Product Description
The Allen-Bradley 1734-OE2C is a 2-channel, unipolar analog output module with single-ended, non-isolated current outputs (0-21 mA, 13-bit resolution). It converts digital code to analog signals, consuming 4 bytes and producing 2 data bytes. Selectable output ranges are 0-20mA and 4-20mA (default), with default scaling points of 1638 (4 mA) and 8191 (20 mA). Open-wire detection triggers a general status bit and a blinking red channel indicator. Accuracy is 0.1% full-scale at 25C, with a temperature drift of 30 ppm/C. Step response (63% FS) is 24 s, and current conversion rate is 16s. It supports a 0-750 Ohm resistive load, draws 75 mA at 5V DC, and dissipates 1.23 Watts (4.19 BTU/Hr). Isolation voltage is 50V continuous (2200V DC withstand for 60s). It requires a 24V DC (10-28.8V DC range) external supply, drawing 70mA (including 20mA outputs). The module features a 4-position key switch, measures 56 x 12 x 75.5 mm, and weighs approximately 36g. It's commonly used to actuate modulating final control elements (FCEs) and re-transmit analog data. For optimal grounding and corrosion resistance, use a zinc-plated, yellow-chromated steel DIN rail for installation. The Series C module is compatible with DeviceNet and Profibus communication adapters.
Is Your Device Showing These Signs?
The Allen Bradley 1734-OE2C POINT I/O analog output module commonly experiences issues such as signal drift, output inaccuracy, and communication failures on the EtherNet/IP network. Technicians address these problems by recalibrating the module, replacing faulty digital-to-analog converters (DACs), and resolving network configuration errors, including IP address conflicts and incorrect subnet masks. Corrupted firmware necessitates reflashing, and damaged terminal blocks require replacement to ensure proper signal integrity and reliable operation within the industrial automation system. Power supply fluctuations and excessive environmental temperatures contribute to component degradation, demanding voltage regulation and adherence to specified operating conditions.
