Ametek SC-7404-N Input Signal Conditioning Module

Ametek SC-7404-N is a single-input, dual-relay module in the SC-7400 family of signal conditioners that converts a process signal into two independent SPDT relay outputs for alarms or interlocks. The device supports software-configurable trip points and output behavior via the PC-7400-3 configuration kit, allowing precise thresholds without changing hardware; all input and output parameters can be set through Windows-based software for repeatable performance. Powering options include 24 VDC, 48 VDC, 110 VDC, or 120 VAC at 50/60 Hz, enabling flexible integration with standard control systems, while its design aligns with the SC-7400 convention of detachable field wiring from the DIN mounting base to simplify replacement and maintenance. This module is well-suited for industrial monitoring where a single input must trigger two relays—useful for redundant alarms, interlock schemes, or separate control routines—thanks to its dual SPDT contacts and configurable trip logic. Compatible with standard DIN-rail or panel installations, the SC-7404-N follows the SC-7400 design approach, including detachable field wiring and Windows-based configuration, making field replacement and diagnostics straightforward.
