OPERATING INSTRUCTIONS

FP-QUAD-510

4-Axis, Quadrature Input Module

These operating instructions describe the installation, features, and 
characteristics of the FP-QUAD-510. For details on configuring 
and accessing the FP-QUAD-510 over a network, refer to the user 
manual for the particular FieldPoint network module you are using 
with the FP-QUAD-510.

Features

The FP-QUAD-510 is a FieldPoint quadrature input module with 
the following features:

Four independent 32-bit position counters with individual 
Phase A, Phase B, and Index input terminals

Velocity measurement capabilities

Programmable reset on index mode

Sinking inputs, compatible with TTL or differential devices

Inputs protected to ±250 VDC

Hot plug and play operation

2,500 Vrms input-to-output isolation

Double insulated for 250 V safe working voltage

Power Requirement 

The FP-QUAD-510 is powered via the local backplane bus from 
the FieldPoint network module. The FP-QUAD-510 is a 
high-power consumption module and requires more than the 
nominal power allocated to an I/O module from the network 
module. In some applications, this could limit the number of I/O 
modules that you can connect to a single network module.
