Constat - Allen-Bradley 2094-AL15S Installation Instructions Manual

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

24V Power Supply
(catalog numbers 2094-ALxxS, 2094-BLxxS, and 2094-XL75S-Cx)
The 24V DC power supply on 2094-ALxxS, 2094-BLxxS, and 2094-XL75S-C2
line interface modules is capable of supplying +24V @ 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
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.
Use the P1L +24V DC supply with devices that can potentially generate flyback

currents (for example, brake coils and relays).
