PLA-21 PLA-21 Power Line Amplifier Model 53001-01 M Capable of transmitting a 10V p-p signal with 2A p-p current drive M UL, CSA, TÜV recognized Description The LONWORKS PLA-21 PLA-21 Power Line Amplifier is designed to boost the output level of a PLT-22 PLT-22 Power Line Transceiver. The boost function is intended for commercial and industrial ® applications in high rises, manufacturing plants, utility substations, and other large facilities. Capable of transmitting a signal of 10V peak-to-peak (p-p) with 2Ap-p current drive, the PLA21 PLA21 amplifier is ideal for driving multiple-phase coupling circuits, high attenuation power circuits, and very low impedance loads near circuit breaker panels and distribution transformers. The PLA-21 PLA-21 amplifier consists of a single in-line package (SIP) containing the amplifier circuitry and connector pins (actual appearance may differ from photo). PLA-21 PLA-21 AMPLIFIER PINOUT The table which follows lists the functions of the PLA-21 PLA-21 amplifier pins. Pin # Pin Name Function 1 HS1 Heat sink connection (leave floating) 2 ILIM1 1A/2A TX current limit control pin 3 VA 15VDC 15VDC power supply 4 TXIN Transmit signal input from PLT-21 PLT-21 (TXOUT pin) 5 VA 15VDC 15VDC power supply 6 TXON Transmit enable signal from PLT-21 PLT-21 (CLKSEL1/TXON pin) 7 GND Ground 8 TXOUT Transmit signal output to line coupling circuit 9 TXOUT Transmit signal output to line coupling circuit 10 GND Ground 11 RXSUM TXOUT buffered by 650. (leave floating) 12 GND Ground 13 GND Ground 14 ILIM2 1A/2A TX current limit control pin 15 HS2 Heat sink connection (leave floating) Pins 8 and 9 are connected internally, but should always be connected externally as well. Shorting ILIM1 (pin 2) and ILIM2 (pin 14) to TXOUT (pins 8 and 9) places the PLA-21 PLA-21 into 2A p-p output current limit mode. Leaving pin 2 and pin 14 open places the PLA-21 PLA-21 in 1A p-p output current limit mode. Pin 11, RXSUM, is for special applications where separate TXOUT and RXIN signals on the PLT-22 PLT-22 transceiver are not available. This pin should be left floating. HS1 (pin 1) and HS2 (pin 15) are connected to the collectors of the respective output power transistors and to the heat sink copper areas of the PLA-21 PLA-21 amplifier. Pin 1, pin 15, and the heat sink areas should always be left floating.
