Description

GE IS220PSVOH1B Servo Control I/O Pack
Description:

IS220PSVOH1B， the Servo Control (PSVO) I/O pack provides the electrical interface between one or two I/O Ethernet networks and a TSVC servo terminal board. The I/O pack containscommon processor board and an application board specific to the servo function. ThePSVO uses the adjacent WSVO servo driver module to handle two servo valve positionloops, with a selection of five servo valve output currents from 10-120 mA dc. The I/O pack supplies LVDT excitation, and accepts eight LVDT feedbacks and two pulse rateinputs from fuel flow meters. Input to the I/O pack is through dual RJ-45 Ethernet connectors, and 28 V dc power issupplied from the terminal board. Output is through a DC-62 pin connector thatconnects directly with the associated terminal board connector. Visual diagnostics are provided through indicator LEDs.

Compared with IS220PSVOH1A, IS220PSVOH1B not only contains a BPPC processor, but also requires firmware V04.09 or later.
