3 SPECIFICATIONS

1: Accuracy of offset/gain setting at ambient temperature

Q62DA-FG needs to be powered on 30 minutes prior to operation for compliance to the specification (accuracy).

2: Accuracy per temperature change of 1 °C

Example: Accuracy when temperature changes from 25 to 30 °C

0.1% (Reference accuracy) + 0.008%/ °C (temperature coefficient)

5 °C (temperature change difference) = 0.14%

3: The following indicates the external load resistance when output current is 20mA or more.

3.1.2 I/O conversion characteristics

I/O conversion characteristics are used for converting the digital value written from the

PLC CPU to an analog output value (voltage or current output), and represented by

inclined straight lines when offset and gain values are included.

Offset value

The offset value becomes the analog output value (voltage or current) when the digital

input value set from the PLC CPU is 0.

Gain value

The gain value denotes the analog output value (voltage or current) when the digital

input value set from the PLC CPU is

12000 (when 1 to 5V, 0 to 5V, 4 to 20 mA, 0 to 20 mA or the user range setting1 to 3 is

selected),

16000 (when -10 to 10V is selected).
