1.Introduction

The FX2NC-4DA analog output block (hereafter referred to as "FX2NC-4DA") converts 4 digital values (from the PLC main unit) into analog output values (voltage or current).

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

1)Each analog output channel can be configured for voltage output, or current output. The output mode must be set using the TO instruction and the appropriate connection method.

A different analog output can be selected for each channel.

2)The voltage output ranges from -10 to 10 V. The current output ranges from 4 to 20 mA and from 0 to 20 mA. The output characteristics can be adjusted for each channel.

3)The resolution is 5 mV (10 V ⋅ 1/2000) when the voltage output is used, 20 ∝A (20 mA ⋅ 1/1000) when the current output is used.

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

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

•DIN rail installation

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

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

Then, push the slide lock downward to fix the FX2NC-4DA. When connecting two or more FX2NC-4DA units, connect an FX2NC-4DA unit to another FX2NC-4DA 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, the 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 the FROM/TO instructions to read or write data stored in the FX2NC-4DA.

4.Wiring

4.1 Power supply wiring

Supply power (24V DC) to the FX2NC-4DA to either the power supply connector or the power supply terminal.

When using the power supply connector, the following power cables are available.
