Summary of PLC Output Current

Summary of PLC Output Current

Recently, I worked on a project using the Mitsubishi Q series PLC, with the output module being the QY81P. I intended to directly drive the Schneider LC1D09BDC contactor with this module, but encountered some issues. Upon checking, I found that the QY81P has an output load current of 0.1A per point and 2A for the … Read more

Can a PLC Bypass Relays to Directly Control Contactors?

Can a PLC Bypass Relays to Directly Control Contactors?

This depends on the specific model of the PLC. PLCs can be categorized into relay output, transistor output, and thyristor output. Relay-type PLCs can directly control contactors, while transistor and thyristor-type PLCs cannot directly control contactors. The maximum output current of relay-type PLCs is 2A, which can drive AC and DC loads. The allowable load … Read more
