6 MicroLogix™ 1200 Isolated Relay Output Module
Use DIN rail end anchors (Allen-Bradley part number 1492-EA35 or 1492-EAH35)
for environments with vibration or shock concerns.
TIP
Panel Mounting
Use the dimensional template shown below to mount the module. The preferred
mounting method is to use two M4 or #8 panhead screws per module. M3.5 or #6
panhead screws may also be used, but a washer may be needed to ensure a good
ground contact. Mounting screws are required on every module.
For more than 2 modules: (number of modules - 1) x 40.4 mm (1.59 in.)
