can be mounted on VJCE.
● Different signal conditioners of VJ series can be mixed and housed in the same mounting base.
● Signal condition of input/output is selectable out of 4 types.
The VJCE can be installed horizontally on 19 inches rack complies with JIS/EIA standards, or horizontally on the
wall. Under the conditions mentioned in Article 3.2, a maximum of 5 mounting bases can be installed on one side of
the cabinet.

(3) In case storing in cabinet, air cooling is
compulsorily required to prevent from raise of
temperature.
(4) Do not install it on the heating materials.
(5) In case of installing the VJCE one above
another to up and down direction, take
installation space as shown in the figure on the

NOTE
Insert and pull out the signal conditioner vertically to VJCE.
Inserting and pulling it out slantwise may make the pin bent and
cause a failure such as a bad contact.
4.1Field Side Wiring and Wiring of Power Supply and Ground
Flexible twisted cable and good contact of durable round crimp-on terminals are recommended to use.

4.2Field Side Input/Output Terminals, Piping and System Side Wiring
Assignment of Input/Output Terminals on and after page 7 shows relation between VJCE field side input/output terminals and signal conditioner input /output signal at the terminals. (Refer to the assignment for the model code to be
used for wiring.) Field side input/output terminals are M3.5 screws. Exclusive cable is used for connection between
VJCE and VM1, PM1 cards. Connect input air pressure signal of VJF1 to connecting hole of front face of signal conditioner directly. Connect power and ground cables to power terminals of VJCE. Power would internally be distributed
to respective signal conditioners.
WARNING
It is recommended that CT protector (CTG-5) be attached to the current input terminals connected to the
secondary side of the CT when mouning VJB1 (CT transmitter) on VJCE. Since a high potential
develops over the secondary side, the CT may burn and break if you unplug the VJB1 from the VJCE
while the VJB1 is turned on and it has no CT protector.
IMPORTANT
●
Ensure the followings before turning on the power. Use of signal conditioners of VJ series ignoring
the specifications may cause overheating or damage to VJCE-01A and signal conditioners.
·Power supply voltage and input signal value applied to VJCE-01A and signal conditioners should
meet the required specifications.
·The external wiring to the terminals is as specifications.
●
Do not operate the product in the presece of flammable or explosive gases or vapors. To do so is
highly dangerous.
●
Many semi-conductor integrated circuit parts are used for signal conditioners. Take care of static
electricity trouble at the maintenance or change of setting for the signal conditioners.
●
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 of the product to the ground. Do not carry out daisy-chained inter-ground terminal wiring.
*1: For 2-channel type of VJC1 and VJA4, only the voltage output can be mounted on VJCE. Output of channel-1 is output to the connector (CN1).
*2: Since VJQ2 is single output type, output-2 terminals are N.C.
*3: When receiving current input (current pulse), external shunt resistor (receiving resistor) is required.
