Product Details

T3481A Features

Sixteen Guarded outputs (in two groups of eight).

Fault tolerant operation when connected in parallel with another module of the same type.

Hot-replaceable.

Complete, automatic testing of all output circuits.

Automatic line monitoring detects open and short field wiring circuits.

Individual front panel indicators on each module show module fault/active status and shutdown state; additional indicators show output status and load/fuse fault for each point.

Fuses accessible from front panel.

2500 minimum electrical isolation between field and logic circuits.

The processor modules send triplicated write data commands over the I/O Safetybus to the monitored Guarded output module. Onboard the output module the triplicated data are routed to two independent voters which provide voted data to associated field programmable gate arrays (FPGA). Each FPGA independently operates one of the two output control switches. The two output switches are connected in series with the load.

When both output switches are on, current will flow through the output and energize a field load. If either switch is off, current will not flow through the output and the load will be de-energized. This combination of series output switches and independent drive signals produces fail-safe activation of the load. Single failures can only affect one of the output drive signals or switches.

Moore News

Hydropower industry with power industry capabilities.
The working power of the remote I/O is provided by the corresponding LCU to the unit local control unit (LCU1, LCU2, LCU3, LCU4).
The LCU should provide an RS-485 serial interface, using the Modbus (Master and Slave) standard communication protocol interface.
Molex is used for gateway protocol conversion. The module is directly plugged into AB's 1756 rack and has standard blocks for programming.
The international standard industrial Ethernet protocol EtherNet/IP is used between the PLC and the workstation in the LCU.
The communication speed reaches 100Mbps, and the PLC adopts AB ControlLogix system governor oil pump control loop and ball valve control loop to enter the unit's local LCU control.

Thermal power industry with power industry capabilities: With the development of society, network technology, computer technology and PLC control technology are becoming more and more mature. All auxiliary control systems of thermal power plants can enter the whole plant auxiliary network control system to realize complete monitoring operation in the centralized control room.The level of automation has been greatly improved, and the efficiency of the whole plant has been improved.
