The Allen-Bradley 1771-OZL is a PLC-5 series output module featuring dry-reed relays, known for their hermetically sealed design that makes them ideal for harsh or noxious environments. This module is designed for low-power, low-voltage applications and contains 8 outputs organized into 4 pairs. It supports voltage ratings ranging from 0 to 24 Volts AC RMS and 0 to 24 Volts DC. Caution is advised to avoid surge currents, which may harm the sensitive relay components.
