PRODUCT INFORMATION
Product Overview
The Allen-Bradley 1762SC-IF8U is a MicroLogix universal analog input module manufactured by Spectrum Controls. Spectrum Controls developed this expansion module as an Allen-Bradley Encompass partner product for 1762 MicroLogix systems. It features eight channels for voltage, current, and thermocouple sensors. Up to four channels can be configured for resistance temperature detector or resistance inputs.
The module converts field signals using an internal 16-bit analog-to-digital converter. Supported signal formats include engineering units, scaled-for-PID values, and raw proportional data. Each channel includes individual selectable filter frequencies of 4 Hz, 17 Hz, 62 Hz, and 470 Hz. The hardware mounts directly onto a standard DIN rail or panel mounting plate. Maximum thermal dissipation is rated at 1.4 W during standard operation.
