Event output (Option code: A5)
Event output, EVT4 and EVT5 can be added.
Output will be turned ON or OFF depending on the conditions selected from [Event
output allocation].
Output: Relay contact, 1a
Control capacity: 3 A 250 V AC (Resistive load)
1 A 250 V AC (Inductive load, cos =0.4)
Electrical life: 100,000 cycles
Serial communication (Option code: C, C5)
This option and Console communication cannot be used together.
The following operations can be carried out from an external computer.
(1) Reading and setting of the SV, PID values and various set values
(2) Reading of the PV and action status (3) Function change
Cable length:
Max.15 m (C)
Max.1.2 km (C5)
Cable resistance: Within 50
(Terminators are not necessary, but if used, use a terminator
of 120 minimum on both sides.)
Communication line:
EIA RS-232C (C)
EIA RS-485 (C5)
Communication method: Half-duplex communication
Synchronization method: Start-stop synchronization
Communication speed: 9600/19200/38400 bps (Selectable by keypad)
(Factory default: 9600 bps)
Data bit/Parity:
7 bits, 8 bits/Even, Odd and No parity (Selectable by keypad)
(Factory default: 7 bits/Even)
Stop bit:
1, 2 (Selectable by keypad) (Factory default: 1)
Communication protocol: Shinko protocol/MODBUS ASCII/MODBUS RTU
Selectable by keypad
(Factory default: Shinko protocol)

Number of connectable units: 1 unit to 1 host computer (C)
Maximum 31 units to 1 host computer (C5)
Communication error detection: Parity, checksum (Shinko protocol), LRC (MODBUS
ASCII), CRC-16 (MODBUS RTU)
Digital external setting: Receives Step SV from Shinko programmable controllers PCA1
or PCB1 (‘SV digital transmission’ should be selected in [Communication protocol]).
If data from the PCA1 or PCB1 is higher than the SV high limit or lower than SV
low limit value, this instrument ignores the value, and controls at SV high limit or
SV low limit value.
SV adds Step SV to SVTC bias value.
