A-B 1746SC-INO4I

The 1746SC-INO4I is an analog output module compatible with the Allen-Bradley SLC 500 system, produced by Spectrum Controls. Here's a detailed description: **General Information** - It belongs to the 1746 SLC 500 series. This module is designed for specific applications within the SLC 500 framework, ensuring seamless integration with other components of the system. - It's an analog pure current output module, focusing on delivering precise current-based output signals. **Electrical Characteristics** - Input Voltage Range: Accepts an input voltage typically within 0 - 5V. - Output Current Range: Can provide output signals such as 0 - 20mA, 0 - 21mA, and 4 - 20mA. - Resolution: With a 16-bit resolution, it offers a high level of precision. The current per count is 366 nanoamps and the voltage per count is 320 microvolts. - Number of Channels: It has four isolated channel outputs. Each channel can be programmed and configured independently. - Electrical Isolation: It features excellent electrical isolation. The optoelectronic isolation between channels and from field wiring to the backplane is 750V DC, reducing noise crosstalk.

**Power Requirements** - Backplane Power: Draws 120 mA at 5V DC from the backplane. - External Power: Can also interface with an external 24V DC power supply to minimize current load on the backplane. A DIP switch on the module is used to specify the power source. **Performance Parameters** - Step Response Time: Has a step response time of 1 ms, enabling quick response to input signal changes. - Update Time: The maximum update time for all 4 parallel channels is 33.7 ms. - Accuracy: Achieves an accuracy of 0.08% of full scale at 25°C and 0.15% at 60°C. - Heat Dissipation: The maximum heat dissipation power is 4.5 W.

**Other Features** - Certification: It has passed UL/CUL Class I, Division 2, Groups A, B, C, D and CE certifications, ensuring safety and reliability. - Easy Configuration: Can be easily configured using ladder diagram registers or RSLogix programming software. - Temperature Compensation: Features on-board ambient temperature compensation to handle temperature fluctuations within the cabinet.
