1746-IO8 | Allen-Bradley SLC 500 Combination Module 4-Input 120VAC 4-Relay N.O.

Description 

The Allen-Bradley SLC 500 series 1746-IO8 I/O module is equipped with both input channels and output channels for flexible operation in different industrial systems. It is designed to operate in any industrial environment that is not hazardous, and to operate in Class 1, Division 2, Groups A, B, C, and D rated hazardous industrial environments. The 1746-IO8 input and output module should not be exposed to certain kinds of chemicals because it is a relay contact module with a protective seal that can be degraded by harsh chemicals. It is important to inspect the module periodically for wear and tear, especially if it is being used in a hazardous environment. The 1746-IO8 input and output module has 4 inputs and 4 outputs.

Technical Specifications 

Information About 1746-IO8

The 1746-IO8 SLC 500 Digital Input/output Combined Module is a combined input and output module by Allen-Bradley and is fitted in any slot (except slot 0) of 1746 I/O chassis. It has four 120V AC inputs per module and 4 relay contacts outputs with 4 points per common. It has an operating voltage range (85-132V AC) similar to most members of the SLC 500 combined I/O modules and has an output rating of 5-65V AC and 5-125V DC at 47-53Hz. It draws a backplane current of 0.03A at 5V DC and 0.025A at 24V DC and has 0.27W heat dissipation on all input points and 0.133W heat across each output points. 

The module has an aggregate heat dissipation of 3W, and has 35ms and 45ms signal delay time on both the input and output ON and OFF states. The relay contact output has a Normally Open (N.O.) contact with a contact rating of 1.5A continuous current per point at 120V AC and 1.2A per point at 24V DC. The 1746-IO8 has a factory-specified operating temperature range between 0 and 60 °C (32 and 140 °F) at 5-95% humidity and it has a designated non-operational temperature range between -40 and 85 °C (-40 and 185 °F). It has an operational shock rating of 30G and is also tested to withstand a maximum operational vibration of 2.5G at 57-200Hz. It is CE, CSA, and C-UL-certified and provides NEMA standard ICS 2-230 rated noise immunity.
