Summary of NEW PHOTORELAYS WITH LOW LED TRIGGER CURRENT FOR BATTERY POWERED SECURITY AND AUTOMATION DEVICES
Toshiba introduced the TLP170AM and TLP170GM photorelays for security, building automation, and industrial equipment. TLP170AM supports 60V OFF-state, 0.7A ON-state (2.1A pulse); TLP170GM supports 350V OFF-state, 0.11A ON-state (0.33A pulse). Both use a sensitive photodiode array with a 1mA max trigger LED current to reduce input power, low ON-resistance, and high isolation (3750Vrms). Packaged in 4-pin SO6, they meet UL, cUL, and VDE safety standards and target battery-powered sensors, PLCs, I/O interfaces, and replacement of mechanical relays.
Parts used in the Photorelays TLP170AM and TLP170GM Project:
- TLP170AM photorelay
- TLP170GM photorelay
- 4-pin SO6 package (packaging for the photorelays)
- Photodiode array (internal sensitivity element)
- Trigger LED (input LED for activation)
Toshiba Electronic Devices & Storage Corporation has introduced the TLP170AM and TLP170GM two new photorelays that can be used in security systems, which are used in building automation and other industrial equipment.
The TLP170AM has a rated OFF-state output terminal voltage of 60V and constant ON-state current (ION) of 0.7A with the pulse operation of up to 2.1A. The TLP170GM is a 350V version with an ION of 110mA constant current and 330mA pulse operation.
The new photo relays are designed with a maximum trigger LED current of 1mA for reducing the input-side power loss by increasing the sensitivity of the photodiode array. The devices provide lower power consumption and longer operation of devices when they are used in ON/OFF control in battery-powered security devices and various sensors.
