SSI Servo Module
(Catalog Number 1756-M02AS)
The Synchronous Serial Interface (SSI) Servo Module mounts in a
ControlLogix™ chassis and uses a removable terminal block (RTB) to
connect all field-side wiring.
Before you install your module you should have:
• installed and grounded a 1756 chassis and power supply.
• ordered and received an RTB and its components for your
application.
