FC SERIES
COMPACT CALCULATOR
DATA SHEET
PNM2
The FC series compact calculator is a high cost-performance, flexible, and highly functional calculator which inputs
5 analog signals and 6 digital signals, digitally performs complex calculations such as arithmetic, square root extraction,
time-factor calculations, etc., and then provides 5 analog
and 6 digital outputs.
FEATURES
1. Highly functional calculator using a microprocessor
A variety of calculating functions are coordinated into
functional units called wafers. Complex calculations are
thus performed flexibly and accurately through connection
of the computational wafers.
2. International standards
This instrument is compact in size, conforming to international standards IEC. It operates on 24V DC power to
deliver 1 to 5V DC signals as recommended by IEC standards.
100V and 200V AC power are also available for convenience of operation.
3. Contents of calculation are changeable on the spot
The contents of calculation can be specified on the spot
using key operation on the front panel. And the contents
are retained even at power failure due to utilization of a
non-volatile memory.

1. Computational functions
(1) Wafers
The wafer is a functional software package which realizes
the computational functions needed for instrumentation control. A calculator which responds flexibly to the application
purpose is realized through combination of these wafers
having their own individual functions.
The PNM is capable of executing a total of either 24, 48 or
64 wafers. The wafers given in the table below are standardequipped which enables selection according to the purpose of
application.
• For computation: A variety of computations are feasible by
combining the wafers in Table 1.
(2) Internal input/output terminals
Various internal terminals for connecting external analog
input/outputs and digital input/outputs with wafers are provided.
(3) Constants
These can be freely defined as parameters for use in calculation. (32 constants with 24 wafers, 48 constants with 48
wafers, 64 constants with 64 wafers)
(4) Computation cycle
0.2 sec (24 wafer type)
0.4 sec (48 wafer type)
0.5 sec (64 wafer type)
