The analog output module is sensitive to electrostatic discharge.

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

static-shield box

PAGE 2
Fast Isolated Analog Output Module Understand Compliance to European Union Directives 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
Fast Isolated Analog Output Module Determine Module Placement in the I/O Chassis 3 Place your module in any I/O module slot of the I/O chassis except for the extreme left slot. This slot is reserved for PC processors or adapter modules. ! ATTENTION: Do not insert or remove modules from the I/O chassis while system power is ON. Failure to observe this rule could result in damage to module circuitry. Group your modules to minimize adverse affects from radiated electrical noise and heat.
PAGE 4
Fast Isolated Analog Output Module 2 Key the Backplane Connector Place your module in any slot in the chassis except the leftmost slot which is reserved for processors or adapters. Position the keying bands in the backplane connectors to correspond to the key slots on the module. I/O chassis Place the keying bands: between 26 and 28 between 32 and 34 You can change the position of these bands if subsequent system design and rewiring makes insertion of a different type of module necessary.
PAGE 5
Fast Isolated Analog Output Module 4 Connect Wiring to the Remote Termination Panel 5 Remote Termination Panel (RTP) The 1897-NOV module is cable-connected to a 1771-RTP4 remote termination panel using cat. no. 1771-NC6 (6 ft) or -NC15 (15 ft) cables. This RTP has straight-through wiring. The remote termination panel mounts on standard DIN 1 or DIN 3 mounting rails. Each channel has four connections: R, I, O, and S. Field wiring to the RTP is the same for all RTP variations.

Refer to the following table for wire termination designations.
PAGE 7
Fast Isolated Analog Output Module Grounding Your Field Devices 7 When using shielded cable, ground the foil shield and drain wire only at one end of the cable. We recommend that you wrap the foil shield and drain wire together and connect them to the “S” connection on the RTP for the particular channel. All shield connections are internally connected together in the RTP so that only one wire is required to ground the entire remote termination panel.

Fast Isolated Analog Output Module Reading Data from Your Module 9 The digital status data resides in the modules Rack/Group/Slot location in the programmable controller input image table. The following table shows the format of the 16 bit data word read from the module over the backplane: Input Data Definition Dec.

Fast Isolated Analog Output Module At power-up, an initial module self-check occurs. The module checks: • correct RAM operation • EPROM operation • EEPROM operation The RUN/FAULT indicator will be green when the check is completed satisfactorily. It will flash green until the first valid block transfer write has been received. If a fault is found initially or occurs later, the RUN/FLT indicator turns red. After passing initial diagnostics, the module turns the RUN/FLT indicator to flashing green.
