ET-7244 Ethernet I/O Module, 8-ch DI/DO with 2-port Ethernet Switch

ET-7044 CR is a DIN-rail Ethernet I/O module that pairs eight wet-contact digital inputs with eight sink-type digital outputs. Each input can be used as a 32-bit counter, which suits pulse counting and event tracking on machines, building services and test equipment. Each output channel can switch a 300 mA load at 25 °C, so it can drive a power relay module directly.The module communicates over Modbus TCP and Modbus UDP through a 10/100 Base-TX RJ-45 port. A built-in web server with Web HMI allows configuration and monitoring from a browser, and access is controlled by ID, password and IP filter. Dual programmable watchdogs cover the module and the communication link, and the digital outputs have programmable power-on and safe values for defined behaviour during start-up or fault conditions.Electrical isolation is rated at 1500 VDC for the Ethernet side and 2500 VDC for the I/O side. The digital inputs and outputs are not isolated from each other channel to channel. The module is powered from a +10 ~ +30 VDC terminal block with reverse polarity protection, and it operates from -25 ~ +75 °C.ApplicationsBuilding AutomationFactory AutomationMachine AutomationRemote MaintenanceRemote DiagnosisTesting Equipment

PET-7044 CR is a PoE-powered Ethernet I/O module for engineers who need eight digital inputs and eight digital outputs on a single DIN-rail unit. The inputs are wet contact type, accept +10 ~ +50 VDC as ON level and can each be used as a 32-bit counter, with a maximum count of 4,294,967,295 and a frequency of 500 Hz. The outputs are sink type, rated at 300 mA per channel at 25°C, and both their power-on value and safe value are programmable.The module communicates over Modbus TCP and Modbus UDP through a single RJ-45 10/100 Base-TX port, and can be powered from PoE (IEEE 802.3af) or from a +12 ~ +48 VDC terminal block. A built-in web server and web HMI allow configuration and monitoring without dedicated software, and access is controlled by ID, password and IP filter. Dual watchdogs cover both the module and communication.Isolation is provided as 2-way I/O isolation rated at 2500 VDC, while the channels are not isolated from each other. The unit is suited to building automation, factory and machine automation, and remote maintenance and diagnosis. The ordering code PET-7044 CR is listed as RoHS.ApplicationsBuilding automationFactory automationMachine automationRemote maintenanceRemote diagnosisTesting equipment

The PET-7244 CR is a PoE-powered Ethernet I/O module that brings eight wet-contact digital inputs and eight sink-type digital outputs onto a Modbus TCP or Modbus UDP network. Each input can also be used as a 32-bit counter, reaching up to 4,294,967,295 counts at a rate of 100 Hz, which suits pulse counting and totalising tasks.A 2-port 10/100 Base-TX switch with LAN bypass allows the module to be daisy-chained along a line of devices. It can be powered either over PoE (IEEE 802.3af, Class 1) or from a +12 ~ +48 VDC terminal block. Each output channel handles 650 mA at 25°C and is short-circuit protected, with programmable power-on and safe values so that a defined state can be set for start-up and safe conditions.A built-in web server with Web HMI, access control by ID, password and IP filter, and a dual watchdog are included. Optical isolation guards the I/O against transient overvoltage, but the channels are not isolated from one another, which should be considered during wiring.ApplicationsBuilding AutomationFactory AutomationMachine AutomationRemote MaintenanceRemote DiagnosisTesting Equipment

ET-7242 CR is an Ethernet I/O module that drives 16 sink-type digital outputs and reports their status over Modbus TCP or Modbus UDP. Its built-in web server and web HMI allow configuration and monitoring from a standard browser, which suits engineers who want to commission and check I/O without dedicated software.The built-in 2-port 10/100 Base-TX switch with LAN bypass lets the module sit in a daisy-chain topology, so cabling between I/O points can be simplified. Each output has a load voltage range of +3.5 ~ +50 VDC and up to 650 mA per channel at 25°C, and the outputs can directly drive an RM series relay module to switch inductive loads. Power-on and safe values are programmable, so outputs can be set to a defined state at start-up or on communication loss.I/O is optically isolated to 3750 VDC for transient overvoltage protection, while Ethernet is isolated to 1500 VDC. Channels are not isolated from each other. The module is DIN-rail mounted and specified for an operating range of -25 ~ +75 °C.ApplicationsBuilding automationFactory automationMachine automationRemote maintenanceRemote diagnosisTesting equipment
