Analog I/O

Analog Outputs (AO1, AO2, AO3, AO4)
Notes:
1. All analog outputs can be operated in either voltage mode (0 to 5V) or ratiometric mode
(programmed as a percentage of an input reference voltage, range 0 to 15V).
2. The programming of the mode of operation and the default (on power up) voltage or ratio
is performed in the "Configure Analog Outputs" task of the ECM Configuration Tool [on
CD].
3. For example: If analog output AO1 is to be operated in voltage mode, parameter AO1V
would be sent to the module (in an RPDO) with the desired voltage value.
4. For example: If analog output AO1 is to be operated in ratiometric mode, AO1 would be
programmable as a percentage of whatever input reference voltage VRF1 was (via the
parameter AO1%). Both AO1 and VRF1 use GNDa1 as ground. AO1% is sent in an
RPDO to the module.
5. The below table gives details of the analog outputs, their voltage references, and their
grounds.
6. All voltage outputs are 12 bit, all voltage inputs (references) are 16 bit.
7. All analog outputs and voltage references share a common ground.
8. Max current 10mA/channel. Output Impedance 1Ω.
9. C/T# below means Connector/Terminal Number. The left (gray) terminal is "L", the
right (black) is "R". See Figure 1 below for connector and terminal numbering.
