TDI340 S0 pulse counter with MODBUS RTU interface Overview TDI340 is а S0 pulse counter with the MODBUS RTU interface. It has 4 isolated digital inputs, complying with the S0 standard 62053-31. The S0 pulse counter works in polling or edge modes. In edge mode, it can be set up to count on rising, falling and both edges. The device is dedicated to the S0 pulse counter but it also provides simultaneous readings for the state of the digital inputs - OPEN/CLOSE. Independent delays for Low-To-High and High-To-Low transitions can be applied. The delays are from 0 to 656 seconds in 10mS step and work if the counter for the corresponding digital input is in polling mode. Applications • Remote monitoring of electricity meters; • Remote data acquisition; • Industrial process control; • Remote monitoring of gas meters; • Remote monitoring of water meters; • Energy management; • Monitoring of devices with S0 outputs; • Process monitoring. Basic features • RS-485 interface carrying up to 63 nods; • Non-volatile memory for counters storage; • Built-in 120 ohms termination resistor; • Wide supply voltage range, starting from 5VDC; • Galvanically isolated inputs; • Firmware update via the interface.
