The TM3AQ4 (screw terminal block) / TM3AQ4G (spring terminal block) expansion module feature 4 analog output channels with 12-bit resolution.
The channel output types are:
o0...10 V
o-10...+10 V
o0...20 mA
o4...20 mA
For further hardware information, refer to TM3AQ4 / TM3AQ4G.
NOTE: If you have physically wired the analog channel for a voltage signal and you configure the channel for a current signal in EcoStruxure Machine Expert, you may damage the analog circuit.

NOTICE |
|
INOPERABLE EQUIPMENT |
|
Verify that the physical wiring of the analog circuit is compatible with the software configuration for the analog channel. |
|
Failure to follow these instructions can result in equipment damage. |
For each output, you can define:

1 The 12-bit data (0 to 4095) processed in the analog I/O module can be linear-converted to a value between -32768 and 32767.
Variables can be defined and named in the I/O Mapping tab. Additional information such as topological addressing is also provided in this tab.
