The 1746sc-NI8U is an Eight (8) channel universal analog input module from Spectrum controls, an Allen-Bradley encompass partner company. This module is compatible for use with the Smart Logic Controllers (SLC) series of Allen-Bradley. It mainly features Eight (8) analog input channels that are compatible with a variety of inputs signals ad instruments. Specifically, this module supports Thermocouple sensors type J, K, T, B, E, R, S, N as well as PT385/3916, Ni618/672, Cu426. Compatibility with these sensing devices allows the module to be used in Temperature measurement and applications. Also, this module is also compatible with the direct input of 0 - 3000 Ohms of resistance signals for integration of transducers, typically motion and linear movement detection and measurement. This module is also compatible receiving standard 0-20 mA and 4-20 mA input signals for general purpose applications as well as a wide range of voltage signals including ±50 mV, ±100 mV, ±0.5 V ±2.0 V 0-5 V, 1-5 V, 0-10 V, and ±10 V. With the modules compatibility to a multitude of analog signals, the 1746sc-NI8U can be used in automation requirements of industrial machines and processes. The 1746sc-NI8U is a single slot width module that can be mounted directly to an SLC chassis. In addition, the module’s output table is directly compatible with SLC processors therefore, this module is simple to set up and operate.
The Spectrum Controls 1746sc-NI8U is an 8-channel universal analog input module for SLC 500 devices. The module is part of Allen-Bradley’s Small Logic Controller (SLC) systems. The 1746sc-NI8U is designed exclusively to be mounted into the 1746 input/output racks manufactured by Allen-Bradley. This module stores data from field devices like a thermocouple, RTD, millivolt signals, volt signals, milliamp signals, and CJC temperature analog data. The data is then available to Allen-Bradley SLC 500 processors which can take out information stored in the module’s image table. The Spectrum Controls 1746sc-NI8U has 8 channels, so users can connect up to 8 thermocouples or current or voltage inputs. Alternatively, users can use it for 4 RTDs or resistance inputs and 4 thermocouple or current or voltage inputs. The module is equipped with 9 green status indicators. These are used to establish the status for each of the channels and for the whole module status. The 1746sc-NI8U needs 5 Volts DC and 24 Volts DC power supplies. It is power supplied over the SLC-500 chassis. The maximum current drawn by this analog input module is 0.12 Amps at 5 Volts DC and 0.1 Amps at 24 Volts DC. The operating temperature range of the device is 0 to 60 degrees Celsius (32 to 140 degrees Fahrenheit). The module can be installed in any slot of an SLC-500 chassis except for slot 0 which is used for PLC processors. Users can connect one 16 AWG size wire or two 22 AWG sized wires to each of the terminals. The device is UL and CUL certified and it is CE compliant.
