This is a Class A instrument. In a domestic environment, this instrument may cause radio
interference, in which case the user may be required to take adequate measures.
This instrument is protected from electric shock by reinforced insulation. Provide reinforced
insulation between the wire for the input signal and the wires for instrument power supply,
source of power and loads.
Be sure to provide an appropriate surge control circuit respectively for the following:
- If input/output or signal lines within the building are longer than 30 meters.
- If input/output or signal lines leave the building, regardless the length.
 This instrument is designed for installation in an enclosed instrumentation panel. All
high-voltage connections such as power supply terminals must be enclosed in the
instrumentation panel to avoid electric shock by operating personnel.
 All precautions described in this manual should be taken to avoid damage to the instrument or
equipment.
 All wiring must be in accordance with local codes and regulations.
All wiring must be completed before power is turned on to prevent electric shock, instrument
failure, or incorrect action.
The power must be turned off before repairing work for input break and output failure including
replacement of sensor, contactor or SSR, and all wiring must be completed before power is
turned on again.
 To prevent instrument damage or failure, protect the power line and the input/output lines from
high currents with a protection device such as fuse, circuit breaker, etc.
Prevent metal fragments or lead wire scraps from falling inside instrument case to avoid
electric shock, fire or malfunction.
Tighten each terminal screw to the specified torque found in the manual to avoid electric shock,
fire or malfunction.
For proper operation of this instrument, provide adequate ventilation for heat dispensation.
Do not connect wires to unused terminals as this will interfere with proper operation of the

1.1 Features
The communication extension module Z-COM module has the following features:
The SRZ unit sets all of the data items via communication. Therefore before operation, it is necessary to set
value of each data item via communication.
 The Z-COM module is connected to an SRZ functional module* (hereafter called “functional module”)
for the purpose of performing programmable controller communication (hereafter called “PLC
communication”) or host communication. The Z-COM module cannot be used alone.
The combination of Z-COM module and functional module is called an SRZ unit.
* SRZ functional module: Temperature control module Z-TIO module (hereafter called the Z-TIO module)
Digital I/O module Z-DIO module (hereafter called the Z-DIO module)
SRZ unit
Z-COM module Z-TIO modules Z-DIO modules
• Host communication
SRZ unit interfaces with the host computer or the operation panel via Modbus or RKC
communication protocols.
(RS-422A and RS-485 communication interfaces are used for both protocols.)
• PLC communication
SRZ unit can be connected to the MITSUBISHI MELSEC series or OMRON SYSMAC series
programmable controller (hereafter called the PLC) without using any program.

 Number of temperature control
• Up to 16 Z-TIO modules can be connected to one Z-COM module. For example, when up to 16
Z-TIO modules (4-channel type) are connected to one Z-COM module, the maximum number of
temperature control channels per one unit becomes 64.
• For PLC communication, up to four Z-COM modules can be multi-drop connected to one PLC
communication port. Therefore, temperature control of up to 256 channels per one PLC
communication port can be performed.
• For host communication, up to 16 Z-COM modules can be multi-drop connected to one
communication port of host computer. Therefore, temperature control of up to 1024 channels per one
communication port of host computer can be performed.
