DESCRIPTION

The Model APSIS is a convenient plug-in unregulated +24 VDC power

supply designed to “load share” when connected in parallel with other +24

VDC unregulated systems with unusual power requirements due to sensor or

accessory loading (see Fig.1). It can also be used as a general purpose stand-

alone supply to power +24 VDC control circuits, sensors and accessories (see

Fig.2). In addition, two 20 mA Current Source outputs are available, each

capable of powering up to 16 Serial Communications units (see Fig.3). The

APSIS is available in 115 and 230 VAC ±10%, 50/60 Hz. primary supply (see

Ordering Information). Operating temperature range is -20°C to +50°C.

SPECIFICATIONS

1. POWER SOURCE: 2 versions, 115 VAC or 230 VAC ±10%, 50/60 Hz., 11

VA max. (see Ordering Information).

2. POWER OUTPUT: +24 VDC unregulated @ 200 mA max. current*,

Ripple = 1.5 V P-P max.

3. OUTPUT: Two 20 mA current sources, each capable of supplying 20 mA of

current for serial communication loops and powering up to 16 units per loop.

4. OPERATING TEMPERATURE: -20°C to +50°C (-4°F to +122°F)

* Maximum available output current derates to 175 mA with 1 source active

and 150 mA max. with both sources active.

TEMPERATURE MONITORING SYSTEM

A temperature monitoring process requires both remote

and control room indicators and datalogging capabilities.

An RTD (Resistance Temperature Detector) to 4 to 20 mA

Transmitter, provides a proportional 4 to 20 mA output

from the RTD input. Two Red Lion Controls “Loop

Powered Process Indicators” (Model LPPI) are installed

in series in the “Loop” and scaled to provide Local and

Remote temperature displays. A Datalogger is also placed

in the “Loop” to provide a hard-copy of process

temperatures. Each device in the “Loop” has an associated

“voltage drop” as follows: RTD Transmitter = 9 VDC

drop; LPPI = 3 VDC x 2 units = 6 VDC drop; Datalogger

= 5 VDC drop. The total voltage drops in the “Loop” =

20 VDC. Therefore, RLC’s Model APSIS, with its +24

VDC Supply, is used to power this process “Loop”.
