1.Introduction

The FX2NC-4AD analog input block (hereafter referred to as "FX2NC-4AD") converts 4 points of analog input values (voltage and current inputs) into digital values, and transfers them to the PLC main unit.

The FX2NC-4AD can be connected to the FX2NC Series PLC.

1)A combination of voltage and current analog inputs selectable via the PLC TO instruction should be used to configure the individual input channels.

2)The voltage input range can be selected within -10 to 10V, alternatively, the current input range can be selected within -20 to 20mA and 4 to 20mA.

The input characteristics can be adjusted for each channel (except when !=2, 5, 8 is set in BFM #0 that disables all changes to the offset or gain).

3)The resolution is 0.32 mV (20 V ⋅ 1/64,000) or 2.50 mV (20 V ⋅ 1/8,000) when voltage input is used, and 1.25 ∝A (40 mA ⋅ 1/32,000) or 5.00 ∝A (40 mA ⋅ 1/8,000) when current input is used.

4)Data transfer with the PLC is performed via the buffer memories of the FX2NC-4AD using FROM/TO instructions.

•Install the FX2NC-4AD on the right side of the main unit, extension block or special function block of the FX2NC Series PLC.

•DIN rail installation

The FX2NC-4AD can be installed on DIN rail DIN46277 (width: 35mm (1.38")). When removing the FX2NC-4AD, push downward on the DIN rail attachment hook.

For further details, refer to the Handy Manual packed together with on the PLC main unit.

Then push the slide lock downward to fix the FX2NC-4AD. When connecting two or more FX2NC-4AD units, connect an FX2NC-4AD unit to another FX2NC-4AD unit in the same way.

Up to four special function blocks or special function units in total can be connected to the FX2NC Series PLC including those connected to the FX2NC- CNV-IF.

For each connected special function block or special function unit, a unit number is assigned starting with 0 for the special function block and special function unit nearest to the main unit.

From the main unit, use FROM/TO instructions to read or write data stored in the FX2NC-4AD.

4.Wiring

4.1 Power supply wiring

Supply power (24V DC) to the FX2NC-4AD from the power supply connector. When using the power supply connector, the following power cables are available.
