Terminal	Description
L24	Power supply 24 VAC/VDC.
M*	Neutral for power supply 24 VAC/VDC and signals.
XV	Output signal 0(2)-10 VDC, max. 8 mA or min. load resistance 1.25 kΩ.
M (0V)*	Neutral for signal.
Y	Input signal 0(2)-10 VDC, 47 kΩ or 0(4)-20 mA, 500 Ω (selectable by jumper

USB Only for IMI use.
Serial Debug Only for IMI use.
All M terminals are internally connected.

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.
