CAUTION
This product is intended for use with industrial machines, test and measuring equipment.
(It is not designed for use with medical equipment and nuclear energy.)
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
instrument.
Turn off the power supply before cleaning the instrument.
Do not use a volatile solvent such as paint thinner to clean the instrument. Deformation or
discoloration will occur. Use a soft, dry cloth to remove stains from the instrument.
To avoid damage to instrument display, do not rub with an abrasive material or push front
panel with a hard object.
Do not connect modular connectors to telephone line.

1. OUTLINE
1.1 Features
The module type controller has the following features:
The current transformer input module Z-CT (hereafter called Z-CT module) has 12 current transformer
(CT) inputs (hereafter called CT inputs), and is a functional module that is used exclusively for the module
type controller SRZ. Z-CT module interfaces with the host computer via Modbus or RKC communication
protocols. The Z-CT module sets all of the data items via communication (The communication interface
used for both protocols is RS-485). Therefore before operation, it is necessary to set value of each data item
via communication.
Heater break alarm (HBA) and heater overcurrent alarm are possible
A Z-TIO module or Z-DIO module can be connected to a Z-CT module to enable the use of heater break
alarm (HBA), heater melting alarm, and heater overcurrent alarm. (Time proportional output is supported.)
Both heater break alarm (HBA) and heater overcurrent alarm can be used with one CT input.
(Either alarm can also be used alone.)
• A Z-CT module can be connected to a Z-TIO module to enable heater break alarm (HBA) and heater
overcurrent alarm for three-phase loads.
• When the output distribution function is used with a Z-DIO module, a Z-CT module can be connected
to enable heater break alarm (HBA) and heater overcurrent alarm for distribution output.
Heater break alarm (HBA) and heater overcurrent can be set automatically
The heater break alarm (HBA) set value and heater overcurrent alarm set value can be automatically set
using the push button on the front of the Z-CT module or by communication.
CTs other than the specified CTs can also be used
CTs other than the specified CTs can be used by changing the CT type and CT ratio settings. There are
certain requirements for the CTs that can be used.
For details of CT condition, see on page 7-18.
Specified CTs
• CTL-6-P-Z (0.0 to 10.0 A)
• CTL-6-P-N (0.0 to 30.0 A)
• CTL-12-S56-10L-N (0.0 to 100.0 A)
12-point current measurement is possible with a single module
Up to 12 current transformers can be connected to one Z-CT module.
Up to 16 Z-CT modules can be connected, enabling 192-point current measurement.
When used for current measurement applications, a Z-CT module can be used by itself.
Some usage conditions may prevent the current transformer (CT) input value monitor
from showing the root mean squared current value. (See P. 7-4)

1.6 Application of Z-CT Module
For three-phase load alarm monitoring
For three-phase loads, two CT inputs are used for one control output.
When a Z-TIO module is connected to a three-phase load, the CT input (option) of the Z-TIO module does
not allow heater break alarms (HBA) and heater overcurrent alarms to be added to all control outputs.
A Z-CT module can be connected to the Z-TIO module to add heater break alarms (HBA) and heater
overcurrent alarms to the control outputs that could not be handled by the CT input (option) of the Z-TIO
module.

For CT input value monitor
One Z-CT module is capable of monitoring 12 channels of current.
When only used for CT input value monitoring, the Z-CT module can be used by itself; connection to
another SRZ functional module (Z-TIO or Z-DIO module) is not necessary.
Some usage conditions may prevent the current transformer (CT) input value monitor
from showing the root mean squared current value. (See P. 7-4)

4. WIRING
4.1 Wiring Cautions
To prevent electric shock or instrument failure, do not turn on the power until all
the wiring is completed.
WARNING
!
• To avoid noise induction, keep input/output signal wires away from instrument power line, load lines and
power lines of other electric equipment.
• If there is electrical noise in the vicinity of the instrument that could affect operation, use a noise filter.
− Shorten the distance between the twisted power supply wire pitches to achieve the most effective noise
reduction.
− Always install the noise filter on a grounded panel. Minimize the wiring distance between the noise
filter output and the instrument power supply terminals to achieve the most effective noise reduction.
− Do not connect fuses or switches to the noise filter output wiring as this will reduce the effectiveness of
the noise filter.
• Power supply wiring must be twisted and have a low voltage drop.
• For an instrument with 24 V power supply, supply power from a SELV circuit.
• A suitable power supply should be considered in the end-use equipment. The power supply must be in
compliance with a limited-energy circuits (maximum available current of 8 A).
• Supply the power to only one of the joined modules. When power is supplied to any one of the joined
modules, all of the joined modules will receive power.
• Select the power capacity which is appropriate for the total power consumption of all joined modules and
the initial current surge when the power is turned on.
Z-CT module power consumption (at maximum load): 35 mA max. (at 24 V DC)
Rush current: 10 A or less
• For the power supply terminals and communication terminals, use the specified solderless terminals.
Only these specified solderless terminals can be used due to the insulation between the terminals.
Screw Size: M3 × 7 (with 5.8 × 5.8 square washer)
Recommended tightening torque:

Connecting solderless terminals to CT input terminals (terminal type module)
When using a non-specified CT, use solderless terminals that are the same size as the above.
A spade terminal (Y type) can also be used if it is the same size.
