The TDI340 is an S0 pulse counter featuring a Modbus RTU interface and four isolated digital inputs that comply with the S0 standard 62053-31.It offers flexible counting in polling or edge modes, with the latter supporting rising, falling, or both edges. The device essentially functions as four independent counters, storing data in non-volatile memory to prevent loss. Beyond raw pulse counts, it provides registers for calculated physical values, enabling direct recording of metrics like energy, water, or gas. Additionally, it offers simultaneous readings of digital input states (OPEN/CLOSE).
For enhanced pulse filtering, the TDI340 allows independent, user-configurable delays (0 to 656 seconds in 10ms steps) for Low-To-High and High-To-Low transitions when in polling mode. Its broad supply voltage range of 5 to 30 volts makes it highly adaptable for diverse industrial applications.
