Description The ISIS-4 Safety Control Unit can monitor up to 4 ISIS safety switches. This easy to install, 35mm DIN Rail mounting housing provides 2 x safety and 1 x auxiliary output contacts (4A / 230V ac). Indicator LED’s in the ISIS-4 lid show the number of gates that have been selected, gate status, power and run.
A DIP switch located beneath the lid is used to select the number of active safety switches (note: The selector switch and number of safety switches must match or the control unit will not operate.) The coded magnetic safety switches provide a reliable, tamper resistant and cost effective method of monitoring machinery guarding where regular access is required. Approved by TUV to Category 3, the ISIS safety system is suitable for many applications including packing machinery and food processing environments. Approvals
