LT Programmable Controller
The LT Range is a line of modular controllers for tough military and industrial environments.
The military version features enhancements that support the use in a harsher environment and contribute to cybersecurity.
Each module is integrated in aluminum sleeve which simultaneously ensures
- Immunity to electromagnetic interference
- High mechanical strength
- IP protection (NF EN 60529)
- Good heat dissipation
Length of the base : from 4 to 30 modules.
Input/output connectors : screw terminals/spring cage (industrial version) or connectors SubD (military version) .
Mounting : DIN rail, grid or on the amounts of the cabinet with brackets.
Installation : box or cabinet.
- Digital inputs : 16/32/48/64 channels boards

Wiring control digital input
The wiring control digital inputs are designed for monitoring sensitive sites and the anti-intrusion control of critical installations.
The input is used to detect the 4 states of a line between the sensor and the input of the automaton: sensor Normally Open, Normally Closed, Short Circuit on the line or line cutted.
The detection resistors installed near the sensor can be chosen between 1kΩ and 10kΩ.
The PLC provides 1 status bit and 1 defect bit to encode the 4 states.
The distance between the sensor and the PLC input can be up to 200m.
