Analog Input to RS485 Converter

Product Description

Features2-channel Single-ended InputsVoltage Inputs and Current InputsAdjustable Sampling RateDual WatchdogIntroductionThe tM-AD2 is an analog input module that includes 2 single-ended analog input channels and provides a programmable input range on all analog inputs (0 500 mV, 0 1 V, 0 2.5 V, 0 5 V, 0 10 V, 0 20 mA, 4 20 mA). It provides high overvoltage protection of 120 VDC. The sampling rate of the tM-AD2 is adjustable and is available in either fast or normal mode. It also provides 4 kV ESD protection as well as 2500 VDC intra-module isolation.ApplicationsIndustrial AutomationIndustrial MachineryBuilding AutomationFood and Beverage SystemsSemiconductor FabricationControl SystemsCPU ModuleWatchdog TimerModule, Communication (Programmable)IsolationIntra-module Isolation2500 VDCEMS ProtectionEFT (IEC 61000-4-4)4 kV for PowerESD (IEC 61000-4-2)4 kV Contact for Each Terminal8 kV Air for Random PointLED IndicatorsStatus1 x Power and CommunicationAnalog InputChannels2 Single-endedTypeVoltage,CurrentRange0 500 mV, 0 1 V, 0 2.5 V, 0 5 V, 0 10 V, 0 20 mA, 4 20 mAResolutionNormal Mode: 14-bitFast Mode: 12-bitAccuracyNormal Mode: 0.1%Fast Mode: 0.5%Sampling RateNormal Mode: 10 HzFast Mode: 200 HzInput ImpedanceVoltage: 10 MCurrent: 125 Overvoltage Protection120 VDCOvercurrent Protection50 mA at 110 VDCIndividual Channel ConfigurationYesOpen Wire DetectionYesCOM PortsPorts1 x RS-485Baud Rate1200 115200 bpsData Format(N, 8, 1), (N, 8, 2), (O, 8, 1), (E, 8, 1)ProtocolDCON, Modbus RTU, Modbus ASCIIPowerReverse Polarity ProtectionYesConsumption0.7 W Max.Powered from Terminal Block10 30 VDCMechanicalDimensions (mm)52 x 98 x 27 (W x L x H)InstallationDIN-Rail MountingEnvironmentOperating Temperature-25 +75 CStorage Temperature-30 +75 CHumidity10 95% RH, Non-condensing
