WARNING
CAUTION
Use the DCP301 within the operating ranges recommended in the specifica-
tions (temperature, humidity, voltage, vibration, shock, mounting direction,
atmosphere, etc.). Failure to do so might cause fire or faulty operation.
Do not block ventilation holes. Doing so might cause fire or faulty operation.
Wire the DCP301 properly according to predetermined standards. Also wire
the DCP301 using designed power leads according to recognized installa-
tion methods.
Failure to do so might cause electric shock, fire or faulty operation.
Do not allow lead clippings, chips or water to enter the controller case.
Doing so might cause fire or faulty operation.
Inputs to the current input terminals (31) and (33) on the DCP301 should be
within the current and voltage ranges listed in the specifications.
Firmly tighten the terminal screws at the torque listed in the specifications.
Insufficient tightening of terminal screws might cause electric shock or fire.
Do not use unused terminals on the DCP301 as relay terminals.
Doing so might cause electric shock, fire or faulty operation.
We recommend attaching the terminal cover (sold separately) after wiring
the DCP301. Failure to do so might cause electric shock, fire or faulty opera-
tion.
Use the relays on the DCP301 within the service life listed in the specifica-
tions.
Continued use of the relays after the recommended service life might cause
fire or faulty operation.
Before connecting the DCP301 to the measurement target or external con-
trol circuits, make sure that the FG terminal is properly grounded (100Ω
max.).
Failure to do so might cause electric shock or fire.
Before wiring, or removing/mounting the DCP301, be sure to turn the power
OFF. Failure to do so might cause electric shock.
Do not touch electrically charged parts such as the power terminals. Doing
so might cause electric shock.
Do not disassemble the DCP301. Doing so might cause electric shock or
faulty operation.

iii
CAUTION
Use induced lighting surge preventive device if there is the risk of power
surges caused by lightning.
Failure to do might cause fire or faulty operation.
Before replacing the battery, be sure to turn the power OFF. Failure to do so
might cause electric shock.
Do not touch internal components immediately after turning the power OFF
to replace the battery. Doing so might cause burns.
･Do not insert the battery with the polarities (+,-) reversed.
･Do not use damaged (broken battery skin, leaking battery fluid) batteries.
･Do not throw batteries into fires, or charge, short-circuit, disassemble or
heat batteries.
･Store batteries in low-temperature, dry locations.
Failure to observe the above cautions may cause batteries to emit heat or
split, or battery fluid to lead.
Store batteries out of the reach of small children.
Batteries are small and are easy to swallow. If a child swallows a battery,
consult a physician immediately.
Return used batteries to Honeywell sales/service office or your dealer. When
disposing of used batteries at the user site, observe local by laws.
Handling Precautions
After turning the power ON, do not operate the DCP301 for at least 15s
to allow the DCP301 to stabilize.

Chapter 1. GENERAL
1-1 Features
The DCP301 is a general-purpose single-loop program controller for controlling temperature, pressure, flow rate and
other inputs.
●High accuracy achieved by multi-range input
Multi-range input allows you to choose between the following input types: thermocouple,
resistance temperature detector (RTD), dc voltage and dc current. Accuracy of ±0.1%FS±1
digit and a sampling cycle of 0.1s ensures consistently high-precision control.
●Wide range of control output types
A wide range of models supporting various control output types are available: relay time-
proportional output, position-proportional output, current output, voltage time-propor-
tional output, and heat/cool output.
On models other than heat-cool control output, you can also choose neural net-based
auto-tuning and smart-tuning for inhibiting overshoot, in addition 2 degrees of freedom
PID.
●Enhanced compatibility with PLC
12 external switch inputs (eight optional), three event outputs and five time event outputs
(optional) ensure compatibility with automating systems designed around a PLC core.
●Easy operation
Up to eight frequently changed parameter setups can be registered to the PARA key, facili-
tating recall of item setups.
If the Smart Loader Package (sold separately) is used together with the DCP301, pro-
grams and parameters can be set up on a personal computer.

2-2 Console
The console comprises keys for operating the controller, displays and LEDs.
■Basic display state
The “basic display state” is the state in which the controller operating state is displayed
on the console.
When the power is turned ON, the controller is in this state.
Key operation changes the controller from the basic display state to one of the parameter
setup, program setup, program copy or general reset states. Key operation also returns
the controller to the basic display state.
