PET-2254P PoE Ethernet I/O Module, 16-ch Universal DIO with 2-port Switch

The PET-2254 CR is a PoE-powered Ethernet I/O module with 16 universal digital channels. Each channel can be configured as a digital input or a digital output, and each output can drive a load of up to 100 mA. It suits engineers who need flexible remote discrete I/O with network monitoring and control.An integrated 2-port 10/100 Base-Tx switch with LAN bypass lets modules be daisy-chained along a cable run, which simplifies installation and reduces switch infrastructure. The module supports Modbus TCP and Modbus UDP, publishes and subscribes to MQTT topics, and reports I/O status and traps over SNMP V2c. I/O pair connections allow local inputs to be pushed to remote outputs, or remote inputs to be pulled to local outputs, over Ethernet.Built-in EMS protection and 3000 VDC I/O isolation support operation in electrically noisy industrial environments. Power-on and safe values for the outputs are programmable, and the module can be powered from PoE (IEEE 802.3af, Class 1) or from a +10 ~ +48 VDC terminal block.ApplicationsFactory AutomationMachine AutomationBuilding AutomationRemote Diagnosis & MaintenanceTesting Equipment

The ET-2254 CR is an Ethernet I/O module offering 16 universal channels, each configurable as a digital input or a digital output. Its digital outputs are open-collector sink types rated at 100 mA per channel, with a load voltage of +5 ~ +30 VDC, while the digital inputs are source type. It suits engineers who need flexible I/O on an Ethernet network without a separate switch.A built-in 2-port 10/100 Base-Tx switch with LAN bypass allows modules to be daisy-chained, which reduces cabling and network infrastructure. The module can also be configured through its web server, and access is protected by password and IP filter. Dual-watchdog functionality, along with programmable power-on and safe values for the digital outputs, helps keep the process in a defined state.I/O Pair Connection lets local digital inputs be written to remote digital outputs in Push mode, or remote inputs be pulled to local outputs, over Ethernet using Modbus TCP. For higher-level systems, the module acts as an MQTT publisher and subscriber and supports SNMP V2c monitoring with optional Trap messages on I/O changes or restarts. Isolation is rated at 3000 VDC for I/O and 1500 VDC for Ethernet.ApplicationsFactory AutomationMachine AutomationBuilding AutomationRemote Diagnosis & MaintenanceTesting Equipment

The ET-2254P provides 16 programmable universal channels, each configurable as a digital input or a digital output. Each output can drive a load of up to 350 mA. A built-in two-port 10/100 Base-Tx switch with LAN bypass supports daisy-chain topologies, which simplifies installation.Communication options include Modbus TCP/UDP, MQTT and SNMP V2c, and a built-in web server handles configuration. I/O pair connection lets local digital inputs drive remote digital outputs in Push mode, or pull remote inputs to local outputs, over Ethernet. Dual-watchdog support and programmable power-on and safe values for the outputs help engineers define how the system behaves on start-up and fault conditions.With 3000 VDC I/O isolation and EMS protection against EFT, ESD and surge, the module is suited to electrically noisy industrial environments. It mounts on a DIN rail, is powered from +10 ~ +30 VDC and is rated for operation from -25 ~ +75 °C.ApplicationsFactory AutomationMachine AutomationBuilding AutomationRemote Diagnosis & MaintenanceTesting Equipment

The PET-2251 CR is a PoE Ethernet I/O module that brings 16 digital input channels onto an IP network. Each channel accepts dry or wet contact signals and can operate as a 32-bit counter, which suits pulse counting and status monitoring on machines and building services.A built-in 2-port switch with LAN bypass lets you daisy-chain modules along a single cable run, reducing switch infrastructure and simplifying installation. The module is isolated at 3000 VDC on the I/O side and provides EMS protection (EFT, ESD and surge) for electrically noisy plants.Communication options include Modbus TCP and Modbus UDP, MQTT publish and subscribe, and SNMP V2c with optional traps for status changes or restarts. I/O pair connections let local DI states be pushed to remote DO channels over Ethernet, and dual watchdogs help maintain control of the system.ApplicationsFactory automationMachine automationBuilding automationRemote diagnosis and maintenanceTesting equipment
