Description
With the increasing speed and complexity of applications a simple
magnetic switch may be insufficient to meet the increased risks,
therefore Sipha’s design incorporates several magnetically sensitive
elements which must be triggered in a particular sequence to operate
correctly. The Sipha sensor, designed to operate with its own
actuator, helps prevent defeatability by a simple magnet.
The control unit is available in three types. The Sipha 1 control unit
operates on 24V AC/DC and offers 1 N.O. safety output and 1 N.C.
solid state auxiliary output. The Sipha 2 control unit operates on
either 24V AC/DC, 110V AC or 230V AC and offers 2 N.O. safety
outputs and 1 N.C. auxiliary output. The Sipha 6 has wiring
terminals for up to 6 sensors, a delayed output for Category 1 stops
and offers the same wide range of power supply capability as the
Sipha 2 control unit. Between 2 and 6 Sipha sensors can be directly
connected to the Sipha 6 control unit. An internal DIP switch mutes
the unused connections to sensors 1, 2, 3 and 4. This allows for
individual monitoring to each interlock and provides enhanced
safety integrity when compared to six interlocks running off a single
Sipha 2 control unit.
The Sipha control units are designed to operate with the Sipha
sensors and actuators. The controllers have automatic reset.
