Description
The Siemens SIMATIC S7-1200 Analog Input Signal Board SB 1231 (6ES7231-4HA30-0XB0) is a compact analog input module designed for the S7-1200 PLC series. This signal board provides 1 analog input channel with 12-bit resolution, supporting ±10V DC voltage signals or 0-20mA current signals. Featuring an extremely short conversion time of 156.25 µs, it allows direct connection of analog sensors without additional amplifiers. The module can be directly inserted into the front panel of any S7-1200 CPU, enabling controller expansion without occupying additional control cabinet space. With its compact 38mm×62mm×21mm dimensions and DIN rail mounting capability, it offers flexible solutions for space-constrained automation applications.
