ATTENTION

Preventing Electrostatic Discharge

This equipment is sensitive to electrostatic

discharge, which can cause internal damage and

affect normal operation. Follow these guidelines

when you handle this equipment:

• Touch a grounded object to discharge potential

static.

• Wear an approved grounding wriststrap.

• Do not touch connectors or pins on component

boards.

• Do not touch circuit components inside the

equipment.

• If available, use a static–safe workstation.

• When not in use, keep modules in appropriate

static–safe packaging.

The Series B 1771-OVN dc output module is a sink output and

requires a source input. A source input provides a positive voltage

path and a sink output provides a path to ground.

You must use this module in a 1771-A1B, -A2B, -A3B, -A3B1,

-A4B or later 1771 I/O chassis. Refer to the table below for

processor compatibility.

Local MiniĆPLCĆ2/02 (cat. no. 1772ĆLZ, ĆLZP)

MiniĆPLCĆ2/16 (cat. no. 1772ĆLX, ĆLXP)

MiniĆPLCĆ2/17 (cat. no. 1772ĆLW, ĆLWP)

PLCĆ5/15, Series B and later (cat. no. 1785ĆLT)

Remote (with a 1771ĆASB

remote I/O adapter)

PLCĆ2/20 (cat. no. 1772ĆLP2)

PLCĆ2/30 (cat. no. 1772ĆLP3)

PLCĆ3 (cat. no. 1775ĆL1, ĆL2, ĆL3, ĆL4)

PLCĆ3/10 (cat. no. 1775ĆLP4, ĆLP8)

PLCĆ5/15, Series B and later (cat. no. 1785ĆLT)

Do not place this module in the same I/O chassis as the 1771-IX

thermocouple module. You can use this module in the same chassis

as the 1771-IXE thermocouple module.

The controller or I/O chassis power supply, connected through the

backplane of the I/O chassis, powers the logic circuitry of the output

modules. The maximum current drawn from this supply is 330mA.
