The Siemens 6AG1326-1BK02-2AY0 Digital Input Module is a SIPLUS version of the S7-300 SM 326F DI24 fail-safe digital input module. It is designed to acquire safety-related 24 V DC signals and transfer them into a suitable SIMATIC S7 F-system.
The module is based on the standard 6ES7326-1BK02-0AB0 and provides 24 digital fail-safe inputs. This makes it suitable for applications where multiple safety signals need to be monitored, such as emergency stops, safety doors, protective devices, machine interlocks and other safety sensors.
A major characteristic of this particular model is its SIPLUS environmental design. The module uses conformal coating to improve protection of the electronic components against demanding environmental conditions. The -2AY0 variant additionally carries environmental conformity associated with EN 50155 T1 Category 1 Class A/B, making it a suitable choice for certain railway and transportation automation systems.
The input circuits are designed for 24 V DC signals. A voltage between +11 V and +28.8 V is interpreted as a logical "1", while -28.8 V to +5 V represents a logical "0". The module also provides diagnostic functions and diagnostic alarms, which can simplify troubleshooting in safety-related systems.
For field wiring, the module uses a 40-pole front connector. Shielded cable lengths of up to 200 m and unshielded cable lengths of up to 100 m are specified, although actual installation performance depends on the sensor type, wiring arrangement and electromagnetic environment.
The module also provides four isolated outputs with a rated current of 400 mA. These functions are part of the module's overall fail-safe architecture and should be evaluated according to the intended S7 F-system configuration.
With dimensions of 80 × 125 × 120 mm and a user-specified weight of 0.480 kg (1.06 lb), the 6AG1326-1BK02-2AY0 is a substantial S7-300 safety module intended for applications where reliability and environmental resistance are more important than minimum physical size.
