Richmond, VA – Weidmuller introduces the new Microopto line of solid state relays, designed specifically for the demands of industrial applications. Typical applications for the new optocouplers include driving 3-wire inductive actuators, such as solenoids; as an interface with high frequency sensors or switches; and amplifying highly inductive 2-wire loads such as motor brakes or contactors.
The Microopto Actor solid state relay is a switching amplifier for actuators up to 24VDC and 2A, with inductive loads such as solenoid valves and contactors. It supports 3-wire actuators, enabling the operation of solenoids and other motors in automation applications. This relay features suppression diodes and varistors for short-circuit protection and security against application-related transients and spikes.
Functioning as an intelligent MOSFET (DC), the Microopto Actor provides low contact resistance and very small leakage currents. This ensures minimal power loss and heat development, making the Microopto an efficient and reliable solution for switching higher load currents.
The Microopto 300VDC solid state relay is a switching amplifier for high inductive loads up to 300VDC and 1A. It is ideal for switching motor brakes and contactors. It features a power boost in the load circuit that compensates for transient feedback (20A for 20ms/5A for 1s) to protect from electrical spikes. The Microopto 300VDC also has suppression diodes and varistors for additional circuit and overvoltage protection.
The Microopto 100kHz solid state relay is a switching amplifier for high frequencies up to 100kHz. It is designed to ensure rapid signal transition while providing isolation without a delay. Typical uses include high frequency pulses such as speed monitors or count-data passing between sensors.
