Hi, The I/O Overload trip indicates that the total current drawn from 24 V user supply or from the digital output has exceeded the limit. A trip is initiated if one or more of the following conditions: • Maximum output current from one digital output is 100 mA. • The combined maximum output current from outputs 1 and 2 is 100 mA • The combined maximum output current from output 3 and +24 V output is 100 mA Recommended actions: • Check total loads on digital outputs • Check control wiring is correct • Check output wiring is undamaged
