Digital Output Common Connections - Siemens TALON Series Technical Reference Manual

Digital Output Common Connections

Siemens Industry, Inc.
588-587
CAUTION
Digital Output contacts are not internally current-limited or protected against
transients. If needed, externally install an NEC-approved current limiting device,
Metal Oxide Varistor (MOV), or both. See the MOV table in the
Guidelines Manual
(588-581).
Common terminals are not internally connected.

The contacts are rated for a maximum of 250 Vac at 4A resistive or 3A inductive.

Each I/O point has a green LED for status indication.

The TXM1.6R-M module is also equipped with manual override switches. An

orange LED per override switch indicates override status individually per point.
Digital Output common is isolated for each relay and must be externally wired to other
DO common if needed.
DANGER
Digital Output modules connected to high voltage should incorporate a readily
accessible disconnect device outside the panel. All low voltage and high voltage
wiring must be routed separately within an enclosure so that low voltage and high
voltage wiring cannot come in contact with each other. High- and low-voltage
circuits cannot be located on adjacent terminals within a module.
DANGER
Separate knockouts should be used for high voltage and low voltage wiring.
Leave at least 2 inches (50.8 mm) of space between the Class 2 wires and other
wires in the panel.
