Datasheet DELCON Series Relays The optimal interface relay for hazardous locations Delcon Series Relays help to eliminate interference, signal disturbances, inductive loads, high DC voltages, and costly relay replacements. 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 EXO 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.

A back-emf clamping diode with the load must be used when switching inductive loads. Fusing To protect relay against short circuit and overload a fast fuse with the correct rating for the load and the capacity of the relay should be chosen. Note that when overload current is not large, it is possible that the fuse will not protect the relay because of the tolerance on the fuse rating.

A back-emf clamping diode with the load must be used when switching DC inductive loads. Functional block diagram When controlling inductive AC loads, there is no need to use extra protection elements such as a RC circuit or snubbers with the load. The surge current is not allowed to exceed the specification. For reasons of heat dissipation, when the load will be switched frequently, the Mechanical Dimensions average current over a reasonable time should not exceed the specification for continuous operation. Fusing To protect relay against short circuit and overload a fast fuse with the correct rating for the load and the capacity of the relay should be chosen. Note that when overload current is not large, it is possible that the fuse will not protect the relay because of the tolerance on the fuse rating.
