1746-IB8 Allen Bradley

1746-IB8 Allen Bradley

SLC 500 Digital DC Input Module by Allen-Bradley is a DC input module in the SLC 500 I/O module series with eight 24V DC current sinking inputs. The 1746-IB8 has an operational voltage range between 10 and 30V DC with its nominal voltage at 24V DC and it has a backplane current of 50mA at 5V DC and of 0.0mA at 24V DC.

Features:

• The maximum signal delay time on each input point of the module is about 8ms for ON mode
• 8ms for OFF mode, and the maximum OFF state voltage in the circuit is 5.0V DC.
• Maximum OFF-state current of 1mA, and when operational, its nominal input current is 8mA at 24V DC. 
• Maximum of 0.27W power dissipation on each output point and the total heat dissipation of the module is 1.3W with 4.4 BTU per hour of thermal dissipation.
• Dielectric withstand of 1500V AC and an isolation between the communication circuits tested at 500V and between backplane-and-inputs at 1500V AC.
