  • Plug connector M12
TX1B-A024SEM4AS1 (Order no. 094403)

Description

Guard locking type

TX1

Closed-circuit current principle, guard locking by spring force. Release by control of AS-i output 0.

Control of the guard locking solenoid

The guard locking solenoid is controlled by the control system via AS-Interface bus bit D0. In addition, the 24V connection can be switched safely.

AS-Interface inputs

D0, D1

Positively driven NC contact 1 (safety door monitor)

D2, D3

Positively driven NC contact 2 (guard lock monitoring)

Evaluation is performed via a safety monitor.

AS-Interface outputs

D1

LED red

D2

LED green

Internal LED function display

  • The Power LED indicates the operating voltage on the bus.
  • The Fault LED indicates if a fault has been detected on the AS-Interface bus.

External LED function display

  • The green and the red LEDs can be controlled as required by the control system via the bus using bits D1 and D2.

Auxiliary release

This is used for releasing the guard locking with the aid of a tool. To protect against tampering, the auxiliary release is sealed with sealing lacquer.
