About the IS220PDOAH1A
Characterized as a Discrete Output Pack the IS220PDOAH1A model was designed with interfacing up to two I/O Ethernet networks and other discrete output terminal boards in mind. One special function of this model is that it can control up to twelve relays as well as accept feedback signals from other terminal boards. The typical relays that can be used with this model are solid-state relays and electromagnetic relays. The solid-state relays are used with the TRLYH1B, C, D, and F terminals whereas the electromagnetic relays are used with the TRLYH1E boards. There are also:
- multiple processors
- status-indicating LEDs
- local power supplies for monitoring and sequencing
- a high-speed processor with flash and RAM memory
- double RJ45 Ethernet connectors
- a three-pin power input
- a processor board embedded in the IS220PDOAH1A pack
- an output enable feature that is used with the IS220PDOAH1A pack
During the application in which power is given to the pack, all of the outputs will be disabled until a number of internal self-tests have been fulfilled. The enable function can provide paths that are independent of the command which will ensure that the relays are staying dropped out during the initialization and power-up of the pack.
IS220PDOAH1A Discrete Output Pack Standard Hardware
This IS220PDOAH1A Discrete Output Pack device's special modular I/O Mark VI Series assembly version and domestic original GE manufacture were determined upon analysis of its initial dual-functional IS220 series tag. Some of the other relevant information dictated through this medium include the IS220PDOAH1A Discrete Output Pack's:
- PDOA functional product acronym
- Group one Mark VI Series grouping
- Conformal PCB coating style
- A-rated revision
