TSXDST1682 - Output Module - TELEMECANIQUE

Discrete I/O modules provide the functions of matching, galvanic isolation, filtering and protection against induced interference, overloads and overvoltages.

Characteristics specific to this range of modules are :

- Hardware location device
These devices are fitted to all the modules as well as to the backplane of the rack. By enabling the user to customize each slot of the rack to receive a particular type of module, this device eliminates all risks of errors when inserting or exchanging a module. A second location device allows the user to distinguish between modules of the same type but which may have different uses or are adjusted differently.
- Software location device
During the configuration procedure, the software code for each module is assigned to the specific slot it must occupy. If the actual configuration does not agree with that declared, the processor is informed.

The exchange of data between the PLC processor and the I/O modules is systematically checked during each PLC scan.
- Hardware security
The design of the I/O bus, incorporating high level technology, complete screening and withstand to short circuits, ensures a high level of security for data exchanged over the I/O bus.
- Software security During each data exchange, the processor checks (parity check) the validity of data carried on the bus. In case of error, the processor does not validate the exchange and a fault is declared. This procedure avoids disrupting the control system due to incorrect exchanges.

TSX DET 4 66 Namur input module. This has 4 inputs specially designed for receiving signals from Namur proximity sensors. Volt-free contacts can also be connected to this module. Each input has a line monitoring device which detects line breaks and short-circuits.

TSX DST 4 17 output module. This has four a 24/48 V - 2 A outputs which are isolated and electronically protected against overloads and short-circuits. If any of these outputs goes to 1 when the external supply is absent, a fault bit is detected.
One fault lamp per point indicates that a fault is present. One fault bit per point is then transmitted to the PLC processor.

TSX DET 32.., TSX DST 24 72 and TSX DST 32 92 modules
24 and 32-point discrete I/O modules can be combined to create configurations of 224 I/O in a single format rack (128 inputs in 32-point modules and 96 outputs in 24-point modules) or of 256 I/O (128 inputs in 32-point modules and 128 outputs in 32-point modules).
The terminal block fault bit (accessible by programming terminals or the application program) indicates the absence or incorrect voltage of the sensor (or preactuator) supply at the module.
