Chapter 1. PRODUCT OUTLINE
1 - 1 Features
The DCP552 is a general purpose dual-loop control programmer for controlling temperature, pressure, flow rate,
carbon potential (CP) and other parameters. The program provides a total of 49 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
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 O
2
sensor inputs for carbon potential compensation.
● Multi-control output types
Selection at setup allows the user to choose from among current proportional
output, voltage time proportional output and open collector time proportional
output.
● Multi-communications
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
terminal base to the front panel loader jack. A special cable is required to use to
loader jack on the front panel.
● Improved PLC support
The programmer is equipped with 16 external switch inputs and 16 event outputs
for flexible support of PLC based automatic systems.
● Simple operation
The optional plug-in memory card makes it easy to achieve program and
parameter settings for later reuse. Also, the optional smart loader package allows
you to make program and parameter settings from a PC.
