The TDI340 is an S0 pulse counter equipped with a MODBUS RTU interface and features 4 isolated digital inputs, all complying with the S0 standard 62053-31. This counter operates in either polling or edge modes, with the edge mode capable of counting on rising, falling, or both edges.
In essence, the device incorporates 4 independent counters, with their information securely stored in non-volatile memory to prevent data loss. Beyond raw impulse data, the device offers registers for true physical values, making it ideal for recording energy, water, gas, and more directly.
The device is designed specifically for pulse counting and provides simultaneous readings of the digital inputs' state (OPEN/CLOSE).
Furthermore, it supports independent delays for Low-To-High and High-To-Low transitions ranging from 0 to 656 seconds in 10ms increments, particularly useful for additional digital pulse filtering.
With a wide supply voltage range spanning from 5 to 30 volts, it is well-suited for various industrial applications.
This counter can be used with the Energy monitoring module TCW260 and third-party MODBUS RTU master devices.
