Allen-Bradley 1734-IE4S Point Guard I/O Safety 4-Channel Analog Input Module

The Allen-Bradley 1734-IE4S POINT Guard I/O Safety 4-Channel Analog Input Module is a safety-rated analog input card used in distributed control systems to monitor up to four analog signals within GuardLogix and POINT Guard I/O architectures. This DIN-rail mounted module provides four current inputs (4–20 mA, application dependent) with channel-to-backplane isolation and communicates over the backplane via a Guard I/O adapter, making it suitable for expanding safety I/O in control panels, process skids, and automated machinery requiring certified analog input monitoring. Designed for functional safety compliance in industrial environments, the 1734-IE4S is commonly used to monitor safety-related transmitters and sensors for safe process control, hazardous area monitoring, and machine safety applications where reliable analog input performance is essential. Common replacements include Allen-Bradley 1734-IE4C and 1734-IB8S, as well as Siemens 6ES7136-6BA00-0CA0.
