PCM-8D is 8-input pulse counter, intended to connect tax
instruments or other devices, which do not have any interface,
but pulse outputs. One PCM-8D can connect maximum of 8 devices
with pulse output. They are double powered - normally power
supply is from the network, but if network failed for some
reason, they switch to internal battery powered supply.
This backup battery assures minimum 96h work time w/o external
power supply. When network voltage is up again, the battery
is recharged. to full capacity. Battery status is regularly
displayed in volts, so user knows when he must replace the
battery, if needed.
PCM-8D has embedded real time clock and calendar, which
allows to track up to four time tariffs for each input.
Collected pulses for each tariff, and total pulses for each
input are saved in separate registers and are read through
display or modbus network. Tariff defining can be done only
via modbus interface, all other parameters can be set through
device keyboard.
For client purposes PCM-8 have two-line, 16 symbol each
line LCD display. The user can check in any moment collected
pulses on each input or tariffs, cost of the pulses, medium
measured (m3, кWh, etc.), battery status, device's address
in modbus network, etc.
Devices of that kind can be connected to mutual modbus
network and all set-up and reading can be centralized (controller
with modbus, PC, etc).
