12 MicroLogix™ 1762-IQ8 DC Input Module

1762-IN004A-US-P

Input Specifications

Specification 1762-IQ8

Voltage Category

24V dc (sink/source)

(1)

Sinking/Sourcing Inputs - Sourcing/sinking describes the current flow between the I/O module and the

field device. Sourcing I/O circuits supply (source) current to sinking field devices. Sinking I/O circuits are

driven by a current sourcing field device. Field devices connected to the negative side (DC Common) of

the field power supply are sinking field devices. Field devices connected to the positive side (+V) of the

field supply are sourcing field devices.
