WARNING
!

IMR01N02-E2
i-2
This is a Class A instrument. In a domestic environment, this instrument may cause radio
interference, in which case the user may be required to take adequate measures.
This instrument is protected from electric shock by reinforced insulation. Provide
reinforced insulation between the wire for the input signal and the wires for instrument
power supply, source of power and loads.
Be sure to provide an appropriate surge control circuit respectively for the following:
- If input/output or signal lines within the building are longer than 30 meters.
- If input/output or signal lines leave the building, regardless the length.
This instrument is designed for installation in an enclosed instrumentation panel. All
high-voltage connections such as power supply terminals must be enclosed in the
instrumentation panel to avoid electric shock by operating personnel.
All precautions described in this manual should be taken to avoid damage to the
instrument or equipment.
All wiring must be in accordance with local codes and regulations.
All wiring must be completed before power is turned on to prevent electric shock,
instrument failure, or incorrect action.
The power must be turned off before repairing work for input break and output failure
including replacement of sensor, contactor or SSR, and all wiring must be completed
before power is turned on again.
To prevent instrument damage or failure, protect the power line and the input/output lines
from high currents with a protection device such as fuse, circuit breaker, etc.
Prevent metal fragments or lead wire scraps from falling inside instrument case to avoid
electric shock, fire or malfunction.
Tighten each terminal screw to the specified torque found in the manual to avoid electric
shock, fire or malfunction.
For proper operation of this instrument, provide adequate ventilation for heat dispensation.
Do not connect wires to unused terminals as this will interfere with proper operation of the
instrument.
Turn off the power supply before cleaning the instrument.
Do not use a volatile solvent such as paint thinner to clean the instrument. Deformation or
discoloration will occur. Use a soft, dry cloth to remove stains from the instrument.
To avoid damage to instrument display, do not rub with an abrasive material or push front
panel with a hard object.
Do not connect modular connectors to telephone line.

1. OUTLINE
This Chapter describes features, package contents and model code, etc.
1.1 Features
The digital controller of this high performance type has the following features:

High-speed sampling time (25 ms)
Suitable for fast responding control systems.

Autotuning function corresponding to fast response
• The HA400/HA900 is best suited for applications that reach setpoint quickly (within 30 seconds). *
• The HA401/HA901 is best suited for applications that take more than 30 seconds to reach setpoint. *
* Autotuning a process with a fast response may produce PID constants that would fluctuate the process excessively. If the process is less than
5 minutes to setpoint, RKC recommends adjusting the AT differential gap to less than 10 seconds (default value in the HA401/HA901) prior
to autotuning.

Up to two input 2-loop control in one instrument
Control mode is selectable from 1 loop control, 2-loop control (2 input type only) and cascade control.

Direct function keys
Three Direct Function Keys on the front panel are provided for one-key operation to switch Auto/Manual,
Remote/Local, and RUN/STOP.

Up to 16 memory areas or ramp/soak control
HA400/HA900/HA401/HA901 can store up to 16 sets of control parameters. Ramp/Soak control is available by
using the memory area function.

Two communication ports (option)
HA400/HA900/HA401/HA901 incorporates a maximum of two communication ports to communicate with a
computer, operation panel, programmable controller, etc.
1.2 Checking the Product
Before using this product, check each of the following:

