4.4 I/O Combined Module Specifications
The I/O combined module equips the overload protection function and the overheat protection function.
*1 This function is for protecting the internal circuit of the module, not for protecting external devices.
Also, leaving the failure too long may rise the internal temperature of the module, resulting in deterioration of output
elements and/or discoloration of a case and printed circuit board. When the failure occurs, turn off the corresponding
outputs immediately to remove the causes.
*2 This operation limits overcurrent to a constant value and keeps outputting it.
Function Description
Overload protection function
*1
• If the output side detects overcurrent, it limits output current by the current limiter operation
*2
• For the overcurrent detection value and the limited current, refer to "Overload protection function" on the
module specifications.
• When the load current becomes lower than the overcurrent detection value, the module returns to normal
operation.
Overheat protection function
*1
• If overcurrent keeps flowing due to overload on the output side, heat is generated inside the module. When
high heat is detected inside the module, the output is turned off.
• The number of output points that the overheat protection function simultaneously operates differs depending
on the module. For the number, refer to "Overheat protection function" on the module specifications.
• After heat goes down, the module returns to normal operation.
