Note’s on the symbology used in this manual
At various times through out this manual certain symbols will be used to highlight points of infor-
mation which are intended to ensure the users personal safety and protect the integrity of the
equipment. Whenever any of the following symbols are encountered, its associated note must be
read and understood. Each of the symbols used will now be listed with a brief description of its

1) Indicates that the identified danger WILL cause physical and property damage.
2) Indicates that the identified danger could POSSIBLY cause physical and property damage.
1. INTRODUCTION
Terminal blocks convert I/O terminals of connector type PLC into terminal blocks. Some terminal blocks
directly extend inputs and outputs of PLC. Other terminal blocks are equipped with diversified built-in
devices, and function only as inputs or only as outputs.

5. TERMINAL WIRING
Never perform external wiring to unused terminals . Such wiring may damage the unit.
Note
✩Do not lay I/O cables next to power cables or allow them to share the
same trunking duct.
✩Where I/O signals are used over an extended distance consideration
must be made for voltage drop and noise interference.
✩Use crimp-style terminals of the dimensions shown in the figure below.
✩Tighten terminals at a torque of 0.5 to 0.8 N·m (4.4 to 7.1 lbf·in). Do not
tighten the terminal block mounting screws with a torque outside the
above-mentioned range. Failure to do so may cause equipment failures or malfunctions.

Relay output blocks FX-16EYR-ES-TB/UL, FX-16EYR-TB wiring
Terminal blocks are not equipped with built-in fuses. In order to prevent breakdown of circuits caused by
load short-circuit, provide a fuse of 5 to 10 A for every four points.
[ DC LOAD ]
Connect a noise suppression diode to a DC inductive load in parallel.
If the diode is not connected, the life time of the contact becomes
considerably shorter.
Select a noise suppression diode whose reverse withstand voltage is
5 to 10 times or more the load voltage and whose current in the for-
ward direction is not less than the load current.
[ AC LOAD ]
When a surge absorber is connected to an AC inductive load in paral-
lel, noise generation is reduced.
0.1 F capacitor + 100 to 120 resistor
The standard life time of contactors and solenoid valves against AC inductive load is 500,000 times of
actuation against 35 VA.
The table below shows the guideline of the life time of relays based on the result of the life time test per-
formed in our company.
Have in mind that the life time of a relay contact becomes considerably shorter even in the condition below
if the rush current is shut down.
Triac output block FX-16EYS-ES-TB/UL wiring
Terminal blocks are not equipped with built-in fuses. In order to prevent breakdown of circuits caused by
load short-circuit, provide a fuse of 5 to 10 A for every four points.
[ MINUTE CURRENT LOAD ]
To a neon lamp or a minute current load of 0.4VA/100V AC, 1.6VA/200V
AC or less, connect a surge absorber in parallel.
[ OUTPUT CURRENT ]
The current of 0.3 A can flow in each output point. However, in order to restrict temperature rise, flow 0.8
A to every four output points (= 0.2 A per point on an average). When turning on and off frequently a load
with large rush current, set the square average current to 0.2 A or less.

Terminal blocks are not equipped with built-in fuses. In order to prevent breakdown of circuits caused by
load short-circuit, provide a fuse of 2 A for every four points.
[ ON VOLTAGE ]
The ON voltage of an output transistor is approximately 1.5 V.
When driving a semiconductor device, etc., pay attention to the input voltage characteristics of the used
device.
