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.

 CONFIGURATION AND OPTIONS

 CONNECTOR CABLE PIN CONFIGURATION

The connections required between the FX2C, FX2NC main unit and a terminal block are shown in the dia-gram below with an example for inputs X000 to X017 and outputs Y000 to Y017. The I/O connector should be the 20-pin type and should conform to MIL C 83503 of Military Standard.

 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.

DIRECT INPUT BLOCKS AND DIRECT OUTPUT BLOCKS WIRING

Internal circuit

•  (9) and (19) of both CN1 and CN2 are short-circuited internally.

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 parallel, 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.

FX-16EYT-ES-TB/UL, FX-16EYT-TB (sink)
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.
