3. 942-200-95: ANALOG OUTPUT BOARD - Designed to provide a user selectable single output
voltage of: 0 - 10 Vdc, 0 - 5 Vdc, 0 - 1 Vdc, 0 - 500 mVdc, 0 - 100 mVdc, 0 - 50 mVdc, or 0 - 10
mVdc.
4. 942-200-95M1: DUAL ANALOG OUTPUT BOARD - Designed to provide two user selectable output
voltages. Output #1 is either 0 - 5 Vdc, or 0 - 10 Vdc, while output #2 is either 0 - 10 mVdc, 0 - 50
mVdc, 0 - 100 mVdc, 0 - 500 mVdc, or 0 - 1 Vdc included in the 956A-201-M2.
5. S157033A2 Line Filter/Surge Suppressor Assembly Designed to provide EMI/RFI protection for two
956A Series digital ratemeters and 897A Series G-M detectors. The assembly consists of two (2)
separate and independent line conditioning circuits that provide filtered AC power to each 956A
Series ratemeter. The S157033A2 is designed to mount in the center section of the 948B-1A-5 dual
module rack chassis, to provide EMI/RFI protection for two (2) 956A Series ratemeters. The major
active components of the S157033A2 are two (2), 960SS-200 Surge suppressor circuit boards, two
(2), 92-9015-A Line Filters, and two (2) 14-235 ferrite cubes. The S157033A2 also contains AC line
and neutral fuses to protect the internal circuitry from over current conditions.
To meet the requirements of EPRI TR-102323-R1, for radiated fields above 80MHz, the low
discriminator in the detector preamplifier must be set to 1.0 volts. This setting has been incorporated
into the factory calibration of all 897A Series G-M detectors.
1.8 APPLICATION
The Model 956A-201-M2 UDR is used with all Victoreen 897A Series G-M Detectors. The detector
specific setpoints for the 956A-201-M2 UDR are configured by the user for the range of the particular
detector supplied. The detector/preamp, when connected to a UDR, will function as a single channel
digital area monitoring system. For additional information on various applications, please contact
