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.

24 VAC/VDC operating only with safety isolating transformer according EN 61558-2-6

Modbus TCP

Note:
Ethernet cable shall be Cat 5e or Cat 6 cable. Wire colour indication is for T568B pinout.

24 VAC/VDC operating only with safety isolating transformer according EN 61558-2-6.
