DVP-EHPlatinum Temperature Sensors

Instruction Sheet

1		WARNING
	Please carefully read this instruction thoroughly prior to use the DVP04PT-H.
		In order to prevent electric shock, do not touch the terminals or conduct any maintenance while
	power to the PLC is ON. Do NOT open the PLC. Only qualified personel or Delta staff is allowed
	to conduct any internal electrical work on the PLC.
	This is an OPEN-TYPE device, and was certified to meet the IEC 61131-2 (UL 508) safety
	requirements when installed in an enclosure.
	The DVP04PT-H must be kept under the environment away from high temperatures, high
	humidity, exceessive vibration, corrosive gases, liquids, airborne dust, and metallic particles.
		Do not apply AC power to any of the input/output terminals, or it may damage the DVP04PT-H.
	Make sure that the DVP04PT-H is properly grounded		, to prevent any electromagnetic noise.
	Use wires with resistance when connect the platinum resistance thermister (RTD) to PLC.
	Please keep the wires as short as possible when connecting the RTD to PLC, and keep power
	wires as far away as possible from I/O wires to prevent noise interference.

2.1Model Explanation and Peripherals

Thank you for choosing DELTA DVP PLC Series. DVP04PT-H allows the connection of four platinum temperature sensors (PT100 3-WIRE 100 Ω 3850 PPM/°C (DIN 43760 JIS C1604-1989)). The DVP-PLC EH MPU converts the sensors input into a 14 bit digital signal, and then be manipulated by using TO and FROM instructions in the ladder logic program. There are 49 Controlled Registers (CR, each register has 16 bits) in each module.

Software version DVP04PT-H platinum temperature sensors can be updated via RS-485 communication.

DVP04PT-H displays both Centigrade and Fahrenheit. The input resolution for Centigrade is 0.1 degrees and for Fahrenheit is 0.18 degrees.
