The BSSRT solid state relay is a zero-cross operating electronic module designed to switch single-phase AC power loads. Thanks to its higher switching frequency and practically complete absence of electromagnetic interference, the SSR module is a non-contact and convenient substitute of power contact relays. The life and reliability of the SSR module, compared to these of the contact relays, are much higher because there are no moving parts, noise, shocks, and vibration during the operation. The BSSRT electronic relays can switch active loads up to 200 Arms and inductive loads up to 95 Arms at power voltage up to 400 VAC. The control input is optically isolated from the output and accepts AC or DC voltage signals. An operating LED indicates ON/OFF device status.
