PET-7252 PoE Ethernet I/O Module, 8-ch DI / 8-ch DO, 2-port Switch

The PET-7250A is a networked I/O module from the ET-7000/ET-7200 range, designed to be controlled remotely over Ethernet using Modbus TCP or Modbus UDP. It suits engineers integrating field signals into HMI, SCADA, PLC or other industrial control software, with a built-in web server and web HMI for direct monitoring and control.Each of the 12 digital inputs accepts either dry or wet contact and can be configured as a 32-bit counter. The 6 isolated open-collector outputs are sink-type, rated at 500 mA per channel. Power can come from IEEE 802.3af Class 1 PoE or from a +12 ~ +48 VDC terminal block.Two built-in 10/100 Base-TX switch ports with LAN bypass allow daisy-chaining without an external switch. Ordering code PET-7250A CR is supplied as the PoE I/O Module with 2-port Ethernet Switch, 12-ch DI, 6-ch DO (RoHS) listed in the shop.ApplicationsBuilding automationFactory automationMachine automationRemote maintenanceRemote diagnosisTesting equipment

The PET-7251 CR is a PoE Ethernet I/O module that brings 16 wet contact digital inputs onto a Modbus network. Each channel can also operate as a 32-bit counter, with a maximum count of 4,294,967,295 and an input frequency of 100 Hz, which suits pulse counting and status monitoring from field contacts.An integrated 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 from PoE (IEEE 802.3af, Class 1) or from a +12 ~ +48 VDC terminal block. The built-in web server and Web HMI, together with ID, password and IP filter access control, support configuration and remote supervision.Optical isolation is rated at 2500 VDC for I/O, with transient overvoltage protection stated at 3750 Vrms. Note that there is no channel-to-channel isolation. The module is DIN-rail mounted and is specified for an operating range of -25 ~ +75 °C.ApplicationsBuilding AutomationFactory AutomationMachine AutomationRemote MaintenanceRemote DiagnosisTesting Equipment

PET-7253 CR is a PoE Ethernet remote I/O module that brings 16 dry contact digital inputs onto a Modbus network. Every input can also run as a 32-bit counter, which suits pulse counting and event tallying on machines and building systems.The built-in 2-port switch with LAN bypass lets you daisy-chain modules along a cable run without a separate switch at each point. Power can come from PoE (IEEE 802.3af, Class 1) or from a +12 to +48 VDC terminal block. Optical isolation gives 3750 Vrms transient overvoltage protection, although the channels are not isolated from each other.An embedded web server and web HMI allow configuration and monitoring from a browser, with access control by ID, password and IP filter. The dual watchdog and I/O pair connection support fault handling in unattended installations.ApplicationsBuilding AutomationFactory AutomationMachine AutomationRemote MaintenanceRemote DiagnosisTesting Equipment

PET-7255 CR is a PoE Ethernet I/O module that combines eight dry/wet contact digital inputs with eight source-type digital outputs. Each input can be configured as a 32-bit counter, and each output channel can drive up to 650 mA per channel at 25°C, making the module suitable for direct switching and counting tasks on a network-attached I/O node.A built-in 2-port 10/100 Base-TX switch with LAN bypass allows units to be daisy-chained along a cable run, reducing the switching hardware needed at each point. The module offers a built-in web server with Web HMI, Modbus TCP and Modbus UDP support, access control by ID, password and IP filter, and dual watchdog protection.Optical isolation of 2500 VDC is provided between I/O and the system, although channels are not isolated from one another. The power-on and safe values of the digital outputs are programmable, so outputs can be set to a defined state at start-up or when communication is lost.ApplicationsBuilding AutomationFactory AutomationMachine AutomationRemote MaintenanceRemote DiagnosisTesting Equipment
