OPTIMATION ICM2104 Relay Output Module

Module Feature

OPTIMATION ICM2104 belongs to OptiLogic series 4-channel mechanical relay output module. Each channel provides independent galvanic isolated dry contact relay, capable of switching AC and DC field loads. Each channel has dedicated front panel LED status indicator, equipped with removable screw terminal block. Standard OptiLogic form factor, supports hot-plug installation into OL4054, OL4058, OL4228 RTU racks. Widely applied to control solenoid valves, alarm buzzers and auxiliary contact signals in semiconductor wet bench and chemical delivery control systems.

Working principle: RTU backplane transmits on/off control signal to drive internal relay coil. Mechanical relay contact closes or opens to switch field side AC/DC load. Galvanic isolation separates field power circuit and rack internal control bus, protecting RTU mainboard from surge and interference. Onboard components:4 mechanical relay units, relay drive PCB, removable terminal block, backplane edge connector, front panel per-channel LED indicators

Function

ICM2104 relay output module manufactured by OPTIMATION. It switches AC or DC field loads by mechanical relay contacts. Inductive loads without surge suppression may cause relay contact burnout. It is compact discrete output component for wet process automation control rack.

Installation

Follow lockout/tagout safety procedure before installation. Power off OptiLogic RTU rack. Insert module into empty rack slot and lock latches. Wire field loads to removable terminal block, install surge suppressor for inductive loads. Test all 4 relay channels before production startup.

InterfaceField load removable terminal block, OptiLogic backplane edge connector, per-channel relay status LED indicators on housing of ICM2104.

Diagnostic

No relay action:Missing control signal or failed relay coil. Contacts cannot open:Contact welded by overload current. Intermittent output:Loose terminal screw connection. Module not detected:Poor backplane edge connector contact.
