More Information

Overview Manuals Relay Paths Feedback Board Pairing Output Limits

Features:

  • Controls 12 terminal-board relay channels.
  • Returns relay condition data independently of field commands.
  • Works with defined TRLY and SRLY output-board combinations.
IS220PDOAH1B converts controller network commands into relay-control signals for the connected output board.

Feedback monitoring gives the control system a separate view of relay condition rather than relying only on the command bit.

The pack and terminal-board identity data must agree before the configured output arrangement is accepted.

The General Electric IS220PDOAH1B Mark VIe Discrete Output Pack is listed as Active / Available from OEM. Apter Power provides IS220PDOAH1B quotations, product documentation and system-matching support.

Command Channel Structure

  • Channel Count: IS220PDOAH1B controls 12 relay outputs
  • Network Input: Commands arrive through the I/O Ethernet interface
  • Drive Stage: Pack logic operates the terminal-board relay circuits
  • Enable Path: Output operation waits for successful initialization

Output Condition Monitoring

  • Relay State: Terminal-board feedback returns detected status
  • Comparison: Commanded and monitored conditions can be evaluated
  • Identity: Electronic IDs establish the installed board pairing
  • Attention: Pack status reports detected hardware or configuration faults

Supported Output Hardware

  • TRLYH2E: Supports the defined 28 VDC contact arrangement
  • TRLYH3E: Provides the certified 140 VDC output option
  • TRLYH1F/H2F: Provide rated voted relay-contact configurations
  • SRLYH1A/H2A: Provide supported simplex relay-output connections

Certified Electrical Boundaries

  • Input Supply: Operate IS220PDOAH1B from 24–28 VDC
  • Supply Current: Maximum pack input is 0.71 A
  • Ambient: Certified range is -30 to +65 °C
  • Field Rating: Apply the rating assigned to the connected terminal board
Description
For the Mark VIe distributed I/O platform, General Electric IS220PDOAH1B is a discrete output pack that controls 12 relay channels and receives status feedback from the attached output terminal board. It places the processor and output acquisition functions in one field-mounted assembly.

Controller commands arrive at IS220PDOAH1B over its Ethernet interfaces, and pack logic drives the terminal-board relay circuits. Separate feedback paths compare commanded and detected conditions, while the selected TRLY or SRLY board establishes the field-contact arrangement, output rating and redundancy form.

A 24–28 VDC supply powers IS220PDOAH1B, and the certified pack operates over an ambient range of -30 to +65 °C. Power-up checks, electronic board identification and continuous supply monitoring establish the required conditions before relay commands are enabled.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
IS220PDOAH1B receives a command but the returned status disagrees. How should the path be divided for testing?
Compare the IS220PDOAH1B command with terminal-board relay feedback, then trace the relay coil and feedback circuit separately from the field load.
A cabinet uses a different TRLY or SRLY board than expected. Why does that change the IS220PDOAH1B check?
IS220PDOAH1B supplies command and monitoring functions, but the attached terminal board establishes the contact arrangement, redundancy form and allowable field rating.
Every IS220PDOAH1B channel remains inactive after startup; what common conditions should be cleared first?
Verify IS220PDOAH1B pack power, Ethernet status, board identification and the output-enable condition before testing individual relay circuits.
Can a command bit alone prove that an IS220PDOAH1B relay has reached its requested state?
No. IS220PDOAH1B returns relay-condition feedback on a path separate from the command, so the detected status must also be reviewed.
Link LEDs are active but IS220PDOAH1B still reports attention. Where does that point the investigation?
Active link and traffic indications confirm the Ethernet path; then use the IS220PDOAH1B power, attention and board-identification status to investigate pack or hardware-pairing conditions.
To match IS220PDOAH1B with an existing cabinet, which installed details must be recorded?
Record the complete IS220PDOAH1B number, terminal-board number, redundancy arrangement and field-contact rating before confirming the combination.
