The Siemens 6AG1326-1BK02-2AB0 Digital Input Module is part of the SIPLUS S7-300 SM 326F family and is designed for fail-safe digital signal acquisition in SIMATIC S7 F-systems.
Unlike conventional digital input modules used only for standard control logic, the SM 326F DI24 is intended for safety-related applications where field signals may form part of a machine or process safety function. Its 24 fail-safe inputs can be used to monitor safety switches, emergency-stop devices, interlocks, proximity sensors and other suitable field devices.
The module is based on the 6ES7326-1BK02-0AB0 and uses a 40-pole front connector for field wiring. The 24 inputs operate at a nominal 24 V DC and provide defined voltage thresholds for reliable signal recognition.
The module also includes integrated safety functions and diagnostic capabilities. These features allow it to participate in an appropriately engineered SIMATIC F-system and provide useful information when an input channel or associated wiring does not behave as expected.
Environmental protection is another important characteristic of the SIPLUS version. The module has conformal coating and is designed for an operating temperature range of -25°C to +60°C, with operation up to +70°C possible when forced convection is provided according to the specified conditions.
The 6AG1326-1BK02-2AB0 also supports applications where environmental conditions are more demanding than those normally found in a clean control room. Its environmental specifications cover a range of chemically active and industrial conditions, making it suitable for selected process and machinery applications.
With dimensions of 80 × 125 × 120 mm and a user-specified weight of 0.495 kg (1.09 lb), the module provides 24 fail-safe input channels in a relatively compact S7-300 module format.
For engineers maintaining existing S7-300 safety systems, this module can be an important replacement or expansion component where fail-safe digital input processing and SIPLUS environmental protection are required.
