Specifications
Transistor Output Unit C200H-OD21A
(Load Circuit Protection Provided)
Circuit Configuration
Note 1. When the short-circuit/overload protection is activated, all 16 outputs are switched OFF and the ALARM
output becomes active (low level). It is possible to determine the cause of the alarm by connecting either
a DC Input Unit to the alarm output or an alarm output LED indicator.
2. When alarm output turns ON, remove the cause of the overload, turn OFF the external power supply (for
about 1 s), and confirm that the error has been cleared before turning ON power again and restoring
output.
As indicated in the following terminal connections diagram, it is recommended that a relay or switch
used solely to turn ON and OFF the Unit's external power supply be connected immediately in front of B9
(+V). In this case, use a relay or switch with a contact capacity that is greater than the current consump-
tion of the external power supply for the Unit (35mA) + the load current.
