Standard
24 VAC/VDC operating only with safety isolating transformer according EN 61558-2-6
Modbus RTU
Note:
- A, B and M terminals are NOT isolated from all other terminals.
- GND (M – 0V) is common to power supply, analog signals and RS 485.
- In case of AC power supply, L24 and M should be connected to the same phase for each TA-Smart.
- GND (0V) of RS 485 should be connected to 0 VAC/VDC on the controller side.
- GND (0V) of analog input/output should be connected to 0 VAC/VDC on the controller side.
