Transistor Output Modules
As with all other output configurations the physical outputs of transistor output modules are
isolated by opto-coupler.
Response of the transistor in either direction is only 1 ms at 24 V DC, 200 mA. The exact cur
-
rent handling capacity of each output is specified in the relevant hardware manual.
For the MELSEC System Q transistor output modules are available in sink and source
configuration.
