5094-IA16

Overview of Allen Bradley 5094-IA16

The Allen Bradley 5094-IA16 is a 16-point digital AC input module from the Flex 5000 series, engineered for industrial automation systems. It accepts input voltages in the range of 74 to 132 Volts AC at frequencies from 47 to 63 Hz, with a nominal rating of 120 Volts AC. This module is designed to provide reliable digital input data, suitable for harsh environments with an operating temperature range of -40 to +70 °C. The 5094-IA16 draws its field-side power from an external source and is typically mounted on DIN rails for ease of installation. Its robust design includes off-state current suppression and an input filter to reduce signal noise, ensuring precise and stable performance in control applications.
