Datasheet
Pulse Transformer
Digital I/O Modules
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 dis-
appear 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 pilot duty at 3A; and is immune to
both load line and signal line spikes.
Features:
virtually no off-state leakage currents
high current and high voltage DC output versions
compact packaging
optional rail mounting base
high surge current rating
fast switching
large selection of input and output types
industry standard pin connection
UL recognized, caor CSA approved (not all modules
are CSA approved)
