100 mA Indicator and Relay Driver Type W051

Summary: The W051 is a W-series electronic module containing seven inverter amplifiers designed to drive medium-power devices such as relays and indicators. Each of the seven channels can supply up to 100 mA at ground. The outputs are diode-clamped to -15V to protect the circuitry from overvoltage when driving inductive loads. The module operates with standard input levels of ground and -3V, and requires power supplies of +10V and -15V.
