The inputs deliver 14-bit resolution with overrange (12-bit without), and the outputs resolve to 11/12 bit — enough for most process-value monitoring and control loops where a 16-bit card would be overkill. Optical isolation separates the analog circuitry from the backplane bus, which means a fault on the field wiring — a shorted transmitter loop or a voltage spike on the output — stays on the field side and does not take out the rack power supply or the CPU. ## Panel fit and mechanical constraints The module is 120 mm deep, 40 mm wide, and 125 mm tall — standard S7-300 single-width format. It snaps onto the DIN rail and connects to the backplane bus via the 20-pin front connector. If you are retrofitting into an existing rack, verify that the slot is free and that the front connector wiring (20-pin) matches your existing field-wire termination scheme.","metaTitle":"Siemens 6ES7335-7HG02-0AB0 SM 335 Analog Module, 4 AI / 4 AO","metaDescription":"Siemens 6ES7335-7HG02-0AB0 SIMATIC S7-300 analog module SM 335, 4 AI 14-bit, 4 AO 11/12-bit, optically isolated.
