The 1734-OE4C is an Allen-Bradley POINT IO module that features Four (4) single-ended, analog output modules which provide 0 to 20 mA or 4-20 mA analog electrical signals. This analog output is used for controlling processes that requires modulating control for increased accuracy, efficiency and flexible control techniques.

The module has a compact form and designed for DIN rail mounting. This module may be used with POINT IO communication adapter such as ProfiBus, ControlNet and Ethernet adapters. The 1734-OE4C memory register is accessible by connecting online to the Programmable Logic Controller’s (PLC) processor. The module’s register is composed of Channel Data and Channel Status. The module’s register size is 4 Bytes.

The 1734-OE4C has Module Status and Network Status indicator light as well as Status indicators for every channel. These indicators are installed on the module’s front panel to indicate the module status, network and channel activity.

Compatible wiring assembly for this analog output module are 1734-TB or 1734-TBS. The 1734-OE8C has a dimension of 56.0 x 12.0 x 75.5 mm (2.21 x 0.47 x 2.97 in.) and weighs 36 g (1.235 oz). Recommended signal wire sizes for this module measures 0.25 to 2.5 mm. sq. or 22 to 14 AWG solid or stranded copper wire rated at 100 ° C (212 ° F), or greater. Recommended maximum insulation size is 1.2 mm (3/64 in.).
