English | OAC24A AC Output, 24-280 VAC, 24 VDC Logic |
  |
The OAC24A 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
