Board Composition

• Four circuit boards in one assembly
• One shared processor board
• Two application I/O boards
• One terminal board (TCAT or TCAS)
• Whole module is least replaceable unit
• No individual board replacement

Connectors & Ports

• Dual RJ45 Ethernet connectors
• P5: 28 Vdc power input
• P4: Power to JGPA board
• P1 and P2: Two 68-pin cables to TCAT
• 120 Euro-style box terminals on module edge

Signal Split Method

• TCAT terminal board fans inputs to PCAA modules
• One TCAT can feed 1, 2, or 3 PCAA modules
• Some signals wire directly to PCAA terminals
• Signals exclusive to one PCAA module
• PCAA can replace TCAT if fanning not needed

Installation Steps

• Mount PCAA module firmly in rack
• Connect P4 on PCAA to JGPA power connector
• Attach two 68-pin cables from P1/P2 to TCAT
• Finger tighten mounting screws only (critical for grounding)
• Connect one or two Ethernet cables as needed
• Single IONet connection works on either port
• For dual connections, match ENET1 to proper controller
• Verify JGPA shield wires are grounded
• Power on via P5 connector
• Check power and Ethernet status LEDs

Grounding Notes

• Finger tighten screws into PCAA and TCAT
• Overtightening may cause communication issues
• Module may not read TCAT electronic ID if loose
• JGPA shield terminals normally ground to sheet metal
• Some cases need separate shield ground wire
• Use insulated mounting hardware if separate ground needed

Frame Rates & Redundancy

• Runs at 10 ms or 40 ms frame rates
• Supports simplex, dual, and TMR systems
• Compatible with all Mark VIe I/O packs
• Compatible with all Mark VIe controllers

Processor Board Features

• Fast processor with RAM and flash
• Two independent 10/100 Ethernet ports
• Watchdog timer and hardware reset
• Internal temperature sensor
• Status LEDs
• Reads electronic IDs on other boards
• Soft start and current limiter on power input
• Local power supplies with sequencing and monitoring

Accuracy Specifications

• Includes aging, temperature, and power variance
• Includes product variance effects
• Typical accuracy listed at 25°C
• Specified accuracy is worst-case limit

• Warranty: 12 months from delivery
• Shipping: FedEx, UPS, DHL
• Fast worldwide delivery

Typical Applications

• Gas turbine control systems
• Distributed control systems (DCS)
• Power generation plants
• Industrial automation with Mark VIe

Professional FAQ

• Can I replace just one board inside this module? No. The whole module is the least replaceable unit. No board-level repair.
• What happens if I overtighten the mounting screws? Module may not read TCAT electronic ID. Communication can degrade.
• Do I need a TCAT terminal board for this module? Not always. PCAA can work alone if you don’t need fanned inputs.
• What power supply do I need? 28 Vdc ±5% through P5 connector. Current limiter built in.
• Is this module hot-swappable? Refer to GE Mark VIe manual. Most Mark VIe modules support hot swap.

Experience-Based FAQ

• My module won’t see the TCAT board. What’s wrong? Check mounting screws. They must be finger tight only. Not loose, not tight.
• Can I use a longer cable than standard? Use only GE-specified 68-pin cables. Longer cables may cause signal loss.
• The accuracy seems off. What to check? Verify temperature is within -30 to 65°C. Check power supply stability.
• Do I need both Ethernet ports connected? No. One port works fine. Dual ports are for redundant networks only.
• How do I know if my JGPA is grounded correctly? Measure continuity between shield terminal and ground. Use a multimeter.

Selection Guide

• Step 1 – Count your analog inputs. Need up to 25? This fits.
• Step 2 – Check output type. This provides 4-20 mA and servo outputs.
• Step 3 – Confirm system type. Works with simplex, dual, or TMR.
• Step 4 – Verify temperature range. Must be -30 to 65°C.
• Step 5 – Decide if you need TCAT for fanned inputs.
• Step 6 – Order JGPA board separately if needed for shield grounds.
