ABB 2TLA010050R0000 Sentry SSR10 Safety Relay 24VDC

The ABB Sentry SSR10 (article 2TLA010050R0000) is a safety relay with 3NO + 1NC relay outputs, a 24 VDC supply voltage, and screw terminals. It monitors safety devices with contacts on one or two equivalent channels as well as safety devices with OSSD outputs. The Sentry SSR10 series covers safety applications up to PLe / SIL3, making it suitable for a broad range of machine safety requirements.

Technical specifications:

• Series: Sentry SSR10
• ABB article number: 2TLA010050R0000
• EAN: 7350024483284
• Output contacts: 3NO + 1NC relay outputs
• Supply voltage: 24 VDC
• Terminal type: Screw terminals
• Input compatibility: Safety devices with contacts (1 or 2 equivalent channels) and OSSD outputs
• Reset mode: Manual or automatic, selectable via front switch
• Safety performance: Up to PLe / SIL3

Features and benefits:

• Reset mode - manual or automatic - is selectable by a switch on the front panel, allowing adaptation to different machine safety architectures without rewiring.
