The module provides eight isolated relay outputs for switching AC or DC industrial loads from a modular SIMATIC S7-300 station.
Its 40-pole front-connector design supports individually isolated channels, while the documented switching capacity suits contactors, valves, lamps and signaling circuits. Verify load voltage, current and external protection before commissioning.
This SM 322 module translates controller output data into eight individually isolated relay contacts. It supports 24 V DC or AC load circuits up to the documented contact ratings and is intended for established S7-300 automation systems. A 40-pole front connector is used for field wiring, and external short-circuit protection must be selected for the connected loads.
SIMATIC modules follow coordinated rack, addressing and STEP 7 engineering concepts for structured industrial automation.
Documented electrical limits, module data and lifecycle information support controlled maintenance and replacement planning.
Relay switching for contactors, valves, lamps, alarms and auxiliary circuits in production machinery and process skids.
Expansion or lifecycle maintenance of installed SIMATIC S7-300 systems requiring individually isolated relay contacts.
