PET-7051 PoE I/O Module, 16-ch Wet Contact Digital Input

The PET-7050 CR is a networked I/O module from the ET-7000 family that brings 12 digital inputs and 6 digital outputs onto an Ethernet network. Each input channel can also operate as a 32-bit counter, which suits pulse counting and status monitoring tasks. The module is controlled remotely over Modbus TCP or Modbus UDP, so it can be integrated with HMI, SCADA, PLC and other industrial control software.Power can be delivered over the same copper Ethernet cable under IEEE 802.3af (Class 1) Power-over-Ethernet, which removes the need for a separate supply at the point of installation. Alternatively, the module can be powered from a terminal block at +12 ~ +48 VDC. Built-in web-based monitoring and control, together with dual watchdog functions and I/O pair connection, support straightforward commissioning and supervision.Suited to building, factory and machine automation, remote maintenance and diagnosis, and test equipment.ApplicationsBuilding AutomationFactory AutomationMachine AutomationRemote MaintenanceRemote DiagnosisTesting Equipment

The PET-7052 CR is a PoE-powered Ethernet I/O module for engineers who need eight digital inputs and eight digital outputs on a Modbus network. Each input channel accepts wet contact signals and can count pulses with a 32-bit counter, while each output channel is a source-type driver rated for 650 mA per channel at 25°C.Output behaviour can be configured for start-up and fault conditions, with a programmable power-on value and safe value for each digital output. A built-in web server with Web HMI, access control by ID, password and IP filter, and dual watchdogs (module and communication) help with commissioning and supervision.Powered over Ethernet (IEEE 802.3af, Class 1) or from a 12 ~ 48 VDC terminal blockWet contact inputs with counter capability up to 500 HzSource-type outputs with short-circuit protectionThe module provides 2500 VDC optical isolation for transient overvoltage protection of the I/O, but does not offer channel-to-channel isolation. The manufacturer states it can be used where hazardous voltages are present.ApplicationsBuilding automationFactory automationMachine automationRemote maintenanceRemote diagnosisTesting equipment

PET-7053 CR is a PoE Ethernet I/O module that brings 16 dry contact digital inputs onto a Modbus network. Every channel can also be configured as a 32-bit counter, making it suited to pulse counting and status monitoring tasks where a PLC or SCADA system needs remote visibility of field contacts.The module can be powered over Ethernet to IEEE 802.3af or from a +12 ~ +48 VDC terminal block, and it includes a built-in web server with web HMI for configuration and monitoring. Dual watchdogs (module and communication, programmable) help the module recover from faults. Access is protected by ID, password and IP filter.Optical isolation is provided between I/O and the system at 2500 VDC, with transient overvoltage protection rated at 3750 Vrms. Channels are not isolated from each other, so the module should be considered for applications where the inputs share a common reference. Its voltage rating allows use where hazardous voltages are present.ApplicationsBuilding automationFactory automationMachine automationRemote maintenanceRemote diagnosisTesting equipment

PET-7042 CR is a PoE-powered Ethernet I/O module that switches up to 16 sink-type digital outputs over Modbus TCP or Modbus UDP. It suits engineers who need remote switching of loads or indicators on an Ethernet network without a separate power supply for the module, as it can be powered from PoE (IEEE 802.3af, Class 1) or from a +12 ~ +48 VDC terminal block.Each output is an isolated open-collector channel rated at 100 mA per channel at 25°C, with a load voltage of +5 ~ +30 VDC. Overload protection and short-circuit protection are included. The power-on value and safe value of every channel are programmable, so outputs can be set to a defined state at start-up or on communication loss. The I/O is isolated at 2500 VDC, but the channels are not isolated from each other. For inductive loads, the outputs can drive an RM series relay module directly.The module has a built-in web server with Web HMI, access control by ID, password and IP filter, dual watchdog and I/O pair connection. It mounts on a DIN rail and is specified for an operating temperature of -25 ~ +75 °C. The unit is RoHS compliant and carries CE, UKCA, FCC and WEEE marks.ApplicationsBuilding AutomationFactory AutomationMachine AutomationRemote MaintenanceRemote DiagnosisTesting Equipment
