16 Ch Digital Input Module

Product Description

Features16 Digital InputsDry Contact and Wet Contact Selectable via Wire ConnectionsPhotocoupler IsolationLong Distance MeasurementAll Channels Can be Used as 16-bit CountersBuilt-in Dual WatchdogIntroductionThe M-7051/M-7051D offers 16 channels for digital input, catering for both dry and wet contact, with an effective distance of up to 500 meters for dry contact. All channels not only feature photocoupler isolation but also be used as 16-bit counters. The M-7051D has 16 LED indicators for channel status monitoring. The M-7051(D) supports Modbus RTU and DCON protocols, which can be configured via software. 4 kV ESD protection and 3750 VDC intra-module isolation are standard, and all hardware specifications are the same as the I-7051(D).Applications Building Automation Factory Automation Machine Automation Remote Maintenance Remote Diagnosis Testing EquipmentCPU ModuleWatchdog TimerModule, Communication (Programmable)DisplayTypeI/O LED IndicatorIsolationIntra-module Isolation3750 VDCEMS ProtectionEFT (IEC 61000-4-4)4 kV for Power LineESD (IEC 61000-4-2)4 kV Contact for Each Terminal8 kV Air for Random PointSurge (IEC 61000-4-5)3 kV for Power LineLED IndicatorsStatus1 x Power and Communication16 x Digital InputDigital Input/CounterChannels16TypeDry Contact,Wet ContactSink/Source (NPN/PNP)Sink/SourceON Voltage LevelDry: Close to GNDWet: +10 +50 VDCOFF Voltage LevelDry: OpenWet: +4 VDC Max.Max.
