Allen-Bradley 1734-IE4S POINT Guard I/O 4-Channel Safety Analog Input Module
- Brand
- Allen-Bradley
- Model
- 1734-IE4S
- GEARWELL SKU
- GWP-000004172
- Category
- PLCs & I/O
Key specifications
- Field power supply
- 24 V DC nominal; 19.2…28.8 V DC, Class 2. For UL installations, power the module and connected devices from one Class 2 supply. For Series A, use 24 V DC maximum and follow 1734-CTM spacing requirements above 40 °C.
- Product type
- POINT Guard I/O safety analog input module
- Configurable input ranges
- Voltage: ±5 V, ±10 V, 0…5 V or 0…10 V; current: 0…20 mA or 4…20 mA; tachometer: 1…1000 Hz. In bipolar voltage modes, a broken wire can read as valid zero without a fault indication.
- Sensor power supply
- 24 V DC; 150 mA maximum per point at 55 °C and 600 mA aggregate per module. Sensor power outputs are not safety digital outputs.
- ADC resolution and data format
- 12-bit ADC; 16-bit two's-complement data format.

The Allen-Bradley 1734-IE4S is a POINT Guard I/O safety analog input module with 4 single-ended inputs that are software-configurable for ±5V, ±10V, 0…5V, 0…10V, 0…20 mA, 4…20 mA or tachometer (1…1000 Hz), with 12-bit ADC resolution and 24V DC sensor power outputs. It is rated up to SIL 3 (IEC 61508) and Category 4/PLe (EN ISO 13849-1) and needs two terminal bases.
