Product Description
The Allen-Bradley 1734-OX2 Point I/O module is a 2-channel Form C relay output module. It handles 5-28.8V DC or up to 240V AC loads at 2A, with a 2mA leakage current. Power ratings reach 250W at 125V AC (resistive) or 31VA at 125V DC (inductive). Key specs include 30 milliohms contact resistance, a 0.3Hz switching frequency, 10ms operate/release time, and 1.2ms bounce time. Minimum load is 5mA per point, with a contact life of 1 million cycles (resistive) or 100,000 cycles (inductive). It features LED indicators for status and output, a 7-position keyswitch, and mounts on a 1734-TB or -TBS base. It draws 100mA at 5V DC, dissipates 0.5W (1.7 BTU/hr max), and offers 250V isolation. Dimensions are 2.21x0.47x2.97 inches, weighing 1.15oz. It operates from -4 to 131F with 5-95% non-condensing humidity. Ideal for diverse voltage applications, it's a cost-effective, rugged distributed I/O solution for CompactLogix and ControlLogix. Each channel has a common terminal, with N.O. and N.C. connections. Power is supplied via the internal bus. External fusing is recommended.
Is Your Device Showing These Signs?
The Allen Bradley 1734-OX2 POINT I/O module commonly experiences field wiring termination failures, requiring inspection and proper torque of terminal blocks. Corrosion on the module's pins and backplane connector causes communication errors; cleaning with appropriate solvents and reseating resolves this. Output failures stem from shorted field devices or exceeding the module's current rating; verify field wiring and load requirements. Firmware corruption leads to erratic behavior; a firmware upgrade through Rockwell Automation's software resolves this. Power supply fluctuations induce intermittent faults; ensure a stable 24V DC power source.
Technical specifications
The Allen-Bradley 1734-OX2 Point I/O module is a 2-channel relay output module capable of handling both DC and AC loads. It features key specifications like low contact resistance, fast switching times, and long contact life. It's designed for distributed I/O systems, offering LED indicators, a keyswitch, and easy mounting. It's compact, rugged, and suitable for a wide range of voltage applications, making it a cost-effective solution for CompactLogix and ControlLogix systems. It requires external fusing and uses the internal bus for power.
Our Repair Process for the
1734-OX2
Our repair process for the Allen Bradley 1734-OX2 POINT I/O module begins with a thorough inspection of field wiring terminations, ensuring proper torque of terminal blocks. Technicians then meticulously clean module pins and the backplane connector with specialized solvents, reseating the module to eliminate corrosion-induced communication errors. Output failures necessitate verification of field wiring and load requirements, confirming they align with the module's current rating. Suspected firmware corruption is addressed through a mandatory firmware upgrade using Rockwell Automation's software. Finally, the 24V DC power source is assessed to guarantee stable voltage, mitigating intermittent faults caused by power supply fluctuations.
