High-speed outputs
High-speed outputs can be set as either a sink line or source line.
*1 The delay due to the turning OFF of optical isolators depends on which output is connected to the load.
With a 240
Ω
load, the maximum delay will be 200
μ
s.
For a sink type device, connect an external load between 'High-speed output 0' to 'High-speed output 3' of a breakout cable
and the positive side (26.4 VDC or less).
When 'High-speed output 0' to 'High-speed output 3' are turned ON, the outputs are pulled down to 3 VDC or less, then a
current flows to the external load.
When 'High-speed output 0' to 'High-speed output 3' are turned OFF, a current does not flow to the external load.
For a source type device, connect an external load between 'High-speed output 0' to 'High-speed output 3' of a breakout cable
and the negative side (0 VDC).
For a connection to which a 24 VDC power supply is connected, when 'High-speed output 0' to 'High-speed output 3' are
turned ON, the voltage of the outputs are pulled up to 21 VDC or more, then a current flows to the external load.
When 'High-speed output 0' to 'High-speed output 3' are turned OFF, a current does not flow to the external load.

Each line is rated at a maximum 50 mA and protected against over-current, short circuits, and transients from switching inductive loads.
A protection diode is required for a high inductive load.
