CJ1W-AD042 Analog Input Unit
Analog Input Units CJ1W-AD042
Unit type: CJ-series Special I/O Unit
Isolation *1: Between I/O and Controller signals: Digital isolator (No isolation between I/O signals.)
External terminals: 18-point detachable terminal block (M3 screws)
Power consumption: 520 mA max. at 5 VDC
Dimensions (mm): 31 × 90 × 65 mm (W × H × D)
Weight: 150 g max.
General specifications: Conforms to general specifications for CJ Series.
Number of analog inputs: 4
Input signal range *2: 1 to 5 V, 0 to 10 V, - 5 to 5 V, - 10 to 10 V, 4 to 20 mA, *4
Maximum rated input
(for 1 point) *5: Voltage Input: ± 15 V, Current Input: ± 30 mA
Input impedance: Voltage Input: 1 MO min. Current Input: 250 O (rated value)
Converted output data: 16-bit binary data
Accuracy *7: 25 °C *8: Voltage Input: ± 0.2% of F.S. Current Input: ± 0.4% of F.S.
0 °C to 55 °C: Voltage Input: ± 0.4% of F.S. Current Input: ± 0.6% of F.S.
A/D conversion period *9 : 20 µs/1 point, 25 µs/2 points, 30 µs/3 points, 35 µs/4 points
Mean value processing: Stores the last "n" data conversions in the buffer, and stores the mean value of the conversion values. Buffer number: n = 2, 4, 8, 16, 32,
64, 128, 256, 512
Peak value holding: Stores the maximum conversion value while the Peak Value Hold Bit is ON.
Scaling : Setting values in any specified unit within a range of ±32,000 as the upper and lower limits allows A/D conversion to be executed and analog signals to
be output with these values as full scale.
Input disconnection detection: Detects the disconnection and turns ON the Disconnection Detection Flag. *10
Direct conversion : A/D conversion is performed and the converted value is refreshed when the ANALOG INPUT
DIRECT CONVERSION instruction (AIDC) is executed.
This instruction is supported by the CJ2H-CPU(-EIP) CPU Units with unit version 1.1 or later, and CJ2M-CPU.
CJ1, NJ501, and CP1H CPU Units and NSJ Controllers do not support direct conversion
