Specifications and Supplemental Information
Encoder Interface Wiring
Option L4/L4E & L7E Wiring
Option L4/L4E - Contact Closure Interface Board Requirements
Contacts must be capable of operating at 10 mA current levels
without signal degradation. Reed type input devices are recom-
mended.
The L4/L4E option is compatible with the following Allen-Bradley
PLC
modules:
• 1771-OYL
• 1771-OZL
Option L7E - Contact Closure Interface Board Requirements
Circuits used with Option L7E must be capable of operating with
low = true logic. In the low state, external circuits must be capable of
a sinking current of approximately 10 mA to pull the terminal voltage
low to 3.0V DC or less. In the high state, external circuits must let the
terminal voltage rise to a voltage of 4.0-5.0V DC. Reed type input
devices are recommended.
The L7E option is compatible with the following Allen-Bradley
PLC
modules:
• 1771-OYL
• 1771-OZL
