New Interlock Switch Control Unit Monitors One or Two Read-Heads for Category Four Safety System



FREMONT, CA - Scientific Technologies, Inc. introduces the new EC-S2 Control Unit to its EC family of electrically coded interlock switches and control units. The EC-S2 individually monitors one or two read heads to provide a category 4 system. The unit may be combined with an EC-S4 Control Unit to guard applications with up to six doors while continuing to satisfy category 4 requirements according to EN954-1. These units are CE marked, BG approved, and UL and C-UL listed.

A monitored feedback loop allows the unit to function as a safety monitoring relay, and 6A/24VDC switching capability allows connection directly to power contactors. The EC Series provides a uniquely coded actuator with each switch to make it a highly tamper-resistant system ideal for use on sliding or swinging guard doors where high levels of vibration or misalignment up to 0.5 in. are expected. They are approved for use in Class I, Div. 2 gas and dust applications.
