Product Description

Features16 Differential Analog InputsCurrent, Voltage, and Thermocouple InputsAdjustable CJC offsetOpen Thermocouple DetectionBuilt-in Dual WatchdogIntroductionThe M-7018-16 is a 16-channel differential analog input module that supports current, voltage, and thermocouple input. The voltage input range can be from 15 mV to 2.5 V, and the current input range can be either +4 to +20 mA, 0 to +20 mA, or 20 mA, and types J, K, T, E, R, S, B, N, C, L, M, LDIN43710 thermocouple can be used for the thermocouple input. Overvoltage protection of up to 30 VDC is provided. The module also features per-channel open wire detection for the thermocouple input types and provides 4 kV ESD protection as well as 3000 VDC intra-module isolation.Applications Building Automation Factory Automation Machine Automation Remote Maintenance Remote Diagnosis Testing EquipmentCPU ModuleWatchdog TimerModule, Communication (Programmable)IsolationIntra-module Isolation3000 VDCEMS ProtectionEFT (IEC 61000-4-4)4 kV for Power LineESD (IEC 61000-4-2)4 kV Contact for Each TerminalSurge (IEC 61000-4-5)2 kV for Power LineLED IndicatorsStatus1 x Power and CommunicationAnalog InputChannels16 DifferentialTypeVoltageCurrentThermocoupleSensor TypeThermocouple: J, K, T, E, R, S, B, N, CRangeVoltage: 15 mV, 50 mV, 100 mV, 500 mV, 1 V, 2.5 VCurrent: 20 mA, 0 +20 mA, +4 +20 mA (requires an optional external 125 resistor)Resolution16-bitAccuracy0.1% of FSRSampling Rate10 Hz (Total)Input Impedance> 400 kCommon Voltage Protection25 VDCOvervoltage Protection30 VDCOpen Wire DetectionFor Thermocouple OnlyCOM PortsPorts1 x RS-485Baud Rate1200 115200 bpsData Format(N, 8, 1), (N, 8, 2), (E, 8, 1), or (O, 8, 1)ProtocolModbus RTU, DCONPowerReverse Polarity ProtectionYesInput Range+10 +30 VDCConsumption0.5 WMechanicalDimensions (mm)76 x 120 x 42 (W x L x H)InstallationDIN-Rail MountingEnvironmentOperating Temperature-25 +75 CStorage Temperature-40 +85 CHumidity10 95% RH, Non-condensing
