GE 8164-4002 Digital I/O Cards

The GE 8164-4002, also cataloged as the 8164-4002 Digital Output Module, operates as a dedicated hardware component for 24 VDC discrete signal switching and actuator execution within GE GEM 80 PLC platforms.

Hardware Specifications

Backplane Bus Communication Velocity and I/O Density Scaling

Engineered for high-density field actuation, the 8164-4002 controls up to 32 discrete 24 VDC loads rated at 0.5 A per channel. The module manages high I/O density scaling while isolating backplane control logic from field-side inductive transients, preventing electrical noise from slowing backplane bus communication velocity or disturbing execution cycles on adjacent processor cards.

Frequently Asked Questions

Q: Can channels on this 32-way digital output module be hot-swapped during PLC rack operation?

A: No. Primary backplane power and external 24 VDC field load supplies must be de-energized and locked out prior to removing or inserting the module to prevent electrical arcing or backplane logic corruption.

Q: What is the maximum load current capacity per channel for the 8164-4002 module?

A: Each individual output channel is rated for a maximum switching capacity of 0.5 A continuous at 24 VDC.

Field Installation Guidelines

1. Power down the GEM 80 rack and isolate all external 24 VDC field power sources prior to installation.
2. Align the module chassis guides with the target slot on the GEM 80 backplane and insert until the connectors fully mate.
3. Fasten top and bottom retaining screws securely to guarantee mechanical retention and solid frame grounding.
4. Wire field outputs ensuring proper fuse protection per group and solid earth ground bonding for field cable shields.