1.4 Outline of Functions
This section describes the input/output functions of the instrument. To learn how to set each function, see the
respective page.
 INPUT In addition to measured input, 5 optional input functions are available.
Measured input: 1-input or 2-input. (Specify when ordering)
Input types available for measured inputs are shown in the table below.
Thermocouple * : K, J, T, S, R, E, B, PLII, N, W5Re/W26Re
RTD * : Pt100, JPt100 [Factory set value: Pt100]
Voltage (low) * : 0 to 100 mV DC, 0 to 10 mV DC, 0 to 1 V DC [Factory set value: 0 to 1 V DC]
Voltage (High) * : 0 to 5 V DC, 1 to 5 V DC, DC 0 to 10 V DC [Factory set value: 1 to 5 V DC]
Current * : 0 to 20 mA DC, 4 to 20 mA DC [Factory set value: 4 to 20 mA DC]
*To change the input type, see 9. ENGINEERING MODE (P. 50).
The second measured input can be used as isolated remote input.
Event input: Optional Event Input hardware is necessary. (Specify when ordering)
Event Input can be used for the following functions. (See P. 70.)
Memory area transfer (Number of areas:1 to 16 or 1 to 8)
Operation mode transfer (RUN/STOP, Remote/Local, Auto/Manual.)
Remote input (non-isolated type):
 Remote input is to change a control setpoint by using current or voltage input from an
external device.
 Remote input is available with 1-input controller. (Specify when ordering)
 Measured input at Input 1 is not isolated from remote input at Input 2. If isolated remote
input is necessary, specify 2-input controller when ordering, and use the second input for
remote input.
Any one of the following input types can be selected. (See P. 66.)
Voltage (low) : 0 to 100 mV DC, 0 to 10 mV DC, 0 to 1 V DC
Voltage (High) : 0 to 5 V DC, 1 to 5 V DC, DC 0 to 10 V DC
Current : 0 to 20 mA DC, 4 to 20 mA DC
CT input: CT input is used for Heater Break Alarm function to detect a heater break or short-circuit.
Up to two CT inputs can be selected. (Specify when ordering)
 Only one CT input is available when power feed forward input is selected.
 Measured input is not isolated from CT input.
CT inputs accept signal from dedicated current transformers (CT).
Two types of CT available. (See P. 80.)
CTL-6-P-N (for 0 to 30 A)
CTL-12-S56-10L-N (for 0 to 100 A)

Power feed forward (PFF) input:
Power feed forward input is used for Power Feed Forward function to achieve accurate
control. PFF monitors power supply voltage variation on a device and compensates
control output from the controller.
Two types of dedicated transformer is available. (Specify either of them when ordering)
PFT-01 100 V type transformer (100 to 120 V AC)
PFT-02 200 V type transformer (200 to 240 V AC)
Feedback resistance input:
Feedback resistance input is used to monitor a valve position when position proportioning
PID control is selected as control action.
Measured input is not isolated from feedback resistance input.
 OUTPUT Up to five outputs are available. They may be used as control output, event output or
transmission output by specifying the output type or by activating the output logic
function (output logic selection).
Output1 to 3 (OUT1 to OUT3):
 Control output, event output, HBA alarm output, or transmission output can be allocated
to output 1 to 3. (See P. 72 to 81.)
 Number of outputs and output types must be specified when ordering.
Output types available for OUT1 to OUT3 are shown in the table below.
Relay contact output 250 V AC, 3A (Resistive load), 1a contact
Voltage pulse output 0/12 V DC (Load resistance: 600 Ωor more)
Triac output 0.4 A (Rated current)
Voltage output 0 to 5 V DC, 1 to 5 V DC, 0 to 10 V DC (Load resistance: 1 kΩor more)
Current output 0 to 20 mA DC, 4 to 20 mA DC (Load resistance: 600 Ωor less)
 OUT3 is isolated from both OUT1 and OUT2.
 OUT1 and OUT2 are not isolated from each other except for relay or triac output.
When relay or triac output is used, there is isolation between outputs.
There is isolation between input and output.
 There is isolation between output and power supply terminals.
Output 4 to 5 (OUT4 to OUT5):
The output type for OUT4 and OUT5 is relay only. OUT4 and OUT5 can be used for
event output and/or HBA alarm output. (See P. 72 to 81.)
Relay contact output 250 V AC, 1A (Resistive load), 1a contact
Event output function (EV1 to EV4)
The following event types can be selected for EV1 to EV4.
Deviation high Band SV high 
Deviation low Process high SV low 
Deviation high/low Process low LBA (Only EV3 and EV4 can be selected)
 The maximum number of event output is four.
 Output allocation is necessary to output the event state from output terminals. (See P. 72.)
