GT1-TS04P

What type of industrial module is this?

It is a four-channel temperature input unit designed for Omron GT1 Multiple I/O Terminal systems. It converts resistance temperature detector signals into temperature data that can be processed by a connected PLC through the network communications unit.

Which temperature sensors are compatible with this unit?

The unit accepts Pt100 and JPt100 resistance temperature detectors. The connected sensor type and configuration must match the unit settings and wiring arrangement.

How many temperature inputs does the unit provide?

The GT1-TS04P provides four temperature input channels, allowing up to four compatible RTD sensors to be monitored from one unit.

How much PLC memory does the unit use?

It occupies four input words in its standard operating mode or eight input words when the relevant expanded mode is selected. The chosen allocation must be reflected in the PLC and network configuration.

How does the unit connect to a PLC network?

It connects through the GT1 I/O unit interface to a compatible Omron communications unit. In a DeviceNet installation, the communications unit exchanges the temperature data with the network master.

What power supply does the unit require?

The temperature input unit is intended for a nominal 24 VDC external power supply. The supply voltage, polarity and wiring should be checked against the system specification before energising the equipment.

How is the unit installed?

It is designed for mounting on a 35 mm DIN rail inside an appropriate control panel. It should be installed in the specified orientation and secured firmly to the rail.

What type of field wiring connection is provided?

The unit uses an M3 screw terminal block for its temperature inputs and associated field wiring. Terminal screws should be tightened evenly within the specified torque range.

Can it be connected directly to thermocouples?

No. The GT1-TS04P is intended for Pt100 and JPt100 RTD inputs. Applications using thermocouples require the corresponding GT1 temperature input variant designed for thermocouple signals.

What do the front indicators show?

The TS indicator shows the condition of communication across the GT1 I/O unit interface. The PWR indicator confirms the presence of operating power, while the U.ERR indicator identifies an error within the temperature input unit.

How many I/O units can be connected to one communications unit?

A compatible GT1 communications unit can accommodate up to eight I/O units. The total current consumption, I/O allocation and network arrangement must remain within the system limits.

What should be checked if no temperature value is being received?

Check the 24 VDC supply, RTD wiring, sensor type selection, terminal connections, I/O interface cable and end connector. The TS, PWR and U.ERR indicators can also help identify whether the issue concerns power, configuration or unit communication.

Can the internal cassette be replaced separately?

Yes. This model is designed with a replaceable cassette. All relevant power supplies must be switched off before removing or fitting the cassette, and the replacement must be inserted in the correct orientation.

What environmental conditions should be avoided?

Avoid locations exposed to condensation, corrosive or flammable gases, excessive dust, salts, direct sunlight, strong vibration, shock, water, oil or chemicals. The unit should also be separated from high-voltage and high-current wiring to reduce electrical interference.
