The ac isolated output module is shipped in static-shielded packaging

to guard against electrostatic discharge damage. Observe the

following precautions when handling the module.

Electrostatic Discharge Damage

ATTENTION: Electrostatic discharge can damage

integrated circuits or semiconductors if you touch

backplane connector pins. Follow these guidelines

when you handle the module:

• Touch a grounded object to discharge static potential

• Wear an approved wrist-strap grounding device

• Do not touch the backplane connector or

connector pins

• Do not touch circuit components inside the module

• If available, use a static-safe work station

• When not in use, keep the module in its original

static-shielded packaging

AC (120V) Isolated Output Module, 16 Outputs European Union Directive Compliance If this product has the CE mark it is approved for installation within the European Union and EEA regions. It has been designed and tested to meet the following directives.
PAGE 3
AC (120V) Isolated Output Module, 16 Outputs 3 The switching device in the output circuit is a solid-state triac. There is a small leakage current in the off state due to both triac and capacitive characteristics. The maximum leakage current per output is 3mA at 138V ac. Nominal leakage current is 1.5mA. The on-state voltage drop across the output terminals will not exceed 1.5V ac at 2A. The 1771-ODD/B module is designed for a 10mA minimum current on each output circuit.

AC (120V) Isolated Output Module, 16 Outputs ! ATTENTION: Remove power from the 1771 I/O chassis backplane and wiring arm before removing or installing an I/O module. • Failure to remove power from the backplane or wiring arm could cause module damage, degradation of performance, or injury. • Failure to remove power from the backplane could cause injury or equipment damage due to possible unexpected operation.

AC (120V) Isolated Output Module, 16 Outputs To change the fuse blown jumper to the CSI mode: 1. Locate the fuse-blown jumper at the top-right edge of the module circuit board, as shown in the following figure. TopĆright edge of circuit board STD CSI Fuse Blown Jumper (shown in preset STD position) 12636ĆI 2. Use your finger to slide the jumper off the STD position (the middle post and the left post). 3.

AC (120V) Isolated Output Module, 16 Outputs Install the Module and Field Wiring Arm ! ATTENTION: Remove power from the 1771 I/O chassis backplane and field wiring arm before removing or installing an I/O module. • Failure to remove power from the backplane or wiring arm could cause module damage, degradation of performance, or injury. • Failure to remove power from the backplane could cause injury or equipment damage due to possible unexpected operation.
PAGE 7
AC (120V) Isolated Output Module, 16 Outputs Connect the Wiring to the Field Wiring Arm 7 You make connections to the module through the 1771-WN field wiring arm shipped with the module. The arm pivots on the chassis to connect with the terminals on the front of the module (as shown below). The wiring arm allows the module to be removed from the chassis without disconnecting wiring. 1. Make certain all power is removed from the module before making wiring connections. 2.

AC (120V) Isolated Output Module, 16 Outputs Note: You can use the shorting bar supplied with your module to connect the L1-0 through L1-17 high side ac power connections together if no isolation is required. You should identify the labels on the wiring arm with the name or number of the device connected at each terminal.

AC (120V) Isolated Output Module, 16 Outputs Interpreting the Status Indicators The module has 32 status indicators and 1 active indicator. The 16 indicators on the left side of the display show the state of each output and are driven by the logic circuitry on the programmable controller side of the module. These indicators light when their corresponding outputs are energized.

AC (120V) Isolated Output Module, 16 Outputs Replacing a Fuse Each module output is individually fused. You can easily access the module fuses through the access holes on the side cover. Follow the procedure below. ! ATTENTION: Remove power from the 1771 I/O chassis backplane and wiring arm before removing or installing an I/O module. • Failure to remove power from the backplane could cause injury or equipment damage due to possible unexpected operation.
