GE IC670MDL730 Digital Output Cards

The GE Fanuc IC670MDL730, also cataloged as the IC670 Discrete Output Module, operates as a dedicated hardware component for discrete signal actuation and load switching within Field Control I/O stations. The sub-assembly provides 8 positive logic sourcing outputs natively at the hardware tier to drive industrial field loads while enforcing localized electronic short circuit and overcurrent protection loops.

Hardware Specifications

Industrial Control & Drive Communications

• Backplane Bus Communication Velocity and Serial Loop Verification The internal logic processes digital output commands received from the local Bus Interface Unit (BIU) via a synchronous serial data link. To guarantee data verification prior to field execution, the module automatically echoes the raw serial stream back to the BIU in a loop layout; once verified, internal serial-to-parallel converters parse the commands into parallel registers to actuate the corresponding output channels.
• Profinet / EtherNet/IP Deterministic Network Telemetry The module shifts hardware fault flags directly into upper-tier process words via the network gateway. When an active channel encounters a short-circuit trip or an overcurrent anomaly, the module automatically generates a hardware fault report packet and routes it across the BIU backplane, passing real-time diagnostics up to the host controller over deterministic industrial networks.

Frequently Asked Questions

Q: How does the electronic short circuit protection function respond to field load failures?

A: The onboard monitoring hardware continually checks current flow. If a dead short manifests and the output current attempts to cross the 20 A threshold for a duration of 100 microseconds, the internal solid-state switch executes an electronic trip sequence, isolating the faulted channel and reporting a module fault code across the backplane.

Q: Can the IC670MDL730 operate safely on an unregulated DC power source?

A: The module accommodates a steady 18 to 30 VDC input range. To shield the electronic switches from line anomalies and switching spikes, the power terminals utilize an internal Metal Oxide Varistor (MOV) and decoupling capacitors, suppressing high-frequency noise and voltage surges before they propagate into the logic core.
