1. General Information

• Part Number: 0-49061 (also referenced as 49061)

• Manufacturer: Reliance Electric (Rockwell Automation)

• Product Type: CardPak Series Square Wave Generator Module

• Function: Generates precision square-wave timing/clock signals for Reliance drive control & synchronization

• Status: Obsolete / legacy; available as new surplus, refurbished, or used

• Application: FlexPak 104/105, CardPak-based DC drives, motion control systems, process line synchronization

2. Specifications

2.1 Electrical

• Output Waveform: Precision square wave, 50% duty cycle

• Frequency Range: Adjustable, typically 10 Hz – 10 kHz (via onboard pot)

• Output Levels: TTL-compatible (5 VDC) or ±12 VDC (selectable)

• Drive Compatibility: FlexPak 104/105, CardPak chassis (115/230 VAC supply)

• Isolation: Opto-isolated outputs (1500 VACrms) for noise immunity

• Power: 115/230 VAC (drive internal power supply)

• Protection: Overvoltage, short-circuit, ESD protection

2.2 Mechanical

• Form Factor: Standard CardPak plug-in PCB

• Dimensions: 190 mm × 120 mm × 30 mm

• Mounting: Inserts into CardPak chassis slot (edge connector)

• Connectors: Edge connector (signal/power), screw terminals for field wiring

• Adjustments: Onboard potentiometer (frequency), DIP switches (level/termination)

3. Features

• Precision Timing: Stable square-wave clock for drive sequencing & synchronization

• Adjustable Frequency: User-tunable output frequency via front-panel pot

• Dual Output Levels: Selectable TTL or ±12 VDC to match system I/O

• Opto-Isolation: Eliminates ground loops; improves noise rejection

• Plug-and-Play: Direct replacement for original 0-49061 in CardPak slots

• Synchronization: Aligns multiple drives for coordinated motion (conveyors, lines)

4. Installation

1. Power OFF: Disconnect all AC power to the drive/chassis.

2. Access Chassis: Remove cover to expose CardPak slots.

3. Insert Module: Align 0-49061 with slot; push firmly until edge connector seats.

4. Field Wiring:

   • Output: Terminate square-wave signal to target drive/controller I/O

   • Power: Connect to chassis 115/230 VAC (as labeled)

5. Configuration:

   • Set output level (TTL / ±12 VDC) via DIP switch

   • Adjust frequency via onboard potentiometer

6. Restore Power: Apply AC power; verify output with oscilloscope (no fault LEDs).

5. Troubleshooting

• No Output Signal: Check power wiring, edge connector seating, DIP switch setting.

• Unstable Frequency: Verify chassis grounding, shielded cables, or potentiometer wear.

• Incorrect Output Level: Confirm DIP switch matches expected TTL/±12 VDC.

• Module Not Detected: Reseat board; inspect edge connector for dirt/damage.

6. Availability & Warranty

• New Original: Discontinued by Reliance Electric.

• Supplied As: Refurbished (fully tested), used (working pull), or new surplus.

• Warranty: Typically 12 months (refurbished); 30–90 days (used)

7. Replacement Notes

• Direct Replacement: 0-49061 is the only OEM drop-in for CardPak square wave generator slot.

• Cross Reference: No modern equivalent; use original/refurbished module for legacy systems.
