Productinformatie "tPET-PD2POR2 PoE Ethernet I/O Module, 2-ch DI and 2-ch PhotoMOS Relay"
The tPET-PD2POR2 CR is a compact Ethernet I/O module that combines two dry-contact digital inputs with two PhotoMOS relay outputs. It is suited to engineers who need remote monitoring and switching over a 10/100 Base-Tx network without the footprint of a larger controller. The module is configured through its built-in web server and supports Modbus TCP, Modbus UDP and MQTT.
Power can come from PoE (IEEE 802.3af, Class 1) over a standard Category 5 cable, or from a +12 to +48 VDC terminal block input, giving a redundant supply arrangement. Two dual-watchdog functions are provided: a CPU watchdog that resets the system if the firmware misbehaves, and a host watchdog that drives outputs to their configured Safe Value if the host controller fails.
Input features include latched DI, 32-bit counters and frequency measurement, with a 3.5 kHz maximum frequency without filter. A DI-to-DO pair connection can be configured over Ethernet, allowing the module to poll local inputs and write to a remote output device in the background.
