GE IC693UDR002NP1 Programmable Controller

The GE IC693UDR002NP1, also cataloged as the IC693UDR002 Programmable Controller (PLC), operates as a dedicated hardware component for discrete logic and analog processing tasks within GE Series 90-30 platforms. Combining a CPU, internal power supply, 16 isolated AC input points, and 12 relay output points in a single compact housing, the unit executes Relay Ladder Logic or C programs without requiring external backplane racks.

Hardware Specifications

Deterministic Network and High-Density Control Features

The IC693UDR002NP1 delivers dynamic backplane bus communication velocity across its integrated RS-232 and RS-485 interfaces, executing logic cycles at a rate of 1.2 ms per 1000 words. Dual serial ports facilitate simultaneous HMI panel interaction and RS-485 multi-drop networking across Series 90-30 platforms. Supporting system expansion up to 8 additional modules (scaling to 128 discrete points and 64 analog channels), the unit ensures full firmware flash compatibility while executing real-time I/O density scaling.

Frequently Asked Questions

Q: How does the IC693UDR002NP1 retain program logic during a main power failure?

A: The module utilizes dual energy storage: a 1000 uF capacitor filters brief power interruptions, while an internal BR-2/3A lithium battery maintains memory contents for up to 5 years.

Q: What programming environments support the IC693UDR002NP1 controller?

A: The module can be programmed in Relay Ladder Logic or C language using standard GE Logicmaster or VersaPro software tools connected via the 15-pin RS-232 port.

Q: What electrical isolation and switching limits apply to the onboard I/O channels?

A: The 16 discrete 120 VAC inputs feature optical isolation for noise rejection, and the 12 electromechanical relay outputs switch up to 2 A per channel at 120 VAC or 24 VDC.

Field Installation Guidelines

1. Mount the controller directly inside a control cabinet on standard DIN-rail or panel surfaces, maintaining vertical orientation for passive heat dissipation.
2. Verify system power is isolated before attaching field wiring to the top and front removable terminal block connectors.
3. Wire the 16 AC inputs (120 VAC) and 12 relay output circuits using recommended gauge conductors, keeping high-voltage wiring physically separated from RS-232 and RS-485 serial cables.
4. Ensure functional ground wiring is securely bonded to the main protective earth terminal to guarantee optical isolation integrity.
5. Check battery voltage and insertion polarity for the BR-2/3A lithium cell prior to commissioning to ensure non-volatile RAM retention.
