6AG1214-1BG40-4XB0 - Siemens PLC S7-1200 CPU 1214C AC DC

The Siemens PLC S7-1200 CPU 1214C AC DC 6AG1214-1BG40-4XB0 is a rugged Programmable Logic Controller (PLC) engineered by Siemens under the SIPLUS S7-1200 series. Built for industrial reliability, this CPU 1214C AC/DC/Relay variant includes conformal coating and is designed to perform in environments that demand consistent uptime, temperature tolerance, and robust I/O integration.

The 6AG1214-1BG40-4XB0 is derived from the standard 6ES7214-1BG40-0XB0 and upgraded with Siemens’ SIPLUS enhancements for industrial-grade durability. It operates within a temperature range of -20°C to +60°C, supported by a conformal coating that protects the internal electronics from humidity, dust, and chemical exposure. This CPU 1214C AC/DC/RLY model supports a wide input power range of AC 85–264 V at 47–63 Hz. Equipped with 14 digital inputs (24 V DC), 10 relay outputs rated at 2 A, and 2 analog inputs (0–10 V DC), it provides flexible control for both discrete automation and analog sensor feedback. The controller includes 100 KB of program/data memory, ideal for managing complex control logic, timers, and communication blocks in medium-scale automation systems. Compact in design, the unit measures 11.00 x 11.50 x 8.00 cm and weighs 0.464 kg, making it easy to integrate into tight control panel spaces. As a PM300: Active Product Lifecycle offering, the 6AG1214-1BG40-4XB0 is fully supported with Siemens firmware updates, long-term availability, and global service access.

Applications of Siemens PLC 6AG1214-1BG40-4XB0

The Siemens PLC S7-1200 CPU 1214C AC/DC/RLY 6AG1214-1BG40-4XB0 is ideal for use in industries such as manufacturing, utilities, water treatment, HVAC systems, and power infrastructure, where environmental conditions and electrical reliability are critical. The onboard relay outputs simplify control of motors, alarms, and contactors—eliminating the need for external relays—while the analog inputs provide accurate measurement capabilities for temperature, level, and pressure sensors. Its conformal-coated electronics and wide voltage range make it particularly suited for semi-outdoor panels, substations, and factory environments exposed to fluctuating temperature or humidity. System integrators and automation engineers benefit from compatibility with Siemens TIA Portal for rapid deployment, diagnostics, and scalability. For panel builders and OEMs, the 6AG1214-1BG40-4XB0 delivers a reliable, space-saving solution backed by Siemens' global reputation and long-term lifecycle support.
