1746-NOI4I Analog Output Module
The 1746-NOI4I is an SLC 500 Analog Output Module. This Analog Output Module has Four (4) Current outputs channels that provides output range of 0 to +20 mA. This module is used with SLC 500 fixed or modular style hardware.
This module is capable of producing an output Current range of 0 to 20 mA that may be used to drive modulating instruments and devices. Typical analog outputs are connected to a controller's control command. If used with a Proportional-Integral-Derivative controller, the analog output is assigned to represent the Control Output (CO) of the PID controller. For manual loading stations, the analog output represents the manual command entered by the operator. It may also be used to re-transmit an important signal to a single or multiple device. This may be for the purposes of indication, data logging and signal conversion.
