Description
Siemens 6ES7 235-0KD22-0XA0 Analog Input/Output (EM 235). Specifically, it is an integratedAnalog Input/Output (EM 235) module. The EM 235 is famous for itsDIP switch bank located on the bottom of the unit. Output Channels 1 Analog Output. Input Channels 4 Analog Inputs. The Siemens 6ES7 235-0KD22-0XA0 is a legacy analog expansion module from the SIMATIC S7-22x (S7-200) PLC family. Specifically, it is an integrated Analog Input/Output (EM 235) module. Because the S7-200 series is now considered a legacy product (replaced by the S7-1200), these modules are primarily used for maintaining existing industrial machinery rather than new installations. 🛠️ Technical Specifications This module is versatile because it handles both incoming sensor signals and outgoing control signals in a single unit. Feature Specification Input Channels 4 Analog Inputs Output Channels 1 Analog Output Input Voltage Ranges ±50mV, ±100mV, ±250mV, ±500mV, ±1V, ±2.5V, ±5V, ±10V Input Current Ranges 0 to 20 mA Output Ranges ±10V (Voltage) or 0 to 20 mA (Current) Resolution 12-bit A/D and D/A conversion Isolation None (common ground between inputs and logic) ⚙️ Configuration & DIP Switches The EM 235 is famous for its DIP switch bank located on the bottom of the unit. These must be physically toggled to match your signal type (e.g., switching from a 0–10V pressure sensor to a 4–20mA flow meter). Gain Adjustment: There is a "Gain" potentiometer on the front to fine-tune the signal. Offset Adjustment: There is an "Offset" potentiometer to calibrate the zero-point of your analog signals.
