SSM2 Harmony Solid-State Relays

Schneider Electric SSM2 Harmony Solid-State Relays (SSRs) feature a dual-channel, single-phase relay configuration with a 6A rating in a compact modular DIN-rail housing. These devices handle two AC load channels and integrate a heat sink, screw terminals, and green LED input-status indicators. The solid-state construction enables silent operation without moving contacts. Schneider Electric SSM2 Harmony Solid-State Relays are available in two options. The SSM2A16BD uses zero-voltage switching for resistive loads, while the SSM2A16BDR provides random-voltage switching for inductive loads. Both types offer robust performance in harsh environments and resist shock and vibration.
