Products Description
OPTIMATION OL4228 OptiLogic RTU Base

Module Feature
OPTIMATION OL4228 belongs to OptiLogic series 8-slot remote terminal unit base. It supplies 8 standard hot-pluggable slots for OL series I/O modules. Integrated 10BaseT Ethernet communication supporting OptiLogic/UDP protocol. Internal backplane distributes power and high-speed data bus for all inserted I/O cards. DIN rail mounting metal housing, suitable for mixing analog input, digital input, relay output and serial communication modules. Widely used for semiconductor wet bench and chemical fluid delivery distributed control cabinets.
Working principle: The backplane provides power and communication bus for each installed I/O module. It collects field sensor data from I/O cards, transmits data to host controller over Ethernet, and receives host commands to drive field actuators. Onboard components: Main control logic PCB,10BaseT Ethernet circuit, 8 module slots, DC power terminal block, metal DIN rail housing, backplane edge connectors, front panel status LEDs
LED indicatorsPower, Ethernet link and rack fault LED indicators on front panel
Hardware self-diagnosis

Function
OL4228 RTU base manufactured by OPTIMATION. It is 8-slot distributed I/O rack to expand process signal points. Poor backplane contact or incorrect Ethernet IP settings will cause module offline and signal loss. It is core remote I/O chassis for wet process automation control cabinet.
Installation
Follow lockout/tagout safety procedure before installation. Power off OptiLogic RTU rack. Mount chassis on DIN rail. Insert I/O modules into empty slots and lock latches. Wire 8-30VDC power and Ethernet cable. Configure network parameters and test all I/O channels before production startup.
InterfaceDC power terminal block, 10BaseT Ethernet port, OptiLogic backplane slot connectors, power/link/fault LED indicators on housing of OL4228.
Diagnostic
No Ethernet link:IP address mismatch or cable fault. Module undetected:Damaged edge connector or poor backplane contact. Intermittent I/O signals:Vibration causing loose module seating. Rack power alarm:Overload or loose power wiring.
