MAXI-AMP CR Series Specifications
SUPPLY VOLTAGE:
ac, 50/60Hz (4 VA), or 12 to 28V dc* at 70mA.
Models CR3(R)B, and CR5(R)B: 210 to 250V ac, 50/60Hz (4 VA), or 12 to
28V dc* at 70mA.
*NOTE: do not connect ac power if using external dc power.
OUTPUT CONFIGURATION:
Models CR3A, CR3B, CR5A, CR5B have an SPST solid-state relay for switch-
ing ac or dc (see page 1).
Models CR3RA, CR3RB, CR5RA, CR5RB have an SPDT electromechanical
(e/m) relay with the following ratings:
CONTACT RATING: 250V ac max, 24V dc max, 5 amps max. (resistive
load), 1/10 H.P. at 240V ac. Install transient suppressor (MOV) across contacts
which switch inductive loads.
CONTACT RESPONSE: 10 milliseconds max. open/close;
20 operations/second max.
MECHANICAL LIFE: 20,000,000 operations
CR3 models also have a logic level current sinking NPN transistor switch
at pin #9. See schematic (right) and hookup info.
AMPLIFIER:
RESPONSE SPEED: programmable for 10, 2, or 0.3 milliseconds. NOTE:
use 10 millisecond setting whenever possible for enhanced noise rejection.
HYSTERESIS: if programmed "HIGH", approximately 20%; if programmed
"LOW", approximately 5%. NOTE: see cautions for "LOW" setting (see page
5).
MODULATION FREQUENCY: approximately 10kHz.
SENSOR LEAD LENGTH:
shielded cable for emitter and receiver, or order sensors with extended cable
length. NOTE: see splicing precautions.
MULTIPLE SENSOR HOOKUP:
together to one CR Series amplifier for "OR" operation (in LIGHT operate) or
"NAND" operation (in DARK operate). Emitters are connected in series, and
receivers are connected in parallel. When wiring two sensors to one MAXI-
AMP, multiply excess gain data for each sensor by 1/2 (obtain data from ap-
plicable excess gain curve). When wiring three sensors to one MAXI-AMP,
multiply excess gain by 1/3.
TIMERS (CR5 models only):
TIMING RANGES:
REPEATABILITY:
ADJUSTMENTS:
operate, amplifier response time, amplifier hysteresis, normally open or normally
closed output, and timing function (CR5 models). 15-turn clutched potentiometer
for gain and time setting(s) (CR5 models).
OPERATING TEMPERATURE:
INDICATOR LEDs:
is energized. Exclusive Banner Alignment Indicating Device (AID™) system
lights a red LED indicator whenever the receiver "sees" its own modulated
light source, and pulses it at a rate which is proportional to the strength of the
received light signal.
CONSTRUCTION:
ing, 1.6" x 2.3" x 4". Standard round-pin 11-pole plug base.
NOTE: If MAXI-AMP is powered by a dc power supply, connect +12 to 28V dc
@ ≥70mA to terminal #3 and dc common to terminal #1.
Make no connections to terminal #7 or #8.

Functional Schematics
CR5 Models
NOTE #1: power is available at pins #3 (+) and #1 (-) for an external 10 to 30V dc
device (see hookup example, page 4). Current available is 40 mA at 120V ac (240V
ac) line level; 30mA at 105V ac (210V ac) line level. Alternately, the module may
be powered by 12 to 28V dc at pins #3 (+) and #1 (-). Do not connect ac voltage
if using external dc power.
NOTE #2: pulling pin #9 low (to common) will inhibit the timing, or reset the latch
of CR5 model (see "Description of Logic Functions", page 6).
CR3 Models
NOTE #3: pin #9 of CR3 model may be connected directly to the AUXILIARY
input of a MAXI-AMP or Banner M Series module. It may also serve as the input
to Banner CL series MAXI-AMPs or to Banner Plug Logic modules.
