Hardware Specifications

Backplane Bus Architecture and Network Integration

The module relies on backplane bus communication velocity licenses to interface seamlessly with adapter nodes across distributed architectures. It maintains strict I/O density scaling profiles, enabling deterministic data updates while supporting firmware flash compatibility for seamless integration into standard EtherNet/IP control loops.

Ordering Information

• 1 1734-OE4C Analog Output Module
• 1 Removable terminal block base unit

Physical Mounting and Wiring Guidelines

• Rail Alignment: Secure the module onto a standard 35 mm DIN rail, ensuring the mechanical latch locks firmly against the profile.
• Cable Shielding: Terminate all analog signal cable shields to the designated functional earth ground to minimize high-frequency noise coupling.
• Conductor Strip Length: Strip field wiring insulation to expose 10 mm of bare copper for insertion into spring-clamp terminal points.

Frequently Asked Questions

• Q: Does the 1734-OE4C support hot-swapping during active operation?
• A: Yes, the module supports removal and insertion under power (RIUP) when installed on an approved terminal base within a grounded enclosure.
• Q: What conversion type and rate does the module utilize?
• A: The module performs digital-to-analog conversion at a conversion rate of 20 microseconds across its four single-ended output channels.
• Q: What is the output resolution specification?
• A: It provides 16 bits of resolution across 0 to 21 mA with an internal data conversion format of signed integer values.
• Q: How does the module receive external operating power?
• A: Operating power is supplied via an external DC supply providing up to 220 mA to drive the loop channels safely.
• Q: Can this module drive both 4 to 20 mA and 0 to 20 mA loops?
• A: Yes, the output signal range is software configurable to support either 4 to 20 mA or 0 to 20 mA field loops.
• Q: What backplane current is consumed for internal logic functions?
• A: Internal logic circuitry draws power directly from the POINT I/O adapter backplane bus interface.
• Q: Are the individual output channels galvanically isolated from each other?
• A: Outputs are single-ended and referenced to a common ground point within the module circuitry architecture.
• Q: How are operational faults indicated on the hardware?
• A: Diagnostic status is communicated via front-panel LED indicators displaying channel activity and communication health.
