Siemens 6ES7234-4HE32-0XB0 SIMATIC S7-1200 Analog I/O SM 1234
The Siemens 6ES7234-4HE32-0XB0 is a SIMATIC S7-1200 SM 1234 analog input/output module combining 4 analog input channels and 2 analog output channels in one compact module. It supports ±10 V, ±5 V, ±2.5 V, 0–20 mA, and 4–20 mA input signals, while its outputs support −10 V to +10 V, 0–20 mA, and 4–20 mA signals with up to 14-bit voltage resolution and 13-bit current resolution. Its combined input and output capability makes it suitable for applications requiring both analog measurement and analog control within a single S7-1200 expansion module.
