Chapter 1 – Introduction
1.1 General Description
Remote Automation Solution’s ControlWave Loop Power Supply
(herein referred to as the “Loop Supply”) provides regulated and
isolated 24Vdc power outputs that can be used to power field devices
such as transmitters or non-isolated I/O circuits that are used in
conjunction with ControlWave MICRO, EFM, GFC, Express or Express
PAC units. Encapsulated loop Supply’s, i.e., those with the printed
circuit board (PCB) secured to a Power Supply Back Plate Bracket and
protected by a Power Supply Board Cover, may be mounted directly to
a panel or to a 35mm DIN Rail while the PCB only version can be Snap
Track mounted.
Loop Supplies provides a 24Vdc field power distribution via four pairs
of wiring terminals provided on Terminal Block TB2. Additionally,
Loop suppliess are user configured via Jumper JP1 to operate in
conjunction with either a nominal bulk 12Vdc input (with an input range
of +9 to +30Vdc) or a nominal bulk 24Vdc input (with an input range of
+19 to +30Vdc). Loop supplies have been designed to provide the
following features:
4-Loop Power Terminal pairs provide field device wiring flexibility
and convenience.
9-30 Vdc bulk power input range accommodated installation
flexibility.
Bulk power input can be applied to either of the three-terminal
connectors (with one Terminal Block accommodating input wiring
while the other may accommodate non-isolated power pass-through
that is used to power the ControlWave Micro, ControlWave EFM,
ControlWave GFC, ControlWave Express or ControlWave Express
PAC.
Direct Panel, 35mm DIN Rail or Snap Track Mounting
accommodated.
Small size minimizes panel space requirements.

1.2 Loop Supply Component Identification
Loop Supplies components that the user should become familiar with
are discussed herein. These components include Connectors TB1, TB2
and TB3, Configuration Jumper JP1, the Power LED, and Fuse F1.

ControlWave Loop Power Supply
Terminal Blocks
Loop Supply’s are provided with three Terminal Blocks which
accommodate up to #16 AWG size wire. Terminal Block
Connections are provided in Tables 1-1 and 1-2.
Terminal Block TB1 typically acts as the interface for the bulk 9 to
30 Vdc input power. In some cases, TB1 may be used as the bulk dc
power pass-through interface to an associated RTU in lieu of
Terminal Block TB3. It should be noted that TB1 & TB3 can be
used for Input Power or Power Pass-through with one
accommodating input while the other may accommodate passthrough, e.g. if TB1 was used to interface bulk Input Power, then
TB3 could be used to accommodate Power Pass-through, or viceversa.

Configuration Jumper P1
Jumper JP1 is used to set the input voltage range, i.e., 9V to 30V
(nominal 12V input) or 19V to 30V (nominal 24V input).
o JP1 – 1 to 2: 12V Input: ON above 8.4V, (Max. ON = 8.8V),
OFF below 8.24V (Min. OFF = 7.8V) (Factory Configuration)
o JP1 – 2 to 3: 24V Input: ON above 18.8V, (Max. ON = 19.7V),
OFF below 18.4V (Min. OFF = 17.4V)
Power LED
Red LED (CR10) will be ON when regulated 24V is present. When
lit, CR10 indicates that the Loop Supply is operational.
Fuse F1
Fuse F1 (2A Slow Blow 5 x 20 mm) provides protection for the
Loop Supply and the associated field I/O (powered by Loop
Supply). If a short circuit should occur in I/O field wiring or
circuitry within the Loop Supply, F1 will blow and the regulated
24V output will switch OFF.
Note: Power Pass-through is not fused since the ControlWave
GFCs/RTU provide their own fuse protection.
