The four auxiliary (safety) contacts (used in 2094-AL09 and 2094-BL02 line
interface modules) are volt-free, positively-guided, and mechanically-latched.

S, and 2094-XL75S-C2
line interface modules is capable of sup24V @ 20 A for PLC I/O
functions (IOL connector), mechanical motor brakes, and the Bulletin 2090
resistive-brake module (RBM) I/O (P1L connector). An AC line filter is placed
on the input to the supply to provide conditioning. The supply is protected by
circuit breaker CB3.
PLC I/O power is available to the user via the IOL (21-pin) terminal block
connector (as shown in the figure on
page 22
).
Motor brakes and the resistive-brake module I/O power is available to the user
via the P1L (6-pin) connector. Each P1L output contains an LC circuit to
prevent electrical noise contamination of the 24V supply and an MOV to prevent
current surges from the motor brake.

IMPORTANT
Use the P1L +24V DC supply with devices that can potentially generate flyback
currents (for example, brake coils and relays).
