Analog Output Hardware & Reliability

• Each channel operates with a 16-bit DAC controlling a high-compliance transistor amplifier.
• Includes internal temperature monitoring for overheat protection.
• Mechanical normally-open relays control output enable or disable state.
• LED indicators show relay and output status in real-time.
• Feedback monitoring uses a 50Ω resistor on the terminal board to ensure accuracy.

Installation Guide

• Firmly mount the terminal board and align the DC-37 connector before fastening.
• Ensure bracket alignment prevents stress on connectors.
• Connect one or two Ethernet cables; ENET1 is typically used for R controller connection.
• Attach the 3-pin power connector; hot-plugging is safe due to the soft-start circuit.
• Configure using ToolboxST* software; access help with the F1 key.

Self-Diagnostics & Function Tests

• Power-up tests verify RAM, flash memory, Ethernet ports, and processor health.
• Constant power supply validation ensures uninterrupted operation.
• Hardware set matching verifies CPU, acquisition, and terminal board IDs.
• Analog current feedback checks confirm DAC performance accuracy.
• Relay compliance is constantly monitored against feedback indicators.

Package Contents

• 1 × IS220PAOCH1A Analog Output Module (PAOC I/O pack)
• 1 × DC-37 Connector
• 1 × Mounting Bracket
• Terminal boards (TBAOH1C or STAOH1A/H2A) sold separately
• Shipping available via FedEx, UPS, or DHL with tracking support

Alarms & Troubleshooting

• Out-of-range feedback indicates mismatched command and output currents.
• Verify commands remain within the 0–20 mA range.
• Inspect all field wiring and connectors for continuity or damage.
• If multiple channels fail simultaneously, replace both the terminal board and I/O pack.

FAQ

• Q: What resistance load is required for reliable 0–20 mA output?
  A: Maintain the minimum series resistance defined on the terminal board screws across the 0–20 mA range.
• Q: How should I handle repeated out-of-range alarms?
  A: Verify command values, check wiring, and ensure feedback alignment. Replace hardware if the issue persists.
