The OAC15 is an AC output module used for controlling or switching AC loads. It operates with a nominal line voltage of 120 VAC (12–140 VAC range) and is controlled by a nominal 15 VDC logic voltage (9-16 VDC range). This module features a current rating of 3 amps at 45 °C, zero voltage turn-on, zero current turn-off, and provides 4000 Vrms of transient optical isolation between the control logic and the field device. Its rugged construction makes it suitable for industrial applications such as switching relays, solenoids, motor starters, and heaters.
