■POWER INPUT RATING & OPERATIONAL RANGE
• Locate the power input rating marked on the product and confirm its operational range as indicated below:
85 – 132V AC rating: 85 – 132V, 47 – 66 Hz, approx. 4VA
24V DC rating: 24V ±10%, approx. 4W, approx. 160mA
■GENERAL PRECAUTIONS
• Before you remove the unit or mount it, turn off the power supply, input signal and output signal for safety.
■ENVIRONMENT
• Indoor use.
• When heavy dust or metal particles are present in the air, install the unit inside proper housing with sufficient ventilation.
• Do not install the unit where it is subjected to continuous vibration. Do not subject the unit to physical impact.
• Environmental temperature must be within -5 to +55°C (23 to 131°F) with relative humidity within 30 to 90% RH in order
to ensure adequate life span and operation.
■WIRING
• Do not install cables close to noise sources (relay drive cable, high frequency line, etc.).
• Do not bind these cables together with those in which noises are present. Do not install them in the same duct.
■AND ....
• The unit is designed to function as soon as power is supplied, however, a warm up for 10 minutes is required for satisfying
complete performance described in the data sheet.

9. POINTS OF CAUTION IN CONNECTING WIRES
Appropriate precautions are required such as follows for protecting the system from external noise interference:
1) Separate analog I/O and communication wires from others in order to prevent surge or induction noises.
2) Separate power input wires (AC) from those for driving motors.
3) Do not install these wires next to main supply circuits or high voltage cables.
Never bind them to these circuits.
4) Ground the shield of communication wires at one point.
Consideration about locations of the ground may be necessary according to external noise interference.

10. I/O SIGNALS
10.1 REMOTE I/O
The 61C occupies from 1 up to 4 nodes according to the number of I/O channels. Regardless of the number of nodes, 32 bits
are assigned to each of input and output for sending to/receiving from the Master Unit. One (1) bit among RXxB* is used as
remote device (61C) READY signal, turned ON when the 61C is in normal operation.
*. x = (Station No. × 2 – 1) H
[example] Station No. = 9
9 × 2 – 1 = 17 511H
READY signal is input at RX11B.
10.2 ASSIGNING REMOTE REGISTERS
(1) 61C-x1, 61C-163
The 61C-x1 does not use the remote registers for the direction from the Master to Remote (RWwn to RWwn+15).
The table below shows the data assignment of those for the direction from the Remote to Master.

(3) OUTPUT IN AN ABNORMALITY
When an abnormality such like CPU error, STOP, time-out occurs at the PLC, the output signal of the 61C is maintained as
HOLD (no clearing output signal, keeping the value just before the abnormality).
When the PLC recovers to normal operation and the 61C receives new data, the output restarts changing.

12.TROUBLESHOOTING
Basic troubleshooting methods are explained in this section.
For problems concerning the PLC CPU and Master Unit, consult users manuals for these units.
12.1 L ERR. INDICATOR BLINKING
CHECK TROUBLESHOOTING
Have you changed the station No. and/or baud rate set-
tings during normal operation?
Return these settings to the state when the unit operated normally.
12.2 L ERR. INDICATOR ON
CHECK TROUBLESHOOTING
Are the station No. and/or baud rate settings correct? Set them correctly.
12.3 L RUN INDICATOR OFF
Consult the users manual for the Master Unit.
12.4 UNABLE TO READ/WRITE DIGITAL VALUES?
CHECK TROUBLESHOOTING
Is the L RUN indicator OFF? Refer to Section “12.3 L RUN INDICATOR OFF”.
Is the L ERR. indicator blinking or OFF? Consult the users manual for the Master Unit.
Is the RUN indicator on the PLC CPU blinking or OFF? Consult the users manual for the CPU.
Is the RUN indicator on the Master Unit OFF? Consult the users manual for the Master Unit.
Are the RD/SD indicators on the Master Unit ON? Consult the users manual for the Master Unit.
Are the wires for analog I/O properly connected to respec-
tive terminals? No wire breakdown?
Check these wires visually or check conductivity for each pair of
wires.
[61C-x1, 61C-163]
Remove analog input wires and apply test voltage to the
terminals (e.g. Use a dry cell). Try to read out digital
value.
If the digital value is read out normally, there are possibilities of
noise interference via external wires. Check wiring and grounding.
[61C-x2, 61C-163]
Remove analog output wires and connect a tester to the
terminals. Try to read out digital value.
If the digital value is read out normally, there are possibilities of
noise interference via external wires. Check wiring and grounding.
13.LIGHTNING SURGE PROTECTION
We offer a series of lightning surge protectors for protection against induced lightning surges. Please contact us to choose
appropriate models.
