Toote teave "tET-A4 Tiny Ethernet I/O Module, 4-ch Digital Output (PNP Source)"
The tET-A4 CR is a compact Ethernet I/O module with four digital outputs, configured as PNP (source) open-collector channels. It lets an engineer switch remote loads from a Modbus TCP, Modbus UDP or MQTT host over a 10/100 Base-Tx network, which suits PLC, HMI and SCADA integration.
Its small footprint allows it to be fitted on a DIN rail or embedded directly within a machine. The module is supplied with a web server for configuration, and it can be updated with new firmware over Ethernet. Each output has a power-on value and a safe value, and the module provides both a CPU watchdog and a host watchdog to protect the outputs if the controller fails.
Key points for specification:
- Four PNP (source) open-collector outputs rated at 650 mA per channel, with a load voltage of +10 to +40 VDC
- Operates from +12 to +48 VDC supplied through a removable terminal block
- Photo-isolated outputs with 3750 Vrms isolation
Applications
- Factory automation
- Building automation
- Home automation
- Remote maintenance
