The Spectrum Controls 1769sc-IF8U module is a CompactLogix compatible module. This module is a universal analog input module that has Eight (8) channels individually configurable for voltage, current, thermocouple inputs or Four (4) channels when configured for RTD input.

The 1769sc-IF8U is manufactured by an encompass partner company of Allen-Bradley for use with MicroLogix 1500 and CompactLogix controllers.
This module supports a wide variety of Thermocouple sensors such as J, K, T, B, E, R, S, N, C. Compatible Resistance Temperature Detector (RTD) are 3 or 4-wire RTD with specific RTD types of PT385/3916, Ni618/672, NiFe518, Cu426. It may also be configured for standard current signals such as 0-20 mA and 4-20 mA while configurable voltage signals are ±50 mV, ±100 mV, 0-5 V, 1-5 V, 0-10 V, ±10 V.

Available channel configuration choices for this module are Eight (8) channels following Voltage/Current/Thermocouple configuration, Six (6) channels configured as Voltage/Current/Thermocouple and One (1) channel configured for RTD/Resistance, Four (4) channels configured as Voltage/Current/Thermocouple and Two (2) channels RTD/Resistance, Two (2) channels Voltage/Current/Thermocouple and Three (3) channels RTD/Resistance and Four (4) channels RTD/Resistance.
This module has a high resolution of 16-Bit with adjustable filter frequencies of 10 Hz, 50 Hz, 60 Hz, 250 Hz, and 1000 Hz and selectable update times of 2.44, 0.53, 0.45, 0.15, and 0.07 ms.

Recommended signal cables for this module are shielded, twisted-pair TC extension wire for Thermocouple inputs while Belden 8761 or equivalent for RTD, mV, V or mA input signals.

This module is provided with a set of status indicators that helps identify the user the operational status of the module and the possible problem source.

The Allen-Bradley 1769-SCIF8U is a Spectrum Control universal analog input module. This module is configurable for Thermocouple, Voltage, or Current inputs or Four (4) RTD or resistance inputs. This module is compatible for use with CompactLogix controller and MicroLogix 1500 controllers. It has Eight (8) onboard jumpers are present to configure the current and voltage modes.
Thirty-two input types are available with this module and each channel can be programmed individually. The input ranges for the 1769-SCIF8U are 0-20 mA and 4-20 mA for current, 0-150, 0-1000, and 0-3000 Ω for resistance, +/-50 mV, +/-100 mV, 0-5 V, 1-5 V, 0-10V, and +/-10V for voltage, J, K, T, B, E, R, S, N, and C for thermocouple, and PT385/3916, Ni618/672, NiFE518, and Cu426 for RTD. You can use any combination of inputs to this module and when using thermocouples and note that cold junction compensation is present.
The 1769-SCIF8U module has 6 filter frequencies available, 10 Hz, 50 Hz, 60 Hz, 250 Hz, 500 Hz, and 1000 Hz, and these are individually selectable per channel. There is onboard error checking and open circuit detection for most input types. This module also has auto-calibration and comes with 16-bit resolution.
The backplane current rating of this module is 45 mA at 24V and 150 mA at 5V. It also has a thermal dissipation of 3 W maximum and rejection ratio of 115 dB at 50-60 Hz for common mode and 85 dB at 50-60 Hz for normal mode. The input impedance of this module is greater than 10 MOhms for thermocouple, RTD, and voltage and less than 250 Ohms for current. Its continuous electrical isolation is 10V DC for channel-to-channel isolation and 125V AC for both field-wiring-to-backplane and for field-wiring-to-chassis-ground. The module also comes with a +/-30V DC continuous input overvoltage protection and 28 mA continuous input overcurrent protection.
