Built-in Watchdog, Input Protection circuitry | ICP DAS USA 8KE4

Built-in Watchdog

The built-in watchdog circuit will reset the CPU module if a failure occurs in either the hardware or software. If the application program does not refresh the watchdog timer within 0.8 sec, the watchdog circuit will initiate a reset of the CPU.

Input Protection circuitry

The protection circuitry on both the network and power supply protects the system from external signals such as main spikes and ambient electrical noise. In addition, the central processing module is isolated from external signals in three ways. This is achieved through I/O isolation of 3KV, power isolation to 3KV and network isolation to 2KV

High performance integrated power supply

The built-in isolated 20W power supply is rated to perform linearly up to full loading.

Ventilated housing design to work between -25 ~+75℃

The 8430/8830/8KE4/8KE8 is housed in a plastic base box with a column-like ventilator, that can help to cool the work environment inside the box and allow the 8430/8830/8KE4/8KE8 to operator between -25℃and +75℃.
