New Product: tPET-A4、tET-A4
Tiny Ethernet I/O Module (with PoE) with 4-ch Open Collector DO (Source, PNP)
Introduction:
The t(P)ET-A4 is an IP-based Tiny Ethernet I/O monitoring and control module. The module can be remotely controlled through a 10/100 M Ethernet network by using Modbus TCP/UDP protocol. Modbus has become a de facto standard communications protocol in industry, and is now the most commonly available means of connecting industrial electronic devices. This makes the t(P)ET-A4 perfect for integration into the HMI, SCADA, PLC and other software systems.
The tET-A4 and tPET-A4 contain 4 channels of open collector outputs (Source, PNP). The module can be used to create I/O pair-connect through the Ethernet. Once the configuration is completed, the t(P)ET series module polls the status of the local DI channels and then write to a remote DO device continuously in the background with the Modbus/TCP protocol.
"Built-in Web server"
The t(P)ET series features a powerful 32-bit MCU to enable efficient handling of network traffic. It also has a built-in web server that provides an intuitive web management interface to allow users to modify the settings of the module including DHCP/Static IP, gateway/mask.
"Built-in Dual Watchdog"
The t(P)ET series module provides dual watchdog: CPU watchdog and host watchdog. The CPU watchdog which automatically resets the CPU if the built-in firmware is operating abnormally, while the host watchdog set the digital output with predefined safe-value when there is no communication between the module and the host (PC or PLC) for a period of time (watchdog timeout). The dual watchdog is an important feature that ensures the module operates continuously, even in harsh environments.
"Low Power Consumption"
The tPET series module offers true IEEE 802.3af-compliant (classification, Class 1) Power over Ethernet (PoE) using a standard category 5 Ethernet cable to receive power from a PoE switch such as the NS-205PSE. If there is no PoE switch on site, the module can also accept power input from a terminal block. The t(P)ET series is designed for ultra-low power consumption, reducing hidden costs from increasing fuel and electricity prices, especially when you have a huge amount of devices installed. Reducing the amount of electricity consumed by choosing t(P)ET series can have a positive contribution to environment.
"PWM (Pulse Width Modulation)"
The DOs on the t(P)ET series provide PWM (pulse generation) function. Users can set different frequency and duty cycle for each digital output channel. In addition, the two DO channels can work independently or simultaneously. The t(P)ET series product reduces the complexity of the control system and enhances the timing accuracy.
