Digital Output Module for S7-1500 Series: Model DQ 2xRelay ST, a compact digital output module in the SIMATIC S7-1500 PLC system—provides 2 relay outputs, ideal for small-scale applications requiring electrical isolation and AC/DC load control.
2-Channel Relay Outputs: Each channel uses an electromechanical relay, supporting up to 250 V AC / 30 V DC and a switching current of 2 A—capable of directly driving contactors, small motors, indicator lights, and solenoid valves without additional interface relays.
High Galvanic Isolation: Full electrical isolation between output channels and between the module and backplane bus—effectively suppresses noise and enhances system safety and stability in industrial environments.
AC & DC Load Compatibility: Relay outputs can switch both AC and DC loads, offering high flexibility for diverse field device control applications.
Flexible Parameter Configuration: Configurable safety behavior (e.g., hold last state or set to safe state on power loss), pulse suppression time, and other parameters in TIA Portal—improving system safety and adaptability.
