Product Review

The OAC5 output module is used for controlling or switching AC loads of 12-140 VAC. Each module provides up to 4000 volts (transient) of optical isolation between the field devices and the control logic. This module is equivalent to a single pole, single throw, normally open contact (FORM A, SPST-NO, Make). All AC output modules feature zero voltage turn-on and zero current turn-off. Typical uses and applications for AC output modules include switching the following loads: relays, solenoids, motor starters, heaters, lamps or indicators. Operating ambient temperature: -30 to 70 degree C. Isolation, input-to-output (Transient): 4,000 Vrms. Minimum load current: 20 milliamps. Operating frequency: 25-65 Hz. Turn-on time: 1/2 cycle maximum-zero voltage. Turn-off time: 1/2 cycle maximum-zero current. DV/DT - off-State: 200 volts/microseconds. DV/DT - Commutating: snubbed for rated 0.5 power factor load. Output voltage drop maximum peak: 1.6 volts. Off-state leakage at nominal voltage - 60 Hz: 5 milliamps rms 2.5 milliamps rms for OAC5A OAC15A, and OAC24A at 120 VAC.
