Digital I/O Module

Product Description

FeaturesSource-type Digital Output with Overload ProtectionDigital Input Channels Can be Used as 16-bit CountersShort Circuit ProtectionConfigurable Power-on Value and Safe Value SettingsIntroductionThe M-7055/M-7055D offers 8 isolated channels for digital input and 8 isolated channels for digital output. Either sink- or source-type inputs can be selected via wire connections. All digital input channels are also able to be used as 16-bit counters. The M-7055(D) supports source-type output with short circuit protection. The M-7055D has 16 LED indicators for channel status monitoring. The M-7055(D) supports Modbus RTU and DCON protocols, which can be configured via software. There are also options for configuring power-on and safe values. 4 kV ESD protection and 3750 VDC intra-module isolation are standard, and all hardware specifications are the same as the I-7055(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 Communication8 x Digital Input8 x Digital OutputDigital Input/CounterChannels8TypeDry Contact,Wet ContactSink/Source (NPN/PNP)Sink/SourceON Voltage LevelDry: Close to GNDWet: +10 +50 VDCOFF Voltage LevelDry: OpenWet: +4 VDC Max.Max.
