Triconex PS4144110 Schneider Electric Power Supply Module

Models 3502E, 3503E, and 3505E can perform a self-test to detect a “stuck-open” condition

in which the circuitry is unable to determine whether a point has entered a shutdown state.

The ability to detect the point of shutdown is an important feature

since most security systems have a power failure trip feature.

In order to detect the presence of a “stuck-open” input,

the switch within the input circuit needs to be turned off in order for the opto-isolated

circuit to read a zero input (“off”).

The I/O communications processor will freeze the last reading while the test is running.

All TMR digital input modules support the hot standby feature and require a separate

external termination panel (ETP) with cable connections to the Tricon backplane.

Each module is mechanically keyed to prevent improper installation in the configured chassis.

Each TCM contains two network ports - NET 1 and NET 2. Models 4351A and 4353 have

two copper Ethernet (802.3) ports and Models 4352A and 4354 have two fiber optic Ethernet ports.

NET 1 and NET 2 support TCP/IP, Modbus TCP/IP Slave/Master, TSAA, TriStation,

The NET 1 also supports the Peer-to-Peer and Peer-to-Peer Time Synchronization protocols.

A single Tricon system supports up to four TCMs, which must reside in two logical slots.

Different TCM models cannot be mixed in a logical slot.

Each Tricon system supports a total of 32 Modbus masters or slaves, including network and serial ports.

The hot standby feature does not apply to TCMs, but you can replace a defective

TCM while the controller is online.

The EcoStruxure Triconex Safety Intelligent Enclosure (SIE) provides

an integrated solution designed to be mounted close to field instrumentation to reduce cabling

The SIE includes Tricon™ CX Universal Input/Output (UIO) modules, power supplies,

and External Termination Panels (ETPs) that are pre-installed and tested,

and can be connected to a wide range of field devices.
