PRODUCT INFORMATION
Product Overview
The Allen-Bradley 1746-IC16 is an SLC 500 Current Sinking DC Input Module. This module provides 16 current sinking inputs designed for 48V DC nominal circuits. It uses a removable terminal block for field wiring connections. The module operates with a backplane current draw of 85 mA at 5V DC. Backplane current draw at 24V DC is 0 mA.
The operational voltage range is 30 to 60V DC sinking at 55 °C. At an operating temperature of 60 °C, the voltage range is 30 to 55V DC. Each input point exhibits a maximum signal delay of 4 milliseconds for both states. Isolation between the backplane and field inputs is rated at 1500V AC. The module operates within an ambient temperature span of 0 to 60 °C.
