Safety automation system solutions
Preventa safety module type TSX DPZ
Safety module TSX DPZ 10D2A provides the following functions:
b Monitoring of 1 to 4 dual (or single), N/C (normally closed) contacts in pushbuttons, Emergency stops or limit
switches on safety guards for an Emergency stop or immediate safety stop system (category 0 Emergency stop
conforming to EN 418).
b Hard-wired safety module identical to Preventa safety module XPS:
v 2 N/O safety output circuits,
v category 3.
b Safety module independent of the TSX Micro PLC processor: the PLC does not affect the safety module.
b 10 LEDs on the TSX Micro PLC display panel: power supply failure and full diagnostics of the safety system.
b Electronic data acquisition units for full diagnostics of the safety system:
v reading the state of the 8 pushbutton or limit switch inputs,
v reading the enable input and the feedback loop,
v reading the control signal of the 2 safety outputs,
v monitoring the external power supply for the module.
This electronic data acquisition is designed so that the first failure will not adversely affect the safety function.
If the safety system uses more sensors, it is possible to daisy-chain several TSX DPZ 10D2A modules.
To ensure correct operation of the safety function whatever the first failure, the following must be used :
b At the inputs: Emergency stop pushbuttons or safety limit switches with dual contacts.
b At the outputs: if relaying is required, use relays with guided contacts.
b Module power supply: use an F1 protection fuse (see characteristics on page 2/22).
1 Emergency stop or limit switch activated.
2 Emergency stop reset or limit switch closed.
3 Error on contact S0…S3.
