Allen Bradley 1756-OW16I Electromechanical relay output module

FAQ

Q1: What type of outputs does the 1756-OW16I provide?
It provides 16 electromechanical relay outputs with normally open contacts.

Q2: Can it switch both AC and DC loads?
Yes, it supports both AC (up to 265 V) and DC (up to 125 V) loads.

Q3: What is the current rating per output?
Each output channel is rated for approximately 2 A continuous current.

Q4: Are the outputs isolated?
Yes, each relay output is individually isolated for improved safety and flexibility.

Q5: What are the switching speeds of the relays?
Typical operate and release times are around 10 ms.

Q6: What is the expected relay life?
Mechanical life is around 10 million operations, while electrical life is about 100,000 operations depending on load.

Q7: Does the module require external power?
Yes, the external load supply is required since the module only switches the circuit via relay contacts.

Q8: What are the physical dimensions and weight?
The module measures about 300 mm × 38.1 mm × 111.25 mm and weighs approximately 0.40 kg.
