Introduction 1

1.Introduction

The FX2N-5A analog special function block has four input channels and one output channel. The input channels receive analog signals and converts them to the comparable digital values. The output channel takes a digital value and outputs an equivalent analog signal.

1)Analog signal inputs can be selected from either voltage or current input. The applicable analog signal input is set using the TO instruction supplied by the PLC main unit.

This PLC instruction is used to select different analog input signal types for each corresponding channel.

2)The FX2N-5A can be connect to FX0N/FX1N/FX2N/FX2NC/FX3U/FX3UC series PLC

3)Up to 2 FX2N-5A units can be connected to FX0N main unit, FX0N extension unit, FX1N Main unit.

Up to 8 FX2N-5A units can be connected to FX2N/FX3U/FX3UC*1 Series PLC. Up to 4 FX2N-5A units can be connected to one FX2NC Series PLC.

For connection to the FX2NC Series PLC, an FX2NC-CNV-IF is required.

For connection to the FX3UC Series PLC, an FX2NC-CNV-IF or FX3UC-1PS-5V is required. Data transfer with the PLC is performed via buffer memories of the FX2N-5A using FROM/ TO Instructions.

*1 Up to 7 units can be connected to an FX3UC-32MT-LT PLC.

3.Installation

Install the FX2N-5A to the right side of a main unit, extension unit, extension block or special block of the FX0N/FX1N/FX2N/FX2NC/FX3U/FX3UC Series PLC.

The FX2N-5A can be installed with DIN rail (DIN46277 of 35 mm in width) or directly installed with screws M4. For the details, refer to the handy manual supplied together with the PLC main unit.)

•The FX2N-5A can be installed on DIN rail (DIN46277) of 35 mm in width as it is. For removal, pull down on the DIN rail mounting hook, then remove the FX2N-5A.

•The FX2N-5A can be installed directly by inserting screws (M4) into installation holes. For the pitch and the position of installation holes, refer to the figure on the left.

Connection to PLC 4

4.Connection to PLC

Connect the FX2N-5A to the right side of a main unit, extension unit or extension block of FX0N/ FX1N/FX2N/FX2NC/FX3U/FX3UC Series PLC with an extension cable.

For connection to a basic unit or extension block of the FX2NC Series PLC, use an FX2NC-CNV- IF.

For connection to a basic unit or extension block of the FX3UC Series PLC, use an FX2NC-CNV- IF or FX3UC-1PS-5V.

Please check the power supply availability to determine the number of FX2N-5A blocks that can be connected to the FX0N/FX1N/FX2N/FX2NC/FX3U/FX3UC PLCs.

A unit No. 0 to 7 is automatically assigned to each special unit or special block connected to a PLC basic unit from the one nearest to the basic unit.*1

The data is read from and written to the FX2N-5A by FROM/TO instructions supplied by the main unit.

*1 Because the unit No.0 is assigned to the built-in CC-Link/LT master in the FX3UC-32MT-LT, unit numbers assigned to special extension units/blocks begins with No.1.

5.1Caution

1) Do not lay signal cabling near to high voltage power cabling or house them in the same trunking duct. Effects of noise or surge induction may occur. Keep signal cables at safe distance of more than 100 mm (3.94") from these power cables.

2)The terminal screws of the FX2N-5A are M3 (0.12"), therefore crimp style terminals (see drawing) suitable for use with these screws should be fitted to the cable for wiring.

		or less

3)The terminal tightening torque is 0.5 to 0.8 Nxm. Tighten securely to avoid malfunction.

4)Cut off all phases of power source before installation or performing wiring work in order to avoid electric shock or product damage.

5)Remount the provided terminal cover before supplying power and operating the unit after installation or wiring work in order to avoid electric shock.

*1 Use a two-core, shielded twisted pair for the analog input line, and separate it from other power lines or a lines easily induced.

*2 If there is voltage ripple in the input signal or there is noise in the external wiring, connect a bipolar capacitor of approximately 0.1 to 0.47 µF, 25 V.

*3 For the current input, short-circuit the “V+” terminal and the “I+” terminal.

*4 Make sure to connect the terminal to the terminal of the PLC basic unit to which Class D grounding (100 Ω or less) is performed.

*5 The 24 V DC service power supply of the PLC is also available.

-For the terminal arrangement, refer to Section 2.

*1 Use a twisted pair shielded cable for the analog output. This cable should be wired away from power lines or any other lines which could induce noise.

*2 Apply 1-point grounding at the load side of the output cable (grounding: 100Ω or less).

*3 If electrical noise or a voltage ripple exists at the output, connect a smoothing capacitor of

0.1to 0.47µF, 25V.

-Shorting the voltage output terminal or connecting the current output load to the voltage output terminal may damage the FX2N-5A.

-For the terminal arrangement, refer to Section 2.
