Interlock Switches Non contact Switches Sipha Control Units Specifications (continued) Safety Inputs Sipha 1 1 N.C. & 1 N.O. Sipha 2 & 6 6 x (1 N.C. & 1 N.O.) Maximum Input Resistance Terminals 1 – 4 200Ω Terminals 2 – 3 150Ω Minimum Approach Speed 17mm/s (0.67in/s) Safety Outputs Sipha 1 1 N.O. Sipha 1 2 N.O. Sipha 6 2 N.O. + 1 N.O. Delayed (0.6 to 30sec) Output Rating B300, AC-15, 4A/250V AC P300, DC-15, 2A/30V DC Minimum Switched Current/ Voltage 10mA/10V 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. Maximum Recommended Output Fuse 5A quick blow AC, 3A quick blow DC 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. Auxiliary Output Switching Capability Sipha 1 100mA/230V AC, 100mA/24V DC Sipha 2 & 6 2A/230 V AC, 2A/24 V DC Description Auxiliary Outputs (not for safety use) Sipha 1 1 N.C. Photovoltaic MOSFET (on resistance typically 36Ω) Sipha 2 & 6 1 N.C.
