1-1 Features

The DCP551 is a general purpose single-loop control programmer for controlling temperature, pressure, flow rate
and other parameters. The program provides a total of 99 patterns and up to 99 segments can be set for each pattern.
Note, however, that the maximum number of segments is 2000 or less and that the maximum number of subfunctions
for setting events is 4000 or less.
High accuracy in multi-range inputs
Multi-control output types
Multi-communications
Improved PLC support
Simple operation
Featuring a multi-range format, the user can select thermocouple, resistance temperature
detector, DC voltage or DC current. Accuracy is ±0.1% FS ±1 digit, the sampling cycles
is 0.1 sec and some model numbers allow PV2 channel switching.
Selection at setup allows the user to choose from among current proportional setting
output, current proportional output, voltage time proportional output and open collector
time proportional output.
Selection at setup enables the user to switch between RS-485 and RS-232C on the rear
panel terminal base.
At setup it is also possible to switch the communications port from the rear panel termi-
nal base to the front panel loader jack. A special cable is required to use to loader jack on
the front panel.
The programmer is equipped with 16 external switch inputs and 16 event outputs for
flexible support of PLC based automatic systems.
The optional plug-in memory card makes it easy to achieve program and parameter set-
tings for later reuse. Also, the optional smart loader package allows you to make pro-
gram and parameter settings from a PC.
