PLC Board Hima F3417A Relay Amplifier Module Best Quality

Hima F3417A PLC Module with Quality Warranty The HIMA F3417A is a 4-fold fail-safe relay amplifier PLC board. It is used to amplify the output signal of a PLC or other control system to drive a relay or other output device. The F3417A has four independent channels, each of which can be configured to operate in one of two modes: fail-safe or non-fail-safe. In fail-safe mode, the output of the channel is always in the safe state, even if the input signal is lost. This is accomplished by using a redundant power supply and a watchdog timer. If the input signal is lost or the power supply fails, the watchdog timer will eventually expire and the output of the channel will be switched to the safe state. In non-fail-safe mode, the output of the channel follows the input signal. This mode is typically used for applications where the output device does not need to be in a safe state in the event of a power failure or loss of the input signal. The F3417A is a rugged and reliable board that is
