Allen Bradley 1756-OB16IS Digital DC output module with individual isolation and scheduled outputs

FAQ

Q1: What is the purpose of the 1756‑OB16IS module?
It provides 16 individually isolated DC output channels with scheduling support for controlled switching in industrial automation.

Q2: What DC voltage range does this module support?
The outputs operate over approximately 10 – 30 V DC with a nominal 12/24 V category.

Q3: How much current can each output deliver?
Each output channel is rated for 1 A continuous, with pilot duty up to 2 A at ~30 °C.

Q4: What is output isolation capability?
The module offers ~250 V continuous isolation between output channels and the backplane.

Q5: How many outputs are scheduled?
8 of the 16 outputs can be synchronized with coordinated system time for scheduled switching.

Q6: What are the typical backplane power requirements?
It draws about ~350 mA at 5.1 VDC and ~2.5 mA at 24 VDC from the backplane.

Q7: What are the typical output delay times?
OFF→ON delay is up to ~1 ms and ON→OFF delay up to ~2 ms.

Q8: What are the physical size and weight of the module?
It measures about 300 mm × 38.1 mm × 111.25 mm and weighs around ~0.20 kg.
