Product Overview
Upgrading legacy control systems demands reliable hardware. The Siemens 6ES7455-0VS00-0AE0 SIMATIC S7-400 FM 455 C control module delivers 16 channels of continuous closed-loop control, combining 8/16 analog inputs, 16 digital inputs, and 16 analog outputs in a single module. This 6ES7455-0VS00-0AE0 is designed to replace older, less flexible controllers, providing enhanced accuracy and expandability.
Technical Specifications Breakdown
The Siemens 6ES7455-0VS00-0AE0 operates on a 24 V DC supply (range 20.4 V to 28.8 V) with typical power loss of 12 W (max. 17.3 W). It features 16 digital inputs per IEC 61131 Type 2, accepting 24 V DC signals. Analog inputs accept voltages (0-10 V, -1.75 to +11.75 V, ±80 mV), currents (0-20 mA, 4-20 mA, etc.), thermocouples (Types B, J, K, R, S), and Pt100 RTDs. Resolution is parameterizable up to 14 bits. Analog outputs provide voltage (0-10 V, ±10 V) and current (0-20 mA, 4-20 mA, ±20 mA) with settling times as low as 0.1 ms for resistive loads.
- Digital inputs: 16, signal “1” at 13-30 V, typ. 7 mA
- Analog inputs: 16 (thermocouple/2-wire) or 8 (Pt100/4-wire)
- Analog outputs: 16, short-circuit protected
- Resolution: 12 or 14 bit, parameterizable
- Dimensions: 50 x 290 x 210 mm, weight approx. 1,400 g
Industry Applications
This Siemens 6ES7455-0VS00-0AE0 excels in continuous process control, such as temperature profiling in furnaces (using thermocouple Types B, J, K, R, S) or precise flow regulation with 4-20 mA loops. Its 16 independent controllers can manage multiple PID loops simultaneously, making it ideal for chemical reactors, extrusion lines, and environmental test chambers. The upgrade potential is clear: replace older 8-channel modules with this 16-channel unit to reduce rack space and wiring complexity.
Installation & Setup Guidance
Mount the Siemens 6ES7455-0VS00-0AE0 in a S7-400 rack. Two 48-pin front connectors are required (not included). For analog inputs, use shielded cable (max. 200 m, 50 m for 80 mV/thermocouple signals). Digital input cables can run up to 1,000 m shielded or 600 m unshielded. Ensure supply voltage is within 20.4–28.8 V DC. Parameterize resolution and temperature compensation via STEP 7. For thermocouples, enable internal or external Pt100 compensation as needed.
Selection Guide & Purchasing Advice
Before purchasing a Siemens 6ES7455-0VS00-0AE0, verify compatibility with your S7-400 CPU firmware and backplane bus. The module requires two 48-pin front connectors (order separately).
