The Omron CJ1W-OD213, also cataloged as the CJ1W-OD213 Transistor Output Unit, operates as a dedicated hardware component for high-speed sinking discrete load switching within CJ Series backplane architectures.

Functional Circuitry & Interface Mapping

• Output Density: Contains 16 discrete output channels wired across a single common circuit (16 points/common).
• Switching Logic: Configured for sinking (NPN) switching operations rated at 24 VDC load voltages.
• Response Characteristics: Delivers rapid switching performance with a maximum ON response time of 15 us and OFF response time of 80 us.

Operational Parameters

Deterministic Network Bus Sync

Discrete output bit transitions synchronize directly to the CPU backplane via optimized backplane bus communication velocity Licences. High-speed output switching operates without added processing overhead, supporting rapid physical actuation cycles. Hardware flash compatibility and stable backplane mapping maintain consistent signal updates across expanded CJ Series rack layouts.

Mechanical Mounting & Field Wiring Directives

• Rack Installation: Align module slots with the CJ Series backplane standard rack rail and press firmly until locking clips engage fully.
• Auxiliary Power Supply: Wire an external 24 VDC (20.4 to 26.4 VDC) power supply providing at least 55 mA to the dedicated external power terminals.
• Load Connections: Wire NPN field loads to output terminals; ensure total load current does not exceed 0.5 A per point or 5.0 A total across the module.
• Chassis Grounding: Secure a low-impedance ground wire from the GR terminal to protective earth (100 ohm max resistance) to satisfy insulation testing parameters.

Technical Questions & Answers

• What switching type is implemented on the output channels of this module?

  The module utilizes NPN sinking transistor outputs where connected loads switch to the negative supply rail when active.

• What are the individual point and total module load current limits?

  Each output point carries a maximum load of 0.5 A, while total simultaneous current across the entire 16-point module must not exceed 5.0 A.

• Is internal fuse protection built into the output circuits?

  No internal fuses are integrated into the output circuits; external current-limiting protection or inline fusing should be installed per circuit.

• What are the ON and OFF switching speeds of the output transistors?

  The NPN output transistors feature an ON response time of 15 us max. and an OFF response time of 80 us max.

• What external power source is necessary for proper module operation?

  An external 24 VDC power supply operating between 20.4 and 26.4 VDC with a minimum current capacity of 55 mA is required.

• How much current does this card draw from the internal 5 VDC backplane?

  The internal logic circuitry draws a maximum current of 150 mA from the internal 5 VDC backplane bus rail.

• What is the maximum peak inrush current capability per output point?

  Each output channel can tolerate a maximum surge inrush current of 4.0 A for a duration up to 10 ms.

• Can this module be hot-swapped while backplane power is active?

  No, active rack power and external 24 VDC power must be isolated before removing or inserting the unit to prevent hardware faults.
