Brake Power Supply
(catalog numbers 2094-AL09 and 2094-BL02)
A +24V DC supply is provided on the PSL connector of the 2094-AL09 and
2094-BL02 line interface modules for mechanical motor brakes and the Bulletin
2090 resistive-brake module I/O. The supply has over-current protection and is
isolated from all other supplies. A single-phase filter placed on the input to the
supply provides conditioning. The supply is protected by circuit breaker CB3.
The PSL brake power supply is rated at 2 A. If more current is required, consider
using the IOL power supply.

IMPORTANT
Use the PSL +24V DC supply with devices that can potentially generate flyback
currents (for example, brake coils and relays). This supply requires external flyback
protection with either a diode or MOV.
