6ES7288-3AQ04-0AA0 New Original Siemens S7-200 SMART Plc Programming Controller module

2. Key Selling Points

1. 4-Channel Analog Output – Meets Basic Control Requirements:Provides 4 independent analog output channels for controlling VFD speed, control valve position, actuators, etc., ideal for small closed-loop or open-loop systems.

2. Dual-Mode Output Support – Flexible Application:Each channel可 be configured for ±10 V voltage output or 0/4–20 mA current output, compatible with most industrial field devices.

3. 12-Bit High Resolution – Precise & Stable Output:Delivers 12-bit resolution for current output and 11-bit + sign for voltage, ensuring accurate and smooth analog signal generation.

4. Optical Isolation – Strong Noise Immunity:Features galvanic isolation between CPU and field side, preventing interference from affecting the controller and enhancing system reliability.

5. Open-Circuit Detection & Safe Output on Fault:Supports open-circuit detection (for current outputs) and allows setting of safe output values (e.g., 0 mA, 0 V, or hold last value) during communication failure or module error.
