FC SERIES MANUAL LOADER
(STEP OUTPUT TYPE)
DATA SHEET
PND3
One is used for remote control in combination with a compact controller, while the other is dedicated for manual operation.
This instrument is equipped with a solid state indicator and
pushbutton operation circuit to provide easy readouts and
handling for process operation by man-machine communication.
It can be directly connected to a thermocouple, resistance
bulb or 4 to 20mA input optionally.
FEATURES
1. High reliability
The manual loader is a solid state instrument having few
mechanical parts. The indicator and other units which
formerly consisted of mechanical parts are also designed
with solid state circuits to provide high reliability.
2. Application of international standards
This instrument is compact, and the external dimensions
comply with international IEC. The power supply and
signal also comply with IEC standards (24V, 1 to 5V DC).
Operation on 100V or 200V AC power supply is possible.
3. Front panel operation
Process values, valve position input, etc. can be read
accurately from the digital display on the panel front.
Parameter setting and manual operation are also possible
from the front of the panel.
