Page 16: Precautions
PRECAUTIONS This section provides general precautions for using the Programmable Controller (PLC) and Analog I/O Units. The information contained in this section is important for the safe and reliable application of the Analog I/O Unit. You must read this section and understand the information contained before attempting to set up or operate a PLC system and Analog I/O Unit.
Page 17: Intended Audience
It is extremely important that a PLC and all PLC Units be used for the speci- fied purpose and under the specified conditions, especially in applications that can directly or indirectly affect human life. You must consult with your OMRON representative before applying a PLC System to the above-mentioned appli- cations.
Page 18: Operating Environment Precautions
Operating Environment Precautions • The PLC outputs may remain ON or OFF due to deposition or burning of the output relays or destruction of the output transistors. As a counter- measure for such problems, external safety measures must be provided to ensure safety in the system.
Page 19: Application Precautions
Application Precautions Application Precautions Observe the following precautions when using the PLC. !WARNING Always heed these precautions. Failure to abide by the following precautions could lead to serious or possibly fatal injury. • Always connect to a class-3 ground (to 100 Ω or less) when installing the Units.
Page 20: Ec Directives
EC Directives • Remove the labels after the completion of wiring to ensure proper heat dissipation. Leaving the label attached may result in malfunction. • Do not pull on cables and cords and do not bend them past their natural bending radius.
Page 21: Other Applicable Directives
EMC and Low Voltage Directives EMC Directive In order that OMRON products can be used with any machinery and in combi- nation with other manufacturer’s equipment, the products themselves are designed to comply with EMC standards (see note 1.), so that the assembled machinery or device can then also easily comply with EMC standards.
Page 22: Changes To The Cj1W-Da08V/08C And Cj1W-Mad42
Switching was changed by means of a DIP switch setting on the rear panel of the Unit. (CJ1W-DA08V/DA08C/ (With CJ1W/CS1W-AD041-V1/08-V1 Units, the operation mode can be MAD42) changed by means of either a rear-panel switch or a DM Area setting.) With the CJ1W-DA08V/DA08C/MAD42, it is possible only by means of a set- ting in D(m+18) in the Special I/O Unit DM Area.
Page 23 Changes to the CJ1W-DA08V/08C and CJ1W-MAD42 For earlier models, the maximum value was 12 mA (for 1 k Ω of external load External Maximum Output Current during resistance). For the CJ1W-DA08V/MAD42, the maximum value is 2.4 mA (for 5 k Ω of external load resistance). Voltage Output (CJ1W-DA08V/MAD42) For earlier models, the maximum value was 600 Ω.

Page 389 Appendix B Sample Programs Scaling Using the Scaling Functions Note This function is supported only by the CS1W-AD161, CJ1W-MAD42, and CJ1W-DA08V/08C. Outline A pressure sensor is connected to analog input 1 of CJ1W-MAD42. The pressure sensor outputs an analog signal of between 0 and 20 mA for a pressure between 0 and 500 Pa. Therefore, for a 4 to 20-mA input, a binary value of 0000 to 01F4 (0 to 500 decimal) in engineering units for the pressure in Pa is directly set using the MOV instruction.
