ET-2254P 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 PET-2254P CR is a PoE-powered Ethernet I/O module with 16 programmable channels, each configurable as a digital input or a digital output. Each output channel handles loads of up to 350 mA, so it can drive field devices directly.A built-in two-port 10/100 Base-Tx switch with LAN bypass allows modules to be daisy-chained along the network, which simplifies installation and can lower infrastructure costs. The module provides 3000 VDC I/O isolation and EMS protection against EFT, ESD and surge events. Configuration is carried out through the built-in web server, with password and IP filter access control.Communication options include Modbus TCP and UDP, MQTT publish and subscribe, and SNMP V2c for network management. I/O pair connections let a local DI drive a remote DO in push mode, or pull a remote DI to a local DO, over Ethernet. The module operates from -25 to +75 °C and mounts on a DIN rail.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

ET-2251 CR is an Ethernet I/O module with 16 digital input channels that accept both wet and dry contacts. Each channel can also operate as a 32-bit counter, with a maximum count of 4,294,967,295, so the module suits pulse counting and status monitoring alongside simple switch sensing.The built-in 2-port Ethernet switch with LAN bypass lets you daisy-chain modules along a network line, which reduces the number of switches and cabling needed. Configuration is handled through the built-in web server, and I/O Pair Connection (Push and Pull) allows local DI data to be written to remote DO channels via Modbus TCP.For communication, the module supports Modbus TCP/UDP, MQTT as both publisher and subscriber, and SNMP V2c with optional Trap messages for I/O or restart events. Its EMS protection and 3000 VDC I/O isolation support use in electrically noisy industrial environments.ApplicationsFactory AutomationMachine AutomationBuilding AutomationRemote Diagnosis & MaintenanceTesting Equipment
