6ES7234-4HE32-0XB0 Siemens S7-1200 Analog I/O Module

6ES7234-4HE32-0XB0 SIMATIC S7-1200 SM 1234 Analog I/O Module

• Brand and Model: Siemens 6ES7234-4HE32-0XB0, part of the SIMATIC S7-1200 SM 1234 series. This analog signal module offers 4 inputs and 2 outputs in a 45 mm wide housing.
• Power Supply Requirements: Operates on a 24 V DC rated supply with 60 mA typical current consumption. The module draws an additional 80 mA from the 5 V DC backplane bus. Typical power loss stays at 2 W.
• Analog Input Specifications: Four differential inputs accept voltage or current signals. Voltage ranges include ±10V, ±5V, and ±2.5V with ≥9 MOhm input resistance. Current ranges cover 0-20 mA and 4-20 mA with 280 Ohm resistance.
• Analog Input Resolution: Delivers 12-bit resolution plus a sign bit for voltage signals. The maximum cycle time for all channels reaches 625 µs. You can parameterize integration time and smoothing levels (none, low, medium, high).
• Analog Output Features: Two outputs support voltage or current signals. Voltage output range spans -10V to +10V with a minimum load impedance of 1,000 Ohms. Current outputs cover 0-20 mA and 4-20 mA with a maximum load of 600 Ohms.
• Analog Output Resolution: Provides 14-bit resolution for voltage outputs. Current outputs achieve 13-bit resolution for precise control applications.
• Accuracy and Temperature Error: At 25°C, basic error limits stay at ±0.1% for input ranges. Temperature error reaches ±0.1% up to 55°C for inputs. Outputs show ±0.3% basic error and ±0.6% temperature error.
• Protection and Diagnostics: Includes diagnostic alarms for wire breaks and short circuits. Monitors supply voltage with LED status indicators for inputs and outputs. A maintenance LED alerts you to module issues.
• Environmental Specifications: Operates from -20°C to 60°C horizontally or -20°C to 50°C vertically. Survives storage from -40°C to 70°C with 95% humidity (no condensation). Meets IP20 protection rating for industrial control cabinets.
