Chapter 2 Specifications and System Configuratio n 2.4 Analog Input/Output Module Specifications 2.4.1 General Specifications DVP04AD-E2 Electrical specifications 2_ Things to note when connecting the module to a CPU PLC module: 1. Up to 8 modules can be connected to a CPU PLC module. 2. The connected module is numbered automatically from 0 (nearest to the CPU PLC module) to 7 (furthest away from the CPU PLC module). 3. The connected modules do NOT take up any digital I/O points.

K1 ~ K100 Self-diagnosis function Detecting if exceeding upper and lower limts or channel disconnection 25° C/77° F: The allowed error range is ±0.5% of full scale. 0° C to 55° C/-32° F to 131° F: The allowed error range is ±1% of full scale. Overall Accuracy An analog circuit is isolated from a digital circuit by a digital integrated circuit/an optocoupler, but the analog channels are not isolated from one another. Isolation between a digital circuit and a ground: 500 VDC Isolation between an analog circuit and a ground: 500 VDC Isolation between an analog circuit and a digital circuit: 500 VDC Isolation between the 24 VDC and a ground: 500 VDC Isolation
