GE IC693ALG221LT Analog Input, Current, 4 Channels (LT)

The RPS Baseplate should be grounded in the same manner as any IC693 PLC baseplate. Each ground

wire should consist of a size 12 AWG or larger wire with a ring terminal crimped to each end. One end

of each ground wire should be securely fastened to a conductive surface on the mounting panel (this often

requires removing the paint from the panel at the spot where the ground wire is fastened). If all ground

wires are connected to one point, ensure that the method (typically using a stud, nuts, and lock washers) is

approved by applicable electrical codes. 

The next figure shows an example ground connection for each

of the following components:

· RPS Baseplate and PLC Baseplate. One end of the ground wire should be mounted under the

head of the mounting bolt (with star lock washer and flat washer) in one of the baseplate’s

slotted mounting holes; the other end should connect to the grounding point on the panel.

· RPS Adapter Module. The RPS Adapter’s ground wire is supplied as part of the RPS cable.

See the section “IC693ACC350 Redundant Power Supply Adapter” for details and a picture of

this wire. Connect it to the grounding point on the panel.

Mounting Hardware

Tap four 8#-32 (4mm) holes in the mounting panel using the hole spacing shown in the following figure.

Use four #8-32 (4mm) machine screws with flat washers and lock washers in the baseplate mounting

holes. Mounting hardware should be a high quality, corrosion-resistant type. As shown in the following

figure, two baseplate holes are slotted in order to facilitate a ground wire connection (see “Grounding the

RPS System” on the following page).

Ventilation Clearance

As shown in the following figure, a minimum clearance allowance (open area) on all sides of the

baseplate is required to provide adequate ventilation.

Mounting Orientation

The baseplate is rated for full load output at 60°C (140°F) when mounted to a vertical surface and with its

long dimension oriented horizontally. This orientation provides best ventilation for the power supplies.

Mounting the baseplate in a different orientation results in the following load derating:

· For 25°C (77°F) temperature – full load

· For 60°C (140°F) temperature – 50% of full loadGrounding the RPS System

There are two models of RPS

Baseplates, which are identical except for the length of the adapter connection cable. 

The IC693ACC340 has a 0.125-meter cable, and the IC693ACC341 has a 0.6-meter cable.

Redundant Power Supply Adapter The Redundant Power Supply Adapter plugs into a

standard IC693 PLC baseplate’s power supply slot. 

It has a connector that mates to the RPS Baseplate’s adapter connection cable. 

It also contains the backup battery and serial port connector for the PLC (backup battery and

serial port connector are not functional on the individual power supplies).

We have the same series of models in stock.
