Product details

The 6ES7123-1JA00-0AB0: Single-channel analog input module for the SIMATIC S7-1200, measuring Pt100, Ni100, and 0-600 ohm resistance. Runs on 24 V DC from the backplane bus, drawing up to 30 mA. Rated for continuous operation with a typical power loss of 0.6 W.

Occupies one slot out of eight on the rail, with a physical profile of 10 mm wide, 64 mm tall, and 51 mm deep. Uses the TB 16SC terminal block; shielded cable runs up to 50 m. The narrow width leaves room for additional modules in the same row.

Measurement and filtering

Integrating measurement; basic conversion time 110/130 ms. Digital filtering in four stages (1x, 8x, 64x, 128x cycle time). Crosstalk ≥50 dB at line frequency; common-mode rejection ≥90 dB. Linearity error ±0.05%.
