Relay Driver Type W061

Summary The W061 is a W-series module containing four all-silicon drivers designed to control relays and solenoids. Key features include:

• Capabilities: It can handle up to 250 mA per output and supports positive supply voltages between 2V and 55V.
• Inputs: Features gateable inputs that require 2 mA at ground. Multiple-input AND gate functionality can be achieved using external diodes (such as R001 or R002).
• Outputs: Loads are connected between the outputs and an external positive supply. Pin V must be connected to the positive supply to protect output transistors from inductive load back-EMF.
• Performance: The circuit has a typical switching delay of 1 µs, though inductive loads may result in significantly longer current decay times.
• Power Requirements: The module requires +10V (at 70 mA) and -15V (at 8 mA).
