16-Point Relay Digital Output (DQ):Provides 16 digital output channels with relay contact outputs, allowing independent control of AC or DC loads—ideal for diverse switching applications.
High Load Driving Capability:Each relay contact supports up to 250V AC / 30V DC and a maximum current of 2A, capable of directly driving contactors, solenoid valves, indicator lamps, and small motors without additional interface relays.
Flexible Wiring Design:Features removable screw-type terminal connectors for secure and reliable wiring, enabling easy installation, maintenance, and quick module replacement.
Plug-and-Play with Auto-Recognition:Simply install the module to the right side of the S7-200 SMART CPU; it is automatically detected upon power-up—no manual configuration required, streamlining commissioning.
Electrical Isolation:The output channels are electrically isolated from the backplane bus, effectively suppressing external noise and enhancing system immunity and operational reliability.
Supports Multiple Load Types:Capable of switching both AC loads (e.g., 220V AC contactors) and DC loads (e.g., 24V DC solenoids), offering broad application flexibility.
