GE IC693ACC400 Expanded battery backup for Series 90-30 CPUs

The IC693 Redundant Power Supply System consists of a Baseplate and an Adapter, described below.

Redundant Power Supply (RPS) Baseplate The Redundant Power Supply Baseplate

has slots for two standard IC693 power supplies, an attached adapter

connection cable that connects to the Power Supply

Adapter, status LED lights, a 24VDC user output, and status relay outputs. 

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).

Auxiliary I/O Wiring and Functional Descriptions

The Auxiliary I/O connector includes a number of diverse signals used to interface the S2K

controller to your motion controller and machine. The functions available include:

• Analog Command Input (AI1)

• Torque Limit Analog Input (AI2)

• Analog Output (AO)

• +5 Vdc Output (for auxiliary encoder) (on the Pulse Input on SSI216. SSI228. & SSI420 models)

• +12 Vdc Output (for Enable input)

• Enable Input

• OK Output

• Encoder Output

• Auxiliary Encoder Input (on the Pulse Input on SSI216. SSI228. & SSI420 models)

The SSI216. SSI228. & SSI420 models have a different configuration for the Discrete I/O

and Auxiliary I/O connections as shown on the connection diagrams in Section 3.6.10.

The Enable input and OK output may be wired for either sinking or sourcing operation. The

operational voltage range is 12 to 24 volts DC. The OK output can sink or source 100 mA

maximum. The wiring to the Auxiliary I/O connector should be of appropriate size and

insulation quality for the application. To meet the requirements of EN61000-4-5 and CE

mark, Auxiliary I/O cables shall be shielded and shall not exceed 30 meters in length.

We have the same series of models in stock.
