Product Overview

1756-OA16 is an Allen-Bradley ControlLogix 1756 AC digital output module for chassis-based industrial control systems.

Rockwell Automation specifies 16 outputs in two groups of eight, a 120/240 VAC 50/60 Hz category and a 74-265 VAC operating range.

The module includes one mechanical fuse and fuse indicator per group, diagnostic time stamping and a 20-pin removable terminal block interface.

Features

Sixteen AC outputs

Two groups of eight outputs support 120/240 VAC industrial loads within the 74-265 VAC operating range.

Group fusing

Each eight-point group has one mechanical fuse and a dedicated fuse indicator.

Published surge capacity

The module supports the specified 43 ms point and group surge currents for controlled AC load switching.

Diagnostic timing

Fuse diagnostics carry a published time-stamp accuracy of +/-1 ms.

Wiring

Field wiring	Use a 1756-TBNH or 1756-TBSH 20-pin removable terminal block housing; order the RTB separately.
Output group 0	Connect OUT-0 through OUT-7 with the L1-0 and L2-0 group supply terminals according to the official diagram.
Output group 1	Connect OUT-8 through OUT-15 with the L1-1 and L2-1 group supply terminals according to the official diagram.
Backplane	The module draws 400 mA at 5.1 V and 2 mA at 24 V from the ControlLogix backplane.

Installation

01 - Verify the complete catalog number

Match 1756-OA16 on the quotation, module label, packaging and Rockwell Automation product record.

02 - Confirm load compatibility

Verify 74-265 VAC at 47-63 Hz, minimum 10 mA load and the point, group and module current limits.

03 - Select the RTB

Choose 1756-TBNH or 1756-TBSH for the 20-pin field connection and key the RTB mechanically.

04 - Wire the two groups

Keep group 0 and group 1 line and load wiring aligned with the official L1, L2 and output-terminal diagram.

05 - Coordinate fusing and enclosure

Evaluate the group fuse, surge current and branch protection, then install the open-style module in a suitable industrial enclosure.

FAQ

Q1. How can the exact quoted 1756-OA16 be verified?

Match 1756-OA16 on the quotation, module label and packaging. Confirm 16 outputs, two mechanically fused eight-point groups, the 74-265 VAC range and the 20-pin RTB interface.

Q2. How can New, Used or Refurbished condition be distinguished?

Request date-marked photos of the full label, serial and series markings, 16 output indicators, both fuse indicators, RTB connector, backplane connector and housing. Check for fuse replacement marks, discolored terminals, altered labels or repaired plastic.

Q3. How should supplier legality and reliability be checked?

Verify the supplier legal entity, registered address, invoice details, payment beneficiary and traceable contact. The offer must identify Allen-Bradley, 1756-OA16, condition, quantity and whether the 20-pin RTB and fuses are included.

Q4. Which specifications must engineering confirm before purchase?

Confirm 74-265 VAC at 47-63 Hz, 0.5 A per point, 2 A per group, 4 A per module, 10 mA minimum load, surge-current limits, two-group wiring, 1756-TBNH or 1756-TBSH RTB and chassis backplane capacity.

Q5. What physical evidence should be requested before payment?

Ask for date-marked photos showing the full 1756-OA16 label, serial and series markings, output and fuse indicators, 20-pin RTB connector, backplane edge connector, housing condition, fuse areas and packaging.

Q6. Can 1756-OA16I, 1756-OA8 or 1756-OA16K replace 1756-OA16?

Not automatically. The isolated, eight-point and conformal-coated variants differ in channel arrangement, RTB, load capacity, wiring and environmental construction. Confirm the exact electrical and installation requirements before substitution.
