S8T-DCBU-02 – Power management control range
with new DC buffer unit
The S8T-DCBU-02 is a buffer block that is designed to prevent interruptions in equipment operation, loss
of data or other problems resulting from a momentary power loss. It does this by providing a back-up power
source as well as a shutdown time off process for at least 500ms (at 2.5A) to 1s (at 1A) in the event of a glitch
or transient interruptions in the power supply.
The S8T-DCBU-02 can be used with all of Omron’s power supplies, and is one of the most cost-efficient ways
of ensuring the supply of power in industrial automation systems. Up to four such buffer blocks can
be connected in parallel to increase the back-up time and current handling capacity. The S8T-DCBU-02
operates by using built-in capacitors that act as a temporary power source during a power failure. In addition,
the capacitors charge the energy that has been increasingly generated by a boosted charging voltage to them,
to deliver more power and provide a longer back-up time than can be expected from a standard back-up
system. When the power supply recovers, these capacitors start recharging. Like other Omron power supplies,
built-in over-current and over-voltage protection circuits in the buffer block protect equipment against damage
caused by shorts and overloads.
Sockets
Omron offers a wide range of sockets into which products like relays, timers and controllers can be connected.
The most innovative of these is the Screw-Less Clamp (SLC) socket, which offers an effective, timesaving,
no-compromise wiring solution in industrial environments. With SLC sockets wiring time is drastically reduced,
routine maintenance is eliminated and a very reliable connection is assured. Because there are no screws
to be tightened during initial wiring there’s is no over- or under-tightening of cable connections and
no damaged threads. Once the clamp secures the wire, it stays secured, eliminating the risk of the wiring
coming loose through shock or vibration.
Omron also provides a range of Screw Terminal Sockets, with and without external clips, which are suitable
for both DIN-rail and surface mounting. In addition, Omron has a range of solder terminals, plug-in terminals,
PCB terminals and wire-wrap terminals, which are suitable for back-mounting and which are also available
with and without external clips.
