………………………………………………………………… ENGLISH …………………………………………………………………

Thank you for choosing Delta’s DVP series PLC. DVP04AD-E2 analog input module receives external 4 points of analog input signals (voltage or current) and converts them into 16-bit digital signals. You can select voltage input or current input by the wiring. In addition, you can access the data in the module by applying FROM/TO instructions or read the average value of channels directly by using MOV instruction (Please refer to allocation of special registers D9900 ~ D9999).

This instruction sheet provides only information on the electrical specification, general functions, installation and wiring. For detailed program design and applicable instructions, please refer to “DVP-ES2 Operation Manual: Modules”. For details of the optional peripheral, please refer to the instruction sheet enclosed in the package.

This is an OPEN TYPE I/O module and therefore should be installed in an enclosure free of airborne dust, humidity, electric shock and vibration. The enclosure should prevent non-maintenance staff from operating the device (e.g. key or specific tools are required for operating the enclosure) in case danger and damage on the device may occur.

DO NOT connect the input AC power supply to any of the I/O terminals; otherwise serious damage may occur. Check all the wiring again before switching on the power. Make sure the ground terminal is correctly grounded in order to prevent electromagnetic interference.

Note 1: When performing analog input, please isolate other power wirings.

Note 2: When the A/D module is connected to current signals, make sure you short-circuit “V+” and “I+” terminals.

Note 3: If the noise is too significant, please connect FE to the grounding terminal.

Note 4: Please connect the terminal on both the power module and A/D module to the system earth point and ground the system contact or connect it to the cover of power distribution cabinet.

Note 5: 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.

Explanation on Special Registers D9900~D9999

When DVP-ES2 MPU is connected with modules, registers D9900~D9999 will be reserved for storing values from modules. You can apply MOV instruction to operate values in D9900~D9999.

When DVP-ES2 MPU is connected with DVP04AD-E2, the configuration of special registers is as below:

	Module	Module	Module	Module	Module	Module	Module	Module		Description
	#0	#1	#2	#3	#4	#5	#6	#7
	D1320	D1321	D1322	D1323	D1324	D1325	D1326	D1327	Model Code
	D9900	D9910	D9920	D9930	D9940	D9950	D9960	D9970	CH1 average
									input value
	D9901	D9911	D9921	D9931	D9941	D9951	D9961	D9971	CH2 average
									input value
	D9902	D9912	D9922	D9932	D9942	D9952	D9962	D9972	CH3 average
									input value
	D9903	D9913	D9923	D9933	D9943	D9953	D9963	D9973	CH4 average
									input value

Note 1: D9900 ~ D9999 are average input values of CH1 ~ CH4 and the sampling range is K1 ~ K100. When the sampling range is set to K1, the values displayed in D9900~D9999 are current values. You can use: 1. ES_AIO Configuration Function of WPLSoft or 2. FROM/TO instructions (CR#8

~CR#11) to set the sampling range as K1.

Adjust A/D Conversion Curve

Users can adjust the conversion curves according to the actual needs by changing the Offset value (CR#28 ~ CR#31) and Gain value (CR#34 ~ CR#37).

Gain: The corresponding voltage/current input value when the digital output value = 16,000.

Offset: The corresponding voltage/current input value when the digital output value = 0. y Equation for voltage input Mode0 / Mode2: 0.3125mV = 20V/64,000 = 10V/32,000

	X (V )		(Gain −Offset )
Y =16000 ×		×32000 −Offset
	10(V )		Y=Digital output, X=Voltage input

yEquation for voltage input Mode1 / Mode3: 0.15625mV = 10V/64,000 = 5V/32,000
