description
Remote Reset—Connection between terminals 5 and 6 latches triac output
in alarm state after set point is exceeded. Opening the connection will reset
the output to non-alarm state.
Set Point Accuracy— ± 10% of setting with repeatability of ± 2%. Circuitry
utilizes RMS detector.
Vibration Sensitive Axis—Perpendicular to base. Unit can be mounted in
any orientation without affecting setting.
Temperature Limits— -20°F to +140°F (-30°C to +60°C) including internal
transducer. -65°F to +190°F (-55°C to +88°C) for optional external transducer.
Humidity—1% to 100% (non-condensing).
Input Power—100-130 VAC 50/60 Hz standard. 200-260 VAC 50/60 Hz
optional. DC input power optional.
Enclosure—Rugged, water-tight, dust-tight, cast aluminum. Meets NEMA,
3, 4 and 12 standards. Optional CSA mark for Class I, Div 2, Grps B-D, Or
explosion proof Model 450. 440 - NEMA 4X.
Weight—440 - 1.6 kg (3.5 lb); 450 - 2.72 kg (6 lb)
Mounting—
1
⁄
4
" hardware, 3 mounting bosses
Terminals—All terminals will accept #12 AWG wire in clamping type yoke
without need for termination hardware. All hardware is captive.
Self Test—Test position on set point control and light emitting diode provide
functional test of trip circuitry, time delay and triac closure. Also permits on-line
calibration of switch.
Circuitry—Proprietary hybrid circuitry throughout for minimum size and maxi-
mum reliability in vibration environment.
Remote Transducer Option—The standard 440 includes a built-in transducer.
A separate transducer can be specified. Please request separate transducer
when placing order. The SA6200A accelerometer (100 mV/g) is recommended.
Analog Switch Option—Recommended in place of triac for DC operation or
light loads such as computer or PLCs:
AC/DC Solid-State
Contacts are optically isolated from input power.
Field settable N.O. or N.C.
170 mA continuous
Maximum off state leakage, 10 micro amps
No holding current required
Maximum voltage: 250V
