The Siemens 6ES7322-1HH01-0AA0 is a SIMATIC S7-300 SM 322 digital output module with 16 isolated relay outputs. The potential-free contacts allow switching of AC or DC load circuits with galvanic separation from the control side, suited to mixed-voltage panels and loads that should not share a common supply with the PLC.
A 1x 20-pin front connector is required and sold separately.
