SIPLUS S7-300 DIGITAL INPUTS
Conformal-coated discrete input acquisition for SIPLUS S7-300 installations.
Siemens 6AG1321-1BL00-2AA0 is a SIPLUS S7-300 SM 321 digital input module with 32 isolated inputs rated for 24 V DC signals. It uses a 40-pole connection and incorporates conformal coating. The product description specifies a temperature range of -40 to +70 degrees Celsius; installation conditions and simultaneous-input limits must be observed. The module acquires discrete field states for processing in a compatible S7-300 control system. Selection for maintenance should account for the exact order number, connector arrangement, supply conditions, and existing hardware configuration. Siemens currently identifies this article as a spare part with PM410: Product cancellation status.

Compatible field devices provide 24 V DC input states.
→
The isolated digital inputs acquire discrete states for the S7-300 system.
→
The control program uses the input states for sequencing, status monitoring, and equipment logic.
Match 6AG1321-1BL00-2AA0 to the configured S7-300 hardware and the 40-pole wiring arrangement. Observe the official limits for mounting orientation, ambient temperature, and simultaneous active inputs. Conformal coating does not remove the need for suitable enclosure and installation practices.
It provides 32 isolated digital inputs rated for 24 V DC.
The product description specifies one 40-pole connection.
No blanket assumption should be made. The data sheet specifies simultaneous-input limits according to installation and temperature.
Siemens lists PM410: Product cancellation, effective October 1, 2025, and identifies this article as a spare part.
