PET-2242 PoE I/O Module with 2-port Switch, 16-ch Digital Output (Sink)

The ET-2242 CR is an Ethernet I/O module offering 16 open-collector digital outputs in sink configuration, with each channel rated for a 650 mA load. It suits engineers who need to switch a group of loads over Ethernet without a separate network device, as the built-in 2-port switch lets modules be daisy-chained along a line.Beyond switching, the module can be configured to hold a programmable power-on value and safe value for its outputs. Its I/O pair connection function links local DO channels to DI channels on a remote module over Ethernet, with remote DI data written to local outputs in Pull mode via Modbus TCP. Dual-watchdog support, a built-in web server and password and IP filter access control add to its configuration and operational options.For electrically demanding sites, the ET-2242 CR provides 3000 VDC I/O isolation and EMS (EFT/ESD/Surge) protection. Its MQTT publisher and subscriber capability and SNMP V2c support allow I/O status to be reported to brokers and network management software.ApplicationsFactory AutomationMachine AutomationBuilding AutomationRemote Diagnosis & MaintenanceTesting Equipment

PET-2242U-32 provides 32 digital output channels with sink/source operation, each channel rated for a 300 mA load across +3.5 ~ +80 V. Photocoupler isolation and short-circuit protection on every channel make it suitable for switching field loads from a networked I/O point.A built-in two-port Ethernet switch with LAN bypass supports daisy-chain wiring, reducing cabling and the need for separate switch hardware. The module can be powered over PoE (IEEE 802.3af, Class 1) or from a +10 ~ +48 VDC terminal block, and includes EMS protection and 3000 VDC I/O isolation for electrically noisy plants.Communication is available over Modbus TCP and UDP, MQTT publish/subscribe and SNMP V2c, with a built-in web server for configuration. Programmable power-on and safe values let engineers define output states, and I/O Pair Connection allows remote DI data to be written to local DO channels in Pull mode.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
