TB400 Signal Switcher

image

Improving the troublesome connector unplugging and plugging operations involved in parallel running, leading to a significant reduction in man-hours.

  • Switching the control output signal from either of two systems.
  • Switching systems with the manual switch or external contact signals.
  • Improving the troublesome connector unplugging and plugging operations involved in parallel running, leading to a significant reduction in man-hours.
  • Automatically switched to system-A side with the power off. Continuous production is possible without the need of unplugging and plugging the connector for parallel running.

*1 Products are warranted for years from the date of shipment.

Warranty Period *1 3Years
Standard Lead Time Custom Products
Power Supply 24V DC
Connection MIL connector (OMRON: XG4A-2034)

TB401 Signal Distributor

image

Improving the troublesome connector unplugging and plugging operations involved in parallel running, leading to a significant reduction in man-hours.

  • Distributing the contact signal from the field to two systems (system A and system B) in parallel.
  • Switching systems with the manual switch or external contact signals.
  • Supporting external power supply (contact voltage) of 48V DC.
  • Maintaining connection to system A after parallel running.

TB400

DO signal: 16 ch/card × 2; total 32 ch
RO (relay output signal): 8 ch/card × 2; total 16 ch
AO (analog output signal): 16 ch/card × 2; total 32 ch
Switching the control output signal from either of two systems to the field.

The unit is designed such that the system switches to system-A side whenever the power is off. Keeping the existing system connected to the system-A side for parallel running allows production to be continued without unplugging and plugging the connector. (After the completion of parallel running, the new system connected to system-B side must be reconnected to the system-A side.)

image

Parallel running of existing and new systems involves manual unplugging and plugging of the connector for every switching, requiring a lot of man-hours and therefore hindering efficient work.

image

When you install the TB400, you can easily switch signals without unplugging and plugging the connectors.
The connecting cables are flat, so you can do wiring work efficiently.

image

You can switch signals not only by the switch but remotely with external contact input. Therefore, you can perform your work more efficiently.

TB401

DO signal: 16 ch/card × 2; total 32 ch
Distributing the contact signal from the field to two systems (system A and system B) in parallel.

Mounting a non-conditioning I/O adapter (optional) "TH401-□" on the PCB inside the card allows connection to system A to be maintained even when system B (existing) is disconnected after parallel running (assuming that the PLC (DCS) should be connected only to system A).

image

The TB401 also supports 48V DC DI signal.
Since the voltage to the output (PLC) side is always 24V DC, you can use the existing 48V DC sensor without any change.

image

You don't have to prepare a new terminal block.
You can use the existing one as it is. When you connect it to the TB401, the unit will distribute signal to two systems, system A and system B.

image

You can switch signals not only by the switch but remotely with external contact input.
Therefore, you can perform your work more efficiently.
