Shielded wire
Connect only one end of the shielded wire to the FG terminal so that current cannot flow to the
shielded wire. If both ends of the shielded wire are connected to the FG terminal, the circuit will be
closed between the shielded wire and the ground. As a result, current will run through the shielded
wire and this may cause noise.
Be sure to ground FG terminal.
Recommended cable: OTSC-VB 2PX0.5SQ (made by Onamba Co., Ltd.) or equivalent (Use a twisted
pair cable.)
(2) Set value digital transmission
By connecting to Shinko programmable controllers [PC-900 or PCD-33A with the SVTC (Set value
digital transmission) option], digital SV via the SVTC command can be received from programmable
controllers.
Wiring
For the PC-900, connect YA (-) to YA (-), YB (+) to YB (+), COM to SG terminal respectively.
For the PCD-33A, connect YA (-) to YA (-), YB (+) to YB (+), SG to SG terminal respectively.
Up to 31 units of the BCS2 or BCR2 or BCD2 can be connected.
The following shows a connection example of PCD-33A and BCS2, BCR2, BCD2. (Fig. 4.4.7-3)
