01 - CONTROL ROLE
From Network Command to Field ContactThe IS220PDOAH1B provides the discrete-output interface in a Mark VIe control arrangement. It works with specified TRLY or SRLY terminal relay boards, where the selected board determines the applicable contact voltage and current capability.This means the pack and relay board must be treated as one output assembly during replacement selection. |
| Pack supply 24-28 VDC |
Input current 0.71 A maximum |
Ambient -30°C to +65°C |
| TRLYH1F / TRLYH2F / SRLY | 30 VDC, 5 A DC contact output |
| TRLYH2E | 28 VDC, 7 A DC contact output |
| TRLYH3E | 140 VDC, 2 A DC contact output |
| Compatible families | TRLYH2E, TRLYH3E, TRLYH1F, TRLYH2F, SRLYH1A, SRLYH2A variants |

Confirm packIS220PDOAH1B revision |
| 01 - Does IS220PDOAH1B have one universal output rating? No. The field-contact rating is established by the connected relay board: TRLYH1F or TRLYH2F arrangements are rated 30 VDC at 5 A, TRLYH2E is rated 28 VDC at 7 A, and TRLYH3E is rated 140 VDC at 2 A. |
02 - Can IS220PDOAH1B move from TRLYH2E to TRLYH3E without an engineering change? Not as a direct like-for-like change. The two boards serve different contact-voltage and current envelopes, so field voltage, protection, wiring and the configured output arrangement must remain consistent with the selected board. |
| 03 - Which IS220PDOAH1B arrangements support relay-status monitoring? SRLYH1A and SRLYH2A arrangements can be used with optional WROB, WROG, WROF or WROH monitoring boards. The monitoring-board suffix and wetting-power arrangement should be matched to the installed assembly. |
04 - How should an inductive load be treated with IS220PDOAH1B? The relay contact rating alone does not account for coil release energy. Contactors, solenoids and interposing relays should retain the suppression method used by the approved field circuit so that opening transients do not shorten contact life or disturb adjacent channels. |
| 05 - Is IS220PDOAH1B automatically interchangeable with IS221PDOAH1B or an H1A pack? No automatic interchangeability should be assumed. IS220 and IS221 versions have different supported terminal-board groupings, while earlier H1A assemblies were qualified with a narrower relay-board arrangement. The installed pack revision and terminal-board combination define the valid replacement path. |
