Relay provides flexible safety provisions
The Duelco NST2004 is a Category 4 (EN954-1) safety relay with three normally open safety contacts and either a normally closed relay output or a transistor signal output.
The Duelco NST2004 is a Category 4 (EN954-1) safety relay with three normally open safety contacts and either a normally closed relay output or a transistor signal output (DIP switch selectable).
There are two housings, a standard 22.5mm version and a 22.5mm version with detachable terminals, which is ideal from a maintenance perspective.
Supply options are 24V DC and 24, 48, 115 or 230V AC.
An internal PTC fuse regenerates itself on power up should a wiring fault or error be present.
All versions have current limited outputs making them suitable for safety switches, mats and edges as well as light curtains and emergency stop buttons.
Three LEDs show power, diagnostic and status information.
