CPU 314C-2 PtP: integrated I/O and PtP interface
The Siemens 6ES7314-6BH04-0AB0 is a SIMATIC S7-300 CPU 314C-2 PtP with 24 digital inputs and 16 digital outputs on-board, plus 4 analog inputs (0 to 10 V or 0/4 to 20 mA) and 2 analog outputs (0 to 10 V).
Programming and engineering environment
Programmable in LAD, FBD, STL, SCL, and GRAPH — the full IEC 61131-3 set plus CFC for continuous-function-chart engineering. Requires STEP 7 V5.5 + SP1 or higher (or V5.3 + SP2 with HSP 203). Supports 8 function blocks (FM 8) and 8 system function blocks (SFB type). The I2t rating of 0.7 A²·s applies to the integrated digital outputs — relevant for short-circuit protection coordination.
Physical dimensions and mounting
120 mm wide, 125 mm high, 130 mm deep — occupies 8 slots on a standard S7-300 DIN rail. The 0 °C to 60 °C operating range covers most cabinet environments without forced cooling.
