The PET-7017-10 is a PoE-powered Ethernet analog input module for engineers who need voltage or current measurement on a networked I/O node. Its inputs can be set as 10 differential or 20 single-ended channels in software, and each channel can be given its own range, so one module can serve mixed sensor types on the same network.Each channel offers a choice of voltage ranges from ±150 mV to ±10 V and current ranges of ±20 mA, 0 ~ 20 mA and 4 ~ 20 mA, selected with jumpers. Resolution is 16-bit, and the module has two sampling modes: normal mode at 10 Hz total and fast mode at 50 Hz total. Open wire detection is available for 4 ~ 20 mA inputs, and differential channels are rated for 240 Vrms overvoltage protection.Configuration and monitoring are handled through a built-in web server with Web HMI, and the module supports Modbus TCP and Modbus UDP. Access is controlled by ID, password and IP filter. The unit is powered either from PoE (IEEE 802.3af, Class 1) or from a +12 ~ +48 VDC terminal block, and it mounts on a DIN rail.ApplicationsBuilding automationFactory automationMachine automationRemote maintenanceRemote diagnosisTesting equipment
