Product Details

The AB 1771-OW16 module is an electromechanical relay contact output module that features a total of 16 grouped outputs. This module also features an economical design for power applications, with each of its output independently isolated from the logic circuitry. The use of a resistor-capacitor (RC) network filter across the 1771-OW16 module’s contacts is required to suppress arcing on it. The RC network filter also minimizes the effects of electromagnetic noise (EMI) that can disrupt the operation of the neighboring electrical equipment, including the AB 1771 I/O chassis.

The 1771-OW16 AC/DC relay contact output module is part of the AB 1771 series. It is a module in the AB 1771 I/O system that requires a properly-installed system chassis for proper operation. The wiring connections are made with the field wiring arm known as the AB 1771-WN wiring arm. The wiring arm acts as a terminal strip for connecting the module terminals to the chassis. This part also allows for the removal and insertion of the relay contact output without disconnecting the wiring. The 1771-OW16 module is powered via the 1771 I/O chassis backplane and it requires a current load of 1300 mA. The maximum continuous current per module is rated at 1280 W for DC voltage and 1440 VA for AC voltage. The 1771-OW16 module has a switching frequency of 1/3 Hertz at the maximum load, and an operate/release time of 10 milliseconds maximum. The 16 LED status indicators of the module light up whenever the corresponding relays are energized
