Phoenix Contact EMG 17-REL/KSR- 24/21-21-LC Relay Module — 2940391

DIN rail industrial relay module with DPDT contacts, 24V AC/DC coil

Overview

The Phoenix Contact EMG 17-REL/KSR-24/21-21-LC (Order No. 2940391) is a DIN rail-mounted industrial relay module featuring a non-latching 24V AC/DC coil and DPDT (2 Form C) silver-nickel contacts rated for 5A. With a fast typical response time of 8ms and a maximum switching voltage of 250V AC/DC, this module is a reliable component for signal isolation and switching tasks within industrial control panels.

Key Features

  • DPDT contact configuration: 2 Form C contacts provide flexible switching arrangements for control circuits.
  • Silver-nickel contact material: AgNi contacts offer reliable conductivity and durability under repeated switching.
  • Fast response time: Typical response time of just 8ms for quick-acting control applications.
  • High switching voltage capability: Rated up to 250V AC/DC with a 5A continuous current rating.
  • Robust inrush handling: Supports a maximum inrush current of 6A.
  • Compact DIN rail mounting: Slim 17.5mm width for space-efficient panel installation.
  • High dielectric strength: Test voltage of 4kV AC (winding/contact) and 1kV AC (contact/contact) for reliable electrical isolation.
