INPUT/OUTPUT controls
• When using a solid-state output with the maximum switching current rating over 1A , there is a possibility of causing
External Input Errors due to the delay of rise /fall time of output signal. Consider this when selecting the solid-state
output.
• When using a contact output, consider chattering and the minimum switching current.
• When connecting an inductive load or an electrical device that tends to generate noise to the output, connect a diode
in parallel with the load. Connect the cathode side of the diode to the positive side of the power supply.
