PET-7042 PoE I/O Module, 16-ch Sink-Type Digital Output

The ET-7042 CR is an Ethernet I/O module that switches 16 sink-type digital outputs over a single 10/100 Base-TX RJ-45 port. Each output is an isolated open collector rated from +5 to +30 VDC, with up to 100 mA per channel at 25°C. Power-on and safe values for the outputs are programmable, so the module can drive known states when the network or host is unavailable.Communication uses Modbus TCP or Modbus UDP, and the built-in web server provides a Web HMI for setup and monitoring without additional software. Access control is handled through ID, password and IP filtering. A module watchdog and a communication watchdog, both programmable, help maintain safe operation, and the I/O pair connection feature is available.Isolation is rated at 1500 VDC on the Ethernet side and 2500 VDC on the I/O side. There is no channel-to-channel isolation. The module can drive the RM series relay modules directly to switch inductive loads. It is powered from +10 to +30 VDC through a terminal block with reverse polarity protection, draws 2.7 W maximum, and mounts on DIN rail.ApplicationsBuilding automationFactory automationMachine automationRemote maintenanceRemote diagnosisTesting equipment

ET-7042-UT CR is a DIN-rail Ethernet I/O module that switches 16 isolated open-collector digital outputs in sink configuration. Each channel handles a load voltage of +5 ~ +30 VDC and up to 100 mA at 25°C, so it can drive loads directly or feed an RM series relay module when switching inductive loads.The module is aimed at engineers who need remote, networked output control without a local PLC. It supports Modbus TCP and Modbus UDP, and includes a built-in web server with web HMI for configuration and monitoring. Access is restricted by ID, password and IP filter, and a dual watchdog helps the output stage return to a defined state after faults.Power-on and safe values for the digital outputs are programmable, which allows each installation to define the state of its outputs at start-up and during communication loss. The listed operating range of -40 ~ +75°C suits cabinets in demanding environments, with 2500 VDC I/O isolation and 1500 VDC Ethernet isolation.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

The ET-7242-UT is an Ethernet-connected I/O module providing 16 isolated open-collector sink-type digital outputs. Each channel carries up to 650 mA at 25°C and can directly drive a power relay module, which is useful when switching inductive loads.The built-in web server and Web HMI let engineers configure and monitor the module from a browser, while Modbus TCP and Modbus UDP provide host communication. The integrated 2-port 10/100 Base-TX switch with LAN bypass supports daisy-chain wiring. Dual watchdogs for the module and communication are programmable, and the power-on and safe values of each digital output can be set.Optical isolation is rated at 3750 VDC on the I/O side and 1500 VDC on the Ethernet side. ESD, EFT and surge protection are specified to IEC 61000-4-2, -4-4 and -4-5. The module is rated for -40 to 75 °C operation and mounts on DIN-rail.ApplicationsBuilding AutomationFactory AutomationMachine AutomationRemote MaintenanceRemote DiagnosisTesting Equipment

PET-7242 CR is a PoE-powered Ethernet I/O module that switches 16 sink-type digital outputs and reports them over Modbus TCP or Modbus UDP. Each channel is an isolated open-collector output rated at 650 mA per channel at 25°C, and the outputs can drive an RM series relay module directly, which suits switching inductive loads.Output behaviour is configurable, with a programmable power-on value and safe value for each channel. The module provides overvoltage, overload and short-circuit protection. A 2-port 10/100 Base-TX switch with LAN bypass supports daisy-chain topologies, and a dual watchdog supervises both the module and the communication link.The unit includes a built-in web server with web HMI and access control based on ID, password and IP filter. It can be powered from PoE (IEEE 802.3af, Class 1) or from a +12 ~ +48 VDC terminal block, and is rated for -25 ~ +75 °C operation. Certification marks listed for this model are CE, UKCA, FCC, RoHS and WEEE.ApplicationsBuilding AutomationFactory AutomationMachine AutomationRemote MaintenanceRemote DiagnosisTesting Equipment
