PET-7255 PoE Ethernet I/O Module with 2-Port Switch, 8-ch DI/DO

The ET-7255 CR is an Ethernet I/O module that combines 8 dry/wet contact digital inputs, each usable as a 32-bit counter, with 8 source-type digital outputs. Its built-in 2-port switch with LAN bypass lets you daisy-chain modules along a line without a separate switch, and the module is controlled over Modbus TCP or Modbus UDP.Each output channel can drive a load of 650 mA, and the power-on and safe values of the outputs are programmable, so the module can be configured to reach a defined state on start-up or after a communication fault. Optical isolation of 2500 VDC is provided on the I/O, with 1500 VDC on the Ethernet side. The source notes that channels are not isolated from each other.Configuration and monitoring are handled through the built-in web server and web HMI, with ID, password and IP filter access control. The module is rated from -25 ~ +75 °C and mounts on a DIN rail.ApplicationsBuilding automationFactory automationMachine automationRemote maintenanceRemote diagnosisTesting equipment

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

The PET-7252 CR is a PoE Ethernet I/O module for remote monitoring and control of discrete signals. Its eight wet-contact digital inputs can each operate as a 32-bit counter, and its eight source-type digital outputs each switch up to 650 mA at 25°C, making it suited to driving field loads directly from the module.Each output channel has a programmable power-on value and safe value, so the outputs can be set to a defined state at start-up or during a communication fault. Optical isolation of 2500 VDC is provided between I/O and the module, although the channels are not isolated from one another. The source states the module can be used where hazardous voltages are present.Networking is handled by a 2-port 10/100 Base-TX switch with LAN bypass, which supports daisy-chain topologies. The module can be powered over PoE (IEEE 802.3af, Class 1) or from a +12 ~ +48 VDC terminal block, and it is designed for DIN-rail mounting.ApplicationsBuilding AutomationFactory AutomationMachine AutomationRemote MaintenanceRemote DiagnosisTesting Equipment
