More Information

Overview Manuals Channel Organization Sensor Supply Diagnostics and Safety Wiring Limits

Features:

  • Twenty-four 24 V DC fail-safe digital inputs
  • Two isolated twelve-channel input groups
  • Four isolated sensor-supply outputs
Siemens 6ES7326-1BK02-0AB0 is the SM 326 input module that brings fail-safe field states into a SIMATIC S7 F-system.

Its grouped input structure separates twelve channels from the other twelve while preserving an electrical boundary to the backplane.

Module diagnostics, a diagnostic alarm and the SF indicator expose faults that affect the input assembly or its field circuits.

The Siemens 6ES7326-1BK02-0AB0 SM 326 Fail-Safe Digital Input Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Input Grouping

  • Channel count: Twenty-four digital inputs accept 24 V DC field states.
  • Group structure: The inputs are divided into two groups of twelve channels.
  • Electrical separation: Each twelve-channel group is isolated from the other group and from the backplane.
  • Connector: Field wiring terminates through the required 40-pin front connector.

Field-Circuit Power

  • Supply outputs: Four isolated outputs provide sensor power for the input circuits.
  • Output rating: Each documented sensor-supply path is rated for 400 mA.
  • Two-wire sensors: Two-wire operation is supported when the short-circuit test is disabled.
  • Quiescent current: The permitted two-wire sensor quiescent current is 2 mA maximum.

Fault Reporting

  • Diagnostic data: The controller can read module diagnostic information.
  • Alarm behavior: A diagnostic alarm can be generated for reported module conditions.
  • Status display: The SF indicator reports a fail-safe or group fault at module level.
  • Safety capability: The documented maximum classification reaches Category 4, PL e and SIL 3.

Signal Connections

  • Shielded wiring: Input circuits may extend to 200 m with shielded cable.
  • Unshielded wiring: The documented maximum is 100 m for unshielded cable.
  • Logical zero: Input voltage from -30 to +5 V DC is evaluated as signal 0.
  • Logical one: Input voltage from +11 to +30 V DC is evaluated as signal 1.
Description
Siemens 6ES7326-1BK02-0AB0 is an SM 326 fail-safe digital input module for SIMATIC S7 F-systems. Its twenty-four 24 V DC inputs receive field contact or sensor states and transfer them through the S7-300 backplane for evaluation by the fail-safe controller.

The inputs of 6ES7326-1BK02-0AB0 are divided into two isolated groups of twelve channels. Four isolated sensor-supply outputs feed the connected input circuits, while each group maintains its own electrical boundary from the other group and from the backplane.

Diagnostic information from 6ES7326-1BK02-0AB0 can be read by the controller, and the module can issue a diagnostic alarm while its SF indication reports a module-level fault. Input-delay, cable-length and permitted sensor-current limits therefore apply to the complete field circuit rather than to an isolated specification value.
