About 1734-OW4
The Allen-Bradley 1734-OW4 is a POINT O/I module. This module is a discrete output module with Four (4) Single Pole, Single Throw (SPST) Normally Open (N.O.) contacts. These contact outputs are voltage-free contacts and supports operating with 5-30 VDC; 120 VAC and 250 VAC voltages. It has a compact and small design, ideally used for implementing distributed I/O architecture and supports installation to a DIN rail and couples with an appropriate terminal base for wiring of signal an input power with applicable bases such as 1734-TB, 1734-TBS, 1734-TOP, or 1734-TOPS. When mounting
