Description
The Siemens SIMATIC S7-1200 SM 1222, DQ 16x relay 2 A provides 16 digital relay outputs for switching externally supplied AC or DC loads. The relay contacts support 5–30 V DC and 5–250 V AC, with a maximum switching current of 2 A for resistive and inductive loads. The module supports a maximum lamp load of 30 W with DC and 200 W with AC, making it suitable for a broad range of industrial switching applications. Each relay output is independently operated, while the relay coils are supplied by 24 V DC through the module’s load-voltage connection. Siemens specifies a maximum output delay of 10 ms for both 0-to-1 and 1-to-0 transitions with resistive loads.
The module provides four groups of relay outputs, with electrical separation between relay groups and 1,500 V AC isolation between the output circuits and the backplane bus. It supports shielded cables up to 500 m and unshielded cables up to 150 m, and includes diagnostic alarms and LED indication for monitoring output status. The relay contacts are rated for up to 10 million mechanical operating cycles and 100,000 cycles at rated load voltage, providing durability for repeated switching operations. With its 16-channel configuration, the SM 1222 is well suited to machine automation, process equipment, control panels, valve control, contactor switching, lighting control, and other industrial applications requiring flexible AC/DC relay outputs.
