PLC4000 SERIES 120 WATT DC-DC POWER SUPPLY FOR THE ALLEN BRADLEY 1771 PLC SYSTEM FEATURES • • • • Active Current Sharing Full Redundant Operation Hot Swap Capability Remote Sense Input Input Power: 215 watts max. Status Alarm: Signals PLC if input voltage drops below specified range. Transient Protection: Fuse and back to back zener diodes protect against catastrophic failure. Reverse Polarity Protection: Unit will not turn on if re- verse polarity is detected. Isolation: 725V for 1 minute, 850V for 1 second. Conditions: input to output and input to case. Output • • • • Monitor & Alarm Status Hold Up Time - 20mS Multiple Input Voltage Ranges Input & Output Protection General Description The lntronics’ PLC4xxx is an external DC-DC power supply designed to completely and safely power a fully loaded Allen Bradley 1771 PLC. The PLC4xxx can be operated in "stand alone" or "redundant mode" for high availability system configurations. The units mount externally to the 1771 PLC to maximize available I/O slots and provide up to 24 amps @ 5Vdc to power most standard 1771 PLC rack configurations. The units contain appropriate monitoring and alarm circuitry to interface with the 1771 PLC rack. In the event of input power failure, the units have sufficient hold up time to ensure orderly system shutdown. General Specifications Output Voltage: 4.87 - 5.25 Vdc (normal range for the 1771 PLC Size: 9" x 8" x 3.8" - Refer to figure 1. system, including noise and ripple.) Power supply and System Interface: Current Range (non-redundant): 2 A min., 24 A max. Current Range (redundant): 4 A min., 24 A max. Refer to fig. 2 for stand alone configuration. Refer to fig. 3 for redundant mode configuration. Remote Sense: Maintains accurate voltage at the PLC with Fuse: user accessible. recommended cable (up to 4 ft of 12 AWG wire). Input Cable: 14 AWG wire. Overcurrent: Unit will shutdown at 110-130% of rated output Output Cable: 12 AWG wire, 4 foot max. current. Reset by cycling power off for 15 seconds. LED Indicator: Input and output voltages are within specified limits when Overvoltage: Unit shuts down if output voltage exceeds 5.5 V. For illuminated. redundant configuration, range is 5.5 - 6.0 V. Safety Agency Approval: Pending (UUCSA/CE). Undervoltage: Provides status alarm. Turn on Time: 4 sec. max. to specified output range. Ripple: 35 mV max. p-p, ripple + noise: 50 mV max. p-p measured at the PLC power input (through 4’ cable). Load Sharing: Active load sharing is enabled in redundant configuration. Hold up Time: 20 mS min. after a 2 mS ride-through under worst case line and load conditions. Ordering Information Model Number Input Voltage PLC4024 20 – 32 Vdc (24 V nominal) PLC4048 40 – 62 Vdc (48 V nominal) PLC4125 90 – 145 Vdc (125 V nominal) Transient Load: Maintains specified operation for up to a 25% load change. Shutdown may result for transients greater than 25%. Status Output: Closed relay contact when outputs are within specified range. PE Output: Power good signal to the PLC 1771 rack.
