Functional Overview of the IS220PAOCH1A Pack

• The IS220PAOCH1A acts as the electrical interface between the I/O network and analog terminal board.
• It uses a BPPB processor board and a dedicated analog output acquisition board pair.
• Each output uses a 16-bit DAC to drive an external transistor amplifier for precise regulation.
• An internal temperature sensor monitors board temperature and alerts the control system.
• Mechanical normally-open relays enable or disable each output for added safety.
• Current feedback comes from a 16-bit ADC measuring across a 50-ohm resistor on the terminal board.

Compatibility and Control Modes for GE IS220PAOCH1A

• Simplex: Uses one I/O pack with one or two Ethernet ports – cost-effective for non-critical tasks.
• Dual: Two parallel packs with up to two Ethernet connections each – provides automatic failover.
• TMR (Triple Modular Redundant): Three packs with dedicated networks – 2-out-of-3 voting for highest integrity.
• The PAOCH1A is compatible with terminal boards TBAOH1C and STAOH1A/H2A (not DTAO DIN-rail).
• Supports BPPB processor board; functionally compatible with BPPC (controlST V04.06 and later).

Technical Specifications – IS220PAOCH1A

• Manufacturer: General Electric (GE) – Mark VIe series.
• Analog Outputs: 8 channels, 0–20 mA, 18V compliance, 900 Ohm max load.
• Resolution: 16-bit DAC per channel with 16-bit ADC for feedback.
• Accuracy: ±0.5% over full temperature range (-30°C to 65°C).
• Operating Temp (external): -40°C to 70°C (derating applies for dense layout).
• Minimum Load Impedance: Defined by series equivalent resistance on terminal board.
• Diagnostic LEDs: Visual status for each relay and communication health.

Installation Guide for IS220PAOCH1A

• Mount the terminal board firmly before connecting the I/O pack.
• Directly connect the PAOC I/O pack(s) to the connector on the terminal board.
• Fasten mechanically using threaded studs next to Ethernet ports into the mounting bracket.
• Position the bracket to avoid right-angle forces on the DC-37 connector.
• Connect Ethernet cables – one or two ports; ENET1 to R controller for dual connections.
• Apply power via the side connector – soft-start feature regulates inrush current.
• Configure using ToolboxST software; press F1 for Component Editor help.

Self-Diagnostic Features

• Power-up self-test – checks processor, Ethernet ports, RAM, and flash memory.
• Continuous monitoring of internal power supply operation.
• Hardware verification – compares electronic ID data from CPU, acquisition, and terminal boards.
• Current feedback check – compares commanded current with sensed output.
• Relay status check – continuously verifies output suicide relay condition.

Troubleshooting – Alarms and Solutions

• Alarm: Output exceeds valid range (0–20 mA) – check command value.
• Alarm: Out-of-range feedback – verify feedback matches expected command.
• Alarm: Hardware fault – inspect field wiring and connectors.
• Solution: Replace terminal board and I/O pack if all active feedbacks are unhealthy with valid command.
