Pulse input equivalent circuit:
Two states of input signal (High and Low) are produced by opening input from, or
closing to the COM terminal. Opening/closing of the input can be realized either by using
contact devices (relay, switch) or non-contact devices (transistor, open-collector TTL).
9-3-2. AO channel select
This menu item specifies an AO channel that will be configured using [AO OUTPUT
MODE], [AO ZERO OUTPUT WEIGHT], [AO FULL SCALE VALUE], [AO
OUTPUT COMPENSATION], [AO LOWER LIMIT], and [AO UPPER LIMIT]
parameters.
* Parameters for the three analog output channels (ch1, ch2, ch3) can be configured
independently to each other. Select a correct channel before modifying parameters.
Operation
9-3-3. AO output mode
This menu item select, for each channel, the type of data sent out from the AO channel.
Operation
- External devices must be capable of sinking more than 15mA (Ic).
- Leak current in the external device should be less than 100
μ A.
