Brand: Allen Bradley
Model No : 1746-IB32
Type: Digital DC Input Module
Price: $110.00
Description :
An SLC 500 discrete input module is the Allen-Bradley 1746-IB32. The voltage range for this module is 15-30V DC at 50 °C (122 °F) or 15-26.4V DC at 60 °C (140 °F), with a nominal value of 24VDC. Electrical components including switches, sensors, auxiliary contacts, and other binary or ON/OFF devices are frequently interfaced using this module. The 32 integrated input module channels may be used to connect up to thirty-two (32) input signals to this module.
Input
The 1746-IB32 features a maximum off-state input voltage of 5VDC, a maximum backplane current draw of 50 mA at 5VDC, a nominal input current of 5.1 mA at 24V DC, a maximum off-state input current of 1.5 mA, and a typical signal latency of 8 ms for both ON to OFF and OFF to ON signal transitions.
RIUP
As this module does not allow Removal and Insertion Under Power (RIUP), make sure to turn off the power before inserting the module. It has a detachable terminal block (RTB) that enables remote wiring to the module and simplifies maintenance by allowing insertion into another module of the same kind.
Rating
The 1746-IB32 has a 1500 Volt AC dielectric withstand and provides isolation from the backplane tested at 1500 Volts AC for 60 seconds between the backplane and the I/O. In its OFF state, it has a maximum voltage drop of 5.0 Volts DC and a maximum leakage current of 1.5 mA. The minimum voltage across its circuit in the ON state is 15.0 Volts DC.
The 1746-IB32 module has an overall nominal input current of 5.1 mA at 24 Volts DC nominal voltage and a maximum signal delay time of 3ms across its inputs in both the ON and the OFF mode. The working temperature range for the 1746-IB32 is 0 to 60 degrees Celsius (32 to 140 degrees Celsius) at 5 to 95% non-condensing humidity. It also has a shock rating of 30G and an operational vibration withstand of 1G at 5 to 200 Hertz.
