Applications
- Fail-safe digital output control: Provides fail-safe digital output control through 8 F-DO channels with sinking-sourcing operation.
Key Features
- Fail-safe digital outputs: The SM 326 has 8 fail-safe digital outputs with F-DO 8×24 V DC/2 A sinking-sourcing operation.
- Supply and output current: Rated supply is 24 V DC at 1L+. The rated output current for signal "1" is 2 A; the permissible maximum is 2 A for horizontal installation from 0 to 40 °C and 1 A for vertical installation.
- Diagnostics and protection: The outputs have short-circuit protection. Diagnostic alarms are parameterizable, diagnostic information is readable, and the SF group error is indicated by a red LED.
- Electrical isolation: The digital outputs have potential separation between channels, between channels and the backplane bus, and between channels and the electronics power supply. Separation between channels is in groups of 4.
- Connection and dimensions: A 40-pin front connector is required. The module measures 80 mm wide, 125 mm high, and 120 mm deep, with an approximate weight of 465 g.
- Safety classification and lifecycle: The module achieves Cat. 4 according to EN 954-1, Performance Level e according to ISO 13849-1, and SIL 3 according to IEC 61508 in safety mode. Product cancellation.
