning: DO NOT wire empty terminals .

Output mode setting

| Reserved| CH4| CH3| CH2| CH1
Output mode: Default = H’0000 Mode 0: Voltage output (0V ~ 10V) Mode 1: Voltage output (2V ~ 10V)

Mode 2: Current output (4mA ~ 20mA)

Mode 3: Current output (0mA ~ 20mA)

CR#1: The working mode of the four channels in the analog input module. There are 4 modes for each channel which can be set up separately. For example, if the user needs to set up CH1: mode 0 (b2 ~ b0 = 000); CH2: mode 1 (b5 ~ b3 = 001), CH3: mode 2 (b8 ~ b6 = 010) and CH4: mode 3 (b11 ~ b9 = 011), CR#1 has to be set as H’000A and the higher bits (b12 ~

b15) have to be reserved. Default value = H’0000.

CR#18 ~ CR#27: Please note that: GAIN value – OFFSET value = +400LSB ~ +6,000 LSB (voltage or current). When GAIN – OFFSET is small (steep oblique), the resolution of output signal will be finer and variation on the digital value will be greater. When GAIN – OFFSET is big (gradual oblique), the resolution of output signal will be rougher and variation on the

digital value will be smaller.

Error status

See the table of error status for more information.

---|---|---|---|---|---
CR#30: Error status value (See the table below)

Note: Each error status is determined by the corresponding bit (b0 ~ b7) and there may be more than 2 errors occurring at the same time. 0 = normal; 1 = error.

Example: If the digital input exceeds 4,000, error (K2) will occur. If the analog output exceeds 10V, both analog input value error K2 and K32 will occur.

Return to default; OFFSET/GAIN tuning authorization

| Reserved| CH4| CH3| CH2| CH1
Default = H’0000. Take the setting of CH1 for example:

1.  When b0 = 0, the user is allowed to tune CR#18 (OFFSET) and CR#24 (GAIN) of CH1. When b0 = 1, the user is not allowed to tune CR#18 (OFFSET) and CR#24 (GAIN) of CH1.

2.  b1 represents whether the OFFSET/GAIN tuning registers are latched. b1 = 0 (default, latched); b1 = 1 (non-latched).

3.  When b2 = 1, all settings will return to default values. (except CR#31, CR#32)

CR#33: For authorizations on some internal functions, e.g. OFFSET/GAIN tuning. The latched function will store the

output setting in the internal memory before the power is cut off.

Ex: To setup 8N1 for RTU (High/Low Bit Exchange of CRC), communication speed is 57600 bps, write H’C310 in CR #32.
*Note 1. Supports ASCII mode ONLY.
CR#0 ~ CR#34:** The corresponding parameter addresses H’4032 ~ H’4054 are for users to read/write data by RS-485 communication. When using RS-485, the user has to separate the module with MPU first.

1. Function: H’03 (read register data); H’06 (write 1 word datum to register); H’10 (write many word data to register).
2. Latched CR should be written by RS-485 communication to stay latched. CR will not be latched if written by MPU through TO/DTO instruction.
