Safety Switches and Controller
|
|
Carlo Gavazzi's range of safety modules includes modules for light curtains, safety mats, two hand control (anti-tie down devices), magnetic and safety switches and emergency stops. They are suitable for use in applications up to Performance Level "e" and Safety Integrity Level SIL 3. We also offer extension units which can be used to increase the number of safety outputs. Our safety modules are cUL and TUV approved. Our modules are powered by 24 VAC/DC and feature LED status indicators.

|
Multifunction Module Delayed Outputs
• The device can be connected with different types of input: E-stop, E-gate, limit switch, non-contact switch, safety light curtains (ESPE Type 4, Type 2), safety light beam (single beam), safety mat
• 2 x OSSD direct +2 x OSSD delayed
• Selectable delay time. Can be easily set-up through the hex-switch, from 0 to 30 sec.
|
Multifunction Modules Instantaneous Outputs
• The device can be connected with different types of input: E-stop, E-gate, limit switch, non-contact switch, safety light curtains (ESPE Type 4, Type 2), safety light beam (single beam), safety mat
• 3 x OSSD (NO) + 1 OSSD Auxiliary (1 NC) (CM30D1A) or 4 x OSSD (NO) (CM40D0A)
• 4 LEDs on the front panel indicate the status and any errors during operation
