Features

Four channels on DVP04DA-H3 are able to receive four pieces of 16-bit digital data from a CPU module, and convert them into analog signals (voltages or currents). Users can read data from the module or write data into the module by means of the instruction FROM/TO in a DVP-EH2/EH3 series PLC. There are 49 control registers in the module, and they are 16-bit registers. Whether the output signals are voltage outputs or current outputs depends on the wiring. The voltage output range is + - 10VDC. (The resolution is 312.5uV.) The current output range is 0~20 mA. (The resolution is 0.625uA).

Resolution	16 bits (312.5uV)	15 bits (0.625uA)
Input impedance	0.5 Ohm or below
Overall accuracy	25°C/77°F: + - 0.5% of the input within the range 0~55°C/32~131°F: + - 1% of the input within the range
Response time	1ms
Maximum output current	10mA	/
Permissible load impedance	/	0 ~ 500 Ohm
Data format	Two’s complement (16-bit data)
Isolation	The internal circuit is isolated from the analog areas, and the channels are not isolated from one another.
Protection	The voltage output is equipped with the short circuit protection. However, users must notice that a long-term short circuit will damage the internal circuit. The current output can be an open circuit.
Communication mode (RS-485)	ASCII/RTU mode Communication speed: 4,800/9,600/19,200/38,400/57,600/115,200 bps ASCII data: 7-bit, even bit, 1 stop bit (7, E, 1) RTU data: 8-bit, even bit, 1 stop bit (8, E, 1) When DVP04DA-H3 is connected to a CPU module, the RS-485 communication can not be used.
Connection with a DVP-PLC CPU	The modules are numbered according to their distances from the CPU module. The numbers start from 0 to 7. Eight modules at most can be connected, and they do not occupy digital inputs/outputs.
Rated maximum power consumption	24VDC (20.4VDC~28.8VDC) (-15% ~ +20%); 4.5W An external power supply supplies the DC voltage.
Operation/Storage	Operation: 0°C~55°C (temperature); 50~95% (humidity); pollution degree 2 Storage: -25°C~ 70°C (temperature), 5~95% (humidity)
Vibration/Shock resistance	International standards IEC 61131-2, IEC 68-2-6 (TEST Fc)/IEC 61131-2 & IEC 68-2-27 (TEST Ea)
