PRODUCT INFORMATION
Product Overview
The Allen-Bradley 1746-ITV16 is an SLC 500 fast response discrete input module. This module provides 16 fast-response discrete input points for industrial control systems. It operates across a voltage range of 10 to 30 VDC with a 24 VDC nominal rating. The module uses a source wiring configuration for connected sensing hardware.
The 1746-ITV16 delivers maximum signal delays of 0.3 milliseconds for ON and 0.5 milliseconds for OFF transitions. Internal filter circuitry and optical coupling reduce electrical noise across the input circuits. Backplane current consumption measures 85 milliamps at 5 VDC and zero milliamps at 24 VDC. A removable terminal block allows field wiring maintenance without disconnecting individual field conductors.
