SF-CL1T264T

The SF-CL1T264T provides total solution to safety systems. It realizes networking light curtains and safety devices with reduced wiring.

Features

  • Connecting the I/O of light curtains and safety devices to the field network CC-Link Safety enables to transmit safety circuit signals collectively for network control.
  • Allows to readily connect up to two sets of series SF4B light curtains with connectors.
  • Programmed muting control of light curtains is also available where the line stops only when a human body is passing through the light curtain while it keeps running when a work piece is passing through.
  • Cables stay connected while detaching the terminal block, contributing to reducing maintenance man hours.

Notes:

1) Where measurement conditions have not been specified precisely, the conditions used were an ambient temperature +20 ℃ +68 ℉.

2) The power supply connected to this product must satisfy the following conditions:

1 SELV (Safety Extra Low Voltage) : Reinforced insulated from hazardous potential part (48 V or more)

2 Compliance with the LVD (Low Voltage Directive)

3 Output voltage within 21.6 V to 26.4 V DC (Ripple P-P: 10 % or less.)

3) Total number of input points is 8 points, and use 2 points for control output (OSSD 1, 2) of 2 light curtains. Two inputs terminals are assigned for each input since dual wiring is supported.
