Thank you very much for purchasing a Multi-Channel Board Controller.
The Multi-Channel Board Controller outputs control signals that match an input from
a thermocouple (a K/J thermocouple) or an input from a temperature input from a
resistance bulb (Pt100/JPt100) to a predetermined setting.
The product comes equipped with an RS-485 or an RS-232C for data
communications with a host computer.
For control output, the product is provided with up to eight open collector outputs,
along with event outputs consisting of 11 open collector outputs (eight temperature
alarm outputs, one heater wire break alarm, one SSR breakdown alarm, and one error
alarm), eight current detector inputs, and one voltage input.
Please read this detailed manual carefully and use this product correctly.

3. Installation
3.1 How to install the product
• See "3.3 Outside dimensions" and install the product with nine screws (φ3.5).
• Install the board as floated by at least 5mm with a spacer or something similar.
• Install it horizontally. Or install it vertically with its power supply facing upwards.
• When installing two or more products of this kind, install them at least 50mm apart.
• Connecting crimp terminals: Use crimp terminals of specified dimensions (M3, no more than
6.9mm wide).
• Connecting exposed wires: Use wiring of AWG22 to 16.
• Terminal screws: Tighten them to a specified torque (about 0.5N-m). A loose screw may cause a
fire or malfunction.
3.2 Where to install the product

4.3 Cautions on making the connections
configured to a "sensitivity" of 0.
point" to change the ON/OFF point without changing the
Warning
• Before making the connections, turn off this product. Otherwise you may get an electrical shock.
Warnings
• This product will not begin control for about 10 seconds after being turned on. (It will not activate its
outputs or other components.) Be careful if you wish to use the product as an interlocking circuit.
• Check the operation manual and other documents to ensure that you make the correct connections for
the temperature input terminal, power terminal, and other terminals.
• To connect a resistance bulb to this product, use wiring having a line resistance of no more than
5Ω per wire.
• To connect a thermocouple to this product, use a specified kind of compensating lead wire or
element wire.
• Use a shielded wire if you wish to use this product near a noise source. Do not wire an
input/output line in the same duct or conduit tube.
• Separate the input/output signal lines at least 50cm from the power line and load line.
5. Before conducting control
Selecting PID control Selecting ON/OFF control
This product is factory-configured to a "proportional
band" of 3.0. This product can conduct control in that
state. For better control, however, auto-tune (AT) this
product. AT automatically sets settings (values P, I, and
D) required for control. For AT, put this product into an
actual operating state (a state where the sensor input,
control output, and other components are wired). AT
takes some time.
This product is factoryIf conducting control causes the relay to flutter, increase
the sensitivity to reduce the flutter. If conducting
control causes this product to stabilize at a level lower
than the set temperature, increase the parameter "OFF
setting.
6. Table of identifiers (codes)
a) Identifier: A code that represents an item. Enter the code into the identifier field in the message.
(The code is a three-digit figure.) The □ in the frame represents SP (:space:ASCII code...20H).
b) Name: Item name
c) R/W: Specifies which function (read or write) is possible for an identifier into the current memory
bank, or whether both of those functions are possible.
r/w: Specifies which function (read or write) is possible for a memory bank other than the current
one, or whether both of these functions are possible. (This identifier can be read and written in a
memory bank.)
d) Description: Gives a description and specifies a set range and other details.
