Siemens6ES5420-3BA11Digital Input Module, 32 Inputs, 24 V DC, Non-Isolated, Compact K Format, SIMATIC S5

Product Description

What this part is: Siemens SIMATIC S5 digital input module. Brand: Siemens. Part Number: 6ES5420-3BA11. Module Type: 420 digital input. Inputs: 32. Input Voltage: 24 V DC. Isolation: non-isolated. Form Factor: compact version K. Controller Platform: SIMATIC S5. Unit Quantity: 1 Pc. Country of Origin: Germany. Decoding the order code: 6ES5 — the Siemens order-number group for SIMATIC S5 automation hardware. 420 — the module type number for the digital input module. 3 — the compact K module format. BA11 — the execution code setting 32 inputs at 24 V DC, non-isolated. What these specs mean in practice: Inputs: 32. Input Voltage: 24 V DC. Isolation: non-isolated. Thirty-two channels on one card is the highest input density in the 420 range, so a machine with a large count of limit switches, proximity sensors and pushbuttons consumes fewer rack slots. Non-isolated construction ties all inputs to a common system reference, which is the arrangement used where every field device already sits on the same 24 V supply as the controller. Mounting data: Mounting Type: plug-in module for a SIMATIC S5 rack slot. Connector Style: front-panel field wiring connector, backplane connector to the rack. Quantity and configuration: Unit Quantity: 1 Pc. Module only. Condition: new. Interchange guidance: Manufacturer Status: discontinued. Searchable forms of the number: 6ES5420-3BA11, 6ES5 420-3BA11, 6ES5420 3BA11 and 6ES54203BA11. The execution code after the dash sets the channel count, voltage and isolation, so the whole string is the element to match.
