PET-2252 PoE Ethernet I/O Module, 16-ch Universal DIO

The ET-2252 CR is a DIN-rail Ethernet I/O module with 16 universal channels, each configurable as a digital input or digital output. Each output channel can switch a load of up to 450 mA, and the module can be polled over Modbus TCP/UDP, or publish and subscribe over MQTT, or report to SNMP V2c management systems.A built-in 2-port Ethernet switch with LAN bypass allows modules to be daisy-chained along a line, which reduces the number of network drops and switches needed in a panel or machine. Peer-to-peer I/O pair connections let local inputs drive remote outputs, or remote inputs drive local outputs, over Ethernet without a host controller in the loop.Electrical isolation is rated at 3000 VDC for the I/O and 1500 VDC for Ethernet, and the module includes EMS protection against EFT, ESD and surge events. Dual power inputs from +10 to +48 VDC support redundant supply designs, and the configurable power-on and safe values define how outputs behave at start-up and during communication loss.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

PET-2251-32 is an Ethernet I/O module that gathers 32 Wet/Dry digital inputs, and each channel can also be used as a 32-bit counter with a maximum count of 4,294,967,295. Its built-in 2-port switch with LAN bypass lets you chain devices along the network, which reduces cabling and switch hardware in distributed installations.For control tasks, the module supports I/O Pair Connection, so local DI status can be pushed to remote DO channels over Ethernet using Modbus TCP. It also works as an MQTT publisher and subscriber, publishing I/O status as topics and reconnecting to the broker automatically after a dropout. SNMP V2c allows module and I/O data to be read by network management software, and Trap messages can alert administrators when inputs change or the unit restarts.Electrical robustness is covered by 3000 V DC I/O isolation and EMS protection against EFT, ESD and surge events. The module is powered over PoE (IEEE 802.3af, Class 2) or from a +10 ~ +48 VDC terminal block, and is rated for -25 ~ +75 °C operation on a DIN rail.ApplicationsFactory AutomationMachine AutomationBuilding AutomationRemote Diagnosis & MaintenanceTesting Equipment

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
