4-state logical inputs with wiring control.

Wired-Control Logical Inputs are designed for monitoring sensitive sites and intrusion detection of critical installations.

Wired-control inputs allow detection of the 4 states of a line between the sensor and the controller input:

  • Normally Open sensor, Normally Closed sensor, short-circuited line, or cut line.
  • The detection resistors installed near the sensor can be chosen between 1 kOhm and 10 kOhm.
  • The controller provides 1 status bit and 1 fault bit to code the 4 states.
  • The distance between the sensor and the controller input can reach up to 200 meters.

Relay logic outputs.

  • Free potential contacts.
  • Breaking capacity: 6A
  • More than 30 million operations
  • ON/OFF visualization via “orange” LED

Version for harsh environments.

Climatic and electromagnetic endurance.

  • Extended operating temperature: -40°C to +70°C
  • The boards are tropicalized.
  • Enhanced electromagnetic endurance to comply with the AECTP500 standard.

Mechanical endurance

  • The input/output connectors are screw-type SubD connectors.
  • The Ethernet RJ45 connectors are equipped with anti-vibration covers.
  • The mounting attachments are reinforced.

Software services to contribute to cybersecurity

  • SNMP V3 Protocol
