EC Series Electrically Coded Interlock Switch and Control Unit

 
Check up to five results to perform an action.



  • The EC Series Control Units individually monitor one to four Read Heads to provide a Category 4 system for applications with up to four guard doors
  • Uniquely coded actuators provide a high level of tamper resistance
  • Misalignment of nearly 1/2 inch allows application on machine doors with a high level of vibration or alignment issues
  • Manual or automatic start is switch selectable
  • External Device Monitoring (EDM) allows the EC Series Control Unit to function as a safety monitoring relay
  • The 6 A/24 VDC switching capability of the Control Unit allows connection directly to power contactors
  • Individual guard door status may be monitored with the semiconductor outputs from the Control Unit; an additional output gives status of the Control Unit
  • Guarding applications with more than four doors may be achieved by combining two or more Control Units in series while continuing to satisfy Category 4 according to EN954-1
  • Approved for use in Class I, Div. 2 gas and dust applications
Description
    The EC Series consists of a uniquely coded actuator, a read head (switch), and a control unit capable of monitoring 1 to 4 read heads.
    The uniquely coded actuator is a device known as a transponder (transmitter and responder) while the read head is a device known as a transceiver (transmitter and receiver). The actuator (transponder) receives an electromagnetic field from the read head (transceiver), processes it and sends data signals back to the read head which are read by the control unit. The data signals received by the control unit must match the known data signals of the control unit in order to close the safety outputs of the control unit.
    Each actuator has a uniquely coded element within the actuator that can not be reprogrammed which makes the actuators secure against manipulation. The ‘Teach-In Operation’ is used to ‘teach’ the control unit the code of each of the 1 to 4 actuators that are to be used with the read heads connected to the control unit. No additional equipment is required to perform the teach-in operation and there is no limit to the number of teach-in operations that may be performed.
    The EC-S2 and EC-S4 control units provide EDM (External Device Monitoring, also called MPCE monitoring) and may be operated in manual or automatic start mode allowing the control unit to function as a safety monitoring relay. There are also 2 or 4 solid state outputs on the control unit for individual monitoring of the status of each read head plus an additional output for the monitoring of the status of the control unit.
    The EC-S1 switch is available with a wide variety of cable lengths to 25 meters or with an integral connector to accommodate a variety of application requirements.

Specifications are subject to change without notice.

Note: The safety contacts of the Omron STI switches are described as normally closed (N/C) i.e., with the guard closed, actuator in place, and the machine able to be started.
