Warning Indications Do not touch or approach the product while or immediately after power is supplied. Electric shock or burn injuries may occur. Never disassemble, modify, or repair the product or touch any of the internal parts. Minor electric shock, fire, or malfunction may occasionally occur. Do not use the product in an environment where flammable or explosive gas is present. Relay life expectancy varies considerably with output load and switching conditions. Always consider the application conditions and use within the rated load and electrical life expectancy. • Do not use the product...

How to mount on rail Follow the procedures below to mount the product on the rail or remove it from the rail. (1) Tilt the product about 10° with respect to the rail. Engage the hook at the power supply side and gently push the product down. (2) Press the product against the rail. (3) Lift the product up to engage the hook at the load side with the rail. (4) Gently jiggle the product to check that the load-side hook is engaged with the rail. Removing from rail (1) Hold the product at the top and bottom. Push it downward to release the lower hook. Mounting angle Installation interval Mount with...

(2) Insert the recommended tool straight at about 10angle in the direction of the arrow, into the terminal block until the end touches the release hole. (3) With the tool inserted in the release hole, insert straight in until the wire contacts the...

Recommended Ferrules and Crimp Tools Recommended ferrules * OMRON's exclusive purchase model XW4Z-00B is available to order as SZF 0-0,4*2,5 (manufactured by Phoenix Contact). Recommended flat-bladed screwdriver (Recommended tool) Use a flat-blade screwdriver to connect and remove wires. Use the flat-blade screwdriver shown in the table below. The following table shows manufacturers and models as of 2018/Dec. Voltage fluctuation range and voltage drop in control circuit • AC-operated (J7KCA-D-ACD) Must operate voltage: 85% to 110% of rated voltage However, this is the rated voltage for making....

The control coil of AC-operated does not contain a built-in surge absorber. Use an optional coil surge absorption unit if required. The control coil of DC-operated contains a built-in surge absorber (varistor). Therefore, it is not necessary to connect an external surge absorption circuit in a normal sequence circuit. (See Table 1) Connect the control coil terminals and various DC output devices as shown in Table 2. Note that the control coil terminals have A1 (plus) and A2 (minus) polarities. Table 1. Coil voltages and varistor voltages of DC-operated When the surge voltage reaches or exceeds...
