• Manufacturer: Omron

Specifications of CS1W-SCU31-V1

• Lead Free Status / Rohs Status: Lead free / RoHS Compliant

Restrictions on Unit Placement
Always connect the HFU on the left side of the Basic Unit.
■ Insulation Blocks
Each EJ1 Unit is electrically insulated for each function block as shown in the following figures.
Functional insulation is applied between the power supply, input, output, and communications terminal sections.
If reinforced double insulation is required, use power supplies that comply with IEC60664 for reinforced double insulation for the EJ1's external
power supply and for power supplies connected to the EJ1.
■ Programless Communications
Communications with PLCs from OMRON (SYSMAC CS/CJ/CP Series) and Mitsubishi Electric (MELSEC-Q/QnA/QnAS/An/Ans/FX
be performed without creating ladder programming.
Using programless communications enables monitoring and changing settings for the EJ1 by simply reading and writing to PLC memory.
The EJ1 automatically performs communications with the PLC, which reduces work hours spent programming for communications from the PLC
to the EJ1.
