Description
The 1756SC-IF8U input module provides general analog (current, voltage, thermocouple, or RTD) functions on a single module. By replacing dedicated analog inputs, thermocouples, and RTD modules with a general-purpose module, the rack space is maximized without compromising cost performance. The module provides eight voltage, current, and thermocouple inputs, or four-channel RTD/resistance inputs. 32 input types can be individually programmed for each channel. This module comes with Rockwell Automation’s TechConnect™ support, at no additional cost.
ControlLogix 1756SC-IF8U Features
1. Eight channels of voltage, current, resistance, RTD, or thermocouple inputs provide a flexible solution for analog monitoring applications.
2.With 1000 Vdc channel to backplane isolation; 1000 Vdc channel to chassis ground isolation; 12.5 Vdc channel isolation.
3. Provides several input noise filters, which can be selected channel by channel to minimize noise and customize installation at maximum speed.
4. Enhanced features include 16-21 bit resolution, digital filtering, user zoom, timestamp, and alarms.
5. Able to use any combination of input types at one time, and the accuracy is comparable to that of a dedicated analog module.
