• Keep pulse converters separated for 10mm or more from each other.

10mm or more

If this installation cannot be

avoided, shorten the length of

the wiring with the host

controller as much as possible.

[4] Pulse Converter : JM-08

The pulse converter converts feedback pulses in the differential mode into those in the open

collector mode.

Use this converter in the case the pulse input of the host controller is open collector (24V)

type.

Host Controller

(PLC etc.)

SCON-CA

Caution:

1) Pay attention not to insert wrongly because it is the same e-CON connector as input and output.

Putting the power on with the insertion being wrong will burn JM-08.

2) Use the pulse converter in the ambient temperature range between 0ºC and 40ºC.

3) The temperature increase of about 30ºC occurs during operation. Accordingly, neither install

several pulse converters in close contact nor install them within a duct. Do not install the pulse

converter near other heating devices.

4) If more than one pulse converters are installed, set a pulse converter apart from another by 10mm or

more.

5) Make the wiring between the host controller (PLC, etc.) and JM-08 as short as possible. Long one is

easy to pick the noise. Also make the wiring between JM-08 to SCON controller as short as possible.

Place JM-08 close to the host controller.

A recommended installation sample is shown in the figure below.

• Make the cable length between the host controller and pulse converter as short as possible.

Wiring length :

50mm or shorter recommended
