MQTT I/O (MQ-7200M)
The MQ-7244M is an Ethernet I/O module for engineers who need to connect digital sensors and switches to MQTT or Modbus TCP systems without a separate gateway. It combines 8 digital inputs with 8 digital outputs in one metal housing, and the built-in web server lets you configure the unit, check network and I/O status, and switch outputs from a standard browser on a PC or mobile device.A 2-port 10/100 Base-TX switch with LAN bypass allows the module to be daisy-chained along a machine or panel, which simplifies cabling where several I/O points are spread out. Each output channel is rated at 650 mA at 25°C, and both the power-on value and the safe value can be programmed, so outputs can be set to a defined state on start-up or during a fault.Optical isolation rated at 2500 VDC for transient overvoltage protection is provided, although the digital outputs are not isolated from one another channel to channel. Dual watchdogs for the module and communication support fault recovery in unattended installations. The unit mounts on a DIN rail or on a wall.ApplicationsBuilding AutomationFactory AutomationMachine AutomationRemote MaintenanceRemote DiagnosisTesting Equipment
The MQ-7251M brings 16 wet-contact digital inputs onto an Ethernet network, publishing their states over MQTT 3.1 or Modbus TCP for IIoT and automation systems. Its inputs accept sink or source wiring, so the module suits a wide range of digital sensors and switch contacts.Configuration and monitoring are handled through a built-in web server with a web-based HMI, which can be opened in a standard browser on a computer or mobile device to check network connection status and I/O state. A 2-port 10/100 Base-TX switch with LAN bypass allows modules to be daisy-chained along a cable run, and dual watchdogs cover both the module and communications.The module is housed in a metal casing and can be mounted on a DIN rail or on a wall. It is powered from +12 ~ +48 VDC with reverse polarity protection, and is rated for an operating temperature of -25 ~ +75 °C. Optical isolation provides 2500 VDC transient overvoltage protection, but there is no channel-to-channel isolation.ApplicationsBuilding AutomationFactory AutomationMachine AutomationRemote MaintenanceRemote DiagnosisTesting Equipment
The MQ-7252M is an Ethernet I/O module that links digital sensors and actuators to IIoT platforms and supervisory systems over MQTT 3.1 or Modbus TCP. It provides 8 digital inputs and 8 digital outputs in a single DIN-rail or wall-mounted unit, so it can handle common discrete monitoring and switching tasks without a separate controller.Configuration, network status monitoring and I/O status checks are handled through a built-in web server and web HMI, which can be opened in any standard browser on a computer or mobile device. The same interface can be used to switch individual digital output channels manually. Each output channel can drive up to 650 mA, and the power-on and safe values are programmable.The integrated 2-port 10/100 Base-TX switch, with LAN bypass, allows devices to be daisy-chained along a network run. Optical isolation of 2500 VDC transient overvoltage protection is provided, although there is no channel-to-channel isolation. The module is suited to applications where hazardous voltages may be present.ApplicationsBuilding automationFactory automationMachine automationRemote maintenanceRemote diagnosisTesting equipment
The MQ-7253M brings 16 dry-contact digital inputs onto an Ethernet network and exchanges I/O data over MQTT 3.1 or Modbus TCP. It suits engineers connecting digital sensors into IIoT systems that need remote monitoring of switch states.A built-in web server and web HMI let you configure the module and check network connection status and I/O status from a standard browser on a computer or mobile device. The 2-port 10/100 Base-TX switch with LAN bypass supports daisy-chain wiring, and dual watchdogs (module and communication) are provided.Inputs are optically isolated with a 1500 VDC isolation rating and 2500 VDC transient overvoltage protection, but there is no channel-to-channel isolation. The module can be used where hazardous voltages are present. The ordering description identifies this variant as RoHS-compliant.ApplicationsBuilding AutomationFactory AutomationMachine AutomationRemote MaintenanceRemote DiagnosisTesting Equipment
The MQ-7255M is an Ethernet I/O module for IIoT installations that need to connect digital sensors and switches to a network using MQTT or Modbus TCP. It provides 8 digital inputs that accept both dry and wet contacts, and 8 digital outputs of the source type.An integrated web interface lets you configure the module, check network and I/O status, and switch digital outputs from a standard browser on a computer or mobile device. The built-in 2-port switch with LAN bypass allows the module to be daisy-chained along a network run, which simplifies cabling in distributed installations.Each output channel handles up to 650 mA at 25°C, with programmable power-on and safe values. The module offers optical isolation and dual watchdog protection, and is housed in a metal casing for DIN-rail or wall mounting. The MQ-7255M CR ordering code covers this RoHS-compliant configuration.ApplicationsBuilding AutomationFactory AutomationMachine AutomationRemote MaintenanceRemote DiagnosisTesting Equipment
The MQ-7260AM CR is an Ethernet I/O module for connecting digital sensors and switching loads in IIoT installations. It combines six digital inputs, which accept both dry and wet contacts, with six Form A power relay outputs, and reports status over MQTT 3.1 or Modbus TCP.A built-in web server provides a browser-based interface, accessible from a computer or mobile device, for configuring the module, monitoring network and I/O status, and switching relay outputs. A 2-port 10/100 Base-TX switch with LAN bypass supports daisy-chain wiring, and dual watchdogs (module and communication) are available for supervision.The module offers optical isolation with 3000 VDC transient overvoltage protection, but there is no channel-to-channel isolation. For inductive loads, fit a flyback diode on DC circuits or a metal oxide varistor on AC circuits to protect the relay contacts and extend relay life.ApplicationsBuilding AutomationFactory AutomationMachine AutomationRemote MaintenanceRemote DiagnosisTesting Equipment
