Delcon Series Relays

Pulse transformer technology for isolating I/O signals offers significant advantages over optical isolation and electromechanical relays. Most notably, pulse transformer I/O modules provide higher transient immunity and high input-to-output isolation.

The high transient immunity means the Weidmuller – Delcon I/O modules are ideal for I/O applications where electrical noise is a problem. No additional suppression components are needed even when used with long unshielded signal cables, inductive loads or ‘noisy’ power lines.

The limitations of optocoupler based solid-state relays disappear when pulse transformer I/O modules are used. For instance, the standard AC output module SLO 24TR has near zero leakage current; requires no minimum load; can be used with any power factor 0 to 1; is rated for both general use and inductive loads at 3A; and is immune to both load line and signal line spikes.
