The 1756-OF8IH ControlLogix HART Output Module, manufactured by Allen-Bradley, is a sophisticated 8-channel module designed for installation in any 1756 I/O chassis slot. It features 8 isolated differential current outputs, each equipped with an independent HART modem, and supports an output range of 0-20mA and 4-20mA with a high resolution of 15 bits, optimizing performance across a 24mA span. Offering robust protection, the module includes open circuit detection and over-voltage protection at ±24V DC, while its electronic short-circuit limit ensures outputs do not exceed 21mA. Additionally, it boasts effective output isolation of 250V between channels, rapid HART scan times of 1 second, and maintains operational efficiency within a temperature range of 0-60 °C, ensuring reliable performance in diverse industrial environments.
