GENERAL

The VJP1 is a compact, plug-in pulse repeater that receives

contact, voltage or current pulse from a eld and converts them

into isolated transistor-contact pulses or contactless AC switch pulse.

Note

Insert/pull out the main unit into/from the socket vertically to the face of socket. Otherwise the terminals are bent and it may cause a bad contact.

1.1 Wall Mounting

Loosen the main unit-xing screw of the product and pull out the main unit from the socket. Fix the socket on the wall with screws. Next, insert the main unit into the socket and fasten the main unit with the main unit-xing screw.

1.2 DIN Rail Mounting

Insert a DIN rail into the upper part of the DIN rail groove on the rear of the socket, and then slide the slide lock at the lower part of

the socket upwards until the socket is xed into position as shown

below

2-M4 or 2-ø4.5 or more

Note When power of VJP1 is turned on/off, one pulse may be

counted by the pulse input device which connects to the VJP1.

Wiring should be connected to the terminals on the socket

of the product. The terminals for external connections are of

M3 screws. Use crimp-on terminal lugs for connections to the terminals.

• Recommended cables: A nominal cross-sectional area of

0.5 mm

or thicker for signal cables, and that of 1.25 mm2 or

thicker for power cables.

1.3 Mounting Using

When using a multi-mounting base, see the User's Manual for VJCE (VJCE Mounting Base).

1.4 Using a Duct

When using a wiring duct, install the duct at least 30 mm away from the top and bottom faces of the main unit.

2. INSTALLATION LOCATION

• Avoid the following environments for installation locations: Areas with vibration, corrosive gases, dust, water, oil, solvents,

direct sunlight, radiation, a strong electric eld, and/or a strong magnetic eld, altitude of more than 2000m above sea level.

• If there is any risk of a surge being induced into the power line and/or signal lines due to lightning or other factors, a dedicated lightning arrester should be used as protection for

both this converter and a eld-installed device.

• Operating temperature/humidity range: 0 to 50 C/5 to 90%RH (no condensation)

3. EXTERNAL WIRING

WARNING

Be sure to turn OFF the power supply before wiring to avoid the risk of electric shock. Use a tester or similar device to ensure that no power is being supplied to a cable to be connected.

Note

● Do not use output-2 for the single-output type.

● The power line and input/output signal lines should be installed away from noise-generating sources. Other wise accuracy cannot be guaranteed.

● The grounding resistance must be 100 Ω (JIS Class D grounding). The length and thickness of the grounding cable should be as short and thick as possible. Directly connect the lead from the ground terminal (terminal no. 8) of the product to the ground. Do not carry out daisy-chained inter-ground terminal wiring

● Use of the product ignoring the specications may cause overheating or damage. Before turning on the power, ensure the following:

Power supply voltage and input signal value applied to

the product should meet the required specications.

The external wiring to the terminals and wiring to ground

are as specications.

● Do not operate the product in the presence of

ammable or explosive gases or vapors. To do so is

highly dangerous.

● The product is sensitive to static electricity;

exercise care in operating it. Before you operate

the product, touch a nearby metal part to discharge static electricity.

● For 15-30 V DC (±20%) power supply, as a safety measure, always install a circuit breaker (an IEC 60947-compatible product, 1 A, 30 V DC) in an easily accessible location near the instrument. Moreover, provide indication that the switch is a device for turning off the power to the instrument.
