Isolation Sensor Switch Push button in Amplification Solenoid Valve Actuator out Indicator Lamp Contactor PLC Small Motor External Interface Isolation to protect against external interference e.g. from unskilled personnel e.g. HVAC, water/waste water applications, small biogas systems, alternative energy applications Page 2 Update Relays and Opto Couplers – 2. Quarter 2010 – Susanne M. Walker Why Opto Couplers and Solid-State Relays? Used for Isolation and Amplification - Long lifetime and reliability Fast response time, no contact bounce No switching noise Unsusceptible to shock and vibration No electromagnetic radiation Low control power Optimized machine up time Long term cost savings Reliable but higher in initial component cost Page 3 Update Relays and Opto Couplers – 2.

Walker New TTL- Converter Page 5 MICROOPTO Solenoid Inductive Loads Switching of inductive loads - Pure resistive loads are rare in industrial environments - Through the stored coil energy inductive load switching causes high voltage- and current peaks during the switching cycle. - A reduction of the inductive peak switching energy can be achieved through protection circuits (e.g. diode, varistor….)

Quarter 2010 – Susanne M. Walker MICROOPTO Solenoid Application Ideal switching amplifier on the output side of control systems (generally 24VDC, 0,1...0,5A) to drive inductive loads like magnetic valves, contactors up to 24 V DC / 10A. The output will be short circuit and overload controlled. The external control system will get a feedback via a potential free alarm contact so that the machine can drive into a save status and the defect can be eliminated.

Quarter 2010 – Susanne M. Walker Advantage MICROOPTO Electronic CO Application Example signal inversion Electronic change over systems can be used anywhere, where outputs via control signals has to be commutated. The NC- contact of the change over system reverses the input signal, so that it can be used as an independent inverter. In comparison with electro-mechanic change over contacts electronic COs switch absolute wear free and thus enhance the equipment availability while switching high frequencies > 1 kHz.

Quarter 2010 – Susanne M. Walker MICROOPTO TTL Converter Application 5VTTL signal converters will be used to adapt low power static 5V TTL signals (e.g. from special printer interfaces or closed loop control systems) to the commonly used 24 VDC automation world. TTL signals are very sensitive. On this account the complete electronic has to be protected by galvanic separation. The TTL signal is not able to provide enough energy to supply the internal electronic. This will be achieved via an external auxiliary voltage. For this reason standard 5V optos can't be used in TTL application. Update Relays and Opto Couplers – 2. Quarter 2010 – Susanne M.
