FAIL Alarm – 2sets. SPDT rated 5 A @ 120 VAC
High Voltage Variable from 450 to 1500 VDC @ 0.2 mA
Detector Power
± 15 v @ 20 mA
Recorder/Computer
Outputs
Two 4 to 20 mA (500
Ω load max. each), and one 0 to 10 VDC (1 KΩ load
min.), scaled to the ratemeter range
For the 942A-200L-M4 only, two additional analog outputs are provided
from the Model 942-200-95-M1 Dual analog Output Option board. The
ranges are 0-10mV and 0-5 VDC (1Kohm load min.). For further
information, refer to the 942-200-95D Analog Output Option Instruction
Manual, provided separately.
Remote Alarm Ack
Input
Optically isolated DC input
Detector Input
Digital pulse train. Detector may be located up to 1500 feet from the
ratemeter. Individually adjusted upper and lower level discriminators limit
MeV response to desired range.
Statistical Accuracy
Statistical accuracy is user selectable at 2%, 5%, 10%, or fixed at a one
second update. Count time automatically adjusts per selected accuracy
and count rate (not recommended for safety related applications).
UDR Electronic
Accuracy
± 1% of the displayed value (± 1 digit)
Single Channel
Analyzer
For the 942A-200L-M4 only, a Model 942-200-90-M1 Single Channel
Analyzer option circuit board is provided. This board provided the ability to
perform pulse height analysism by counting the only pulses that fall
between two adjustable voltage windows. For further information, refer to
the 942-100-90D Single Channel Analyzer Instruction Manual, Provided
separately.
