GE IS230TNRLH1B LAY OUT DIN RAIL MODULE IS220PDOAH1B with IS200TRLYH1B
Description:
IS230TNRLH1B is GE MKVIe series LAY OUT DIN RAIL MODULE Assy. 
IS230TNRLH1B package including :
3 x IS220PDOAH1B Discrete Output Pack
1x IS200TRLYH1B discrete output terminal board with coil sensing

IS220PDOAH1B provides the electrical interface between one or two I/O Ethernet networks and a discrete output terminal board. The I/O pack contains a BPPx processor board and an acquisition board specific to the discrete output function. IS220PDOAH1B is capable of controlling up to 12 relays and accepts terminal board specific feedback. Electromagnetic relays (with types TRLYHIB, C, D, and F terminal boards) and solid-state relays (with type TRLYH#E boards) are available.

Dimensions of IS220PDOAH1B:
8.26 cm high x 4.19 cm wide x 12.1 cm deep

IS200TRLYH1B holds 12 plug-in magnetic relays. The first six relay circuits configured by jumpers for either dry, Form-C contact outputs, or to drive external solenoids. A standard 125 V dc or 115/230 V ac source, or an optional 24 V dc source with individual jumper selectable fuses and on-board suppression, can be provided for field solenoid power. The next five relays (7-11) are unpowered isolated Form-C contacts. Output 12 is an isolated Form-C contact, used for special applications such as ignition transformers.
