Technical Specifications Model: GLB0201 Signal Type: 24 V DC digital input and digital output Channel Configuration: Mixed DI / DO channels Interface: Screw‑clamp terminal block, wire range 0.2‑2.5 mm² Mounting Mode: TS35 DIN‑rail mounting Power Supply: 24 V DC Galvanic Isolation: 500 V AC field‑to‑logic side isolation Operating Temperature: 0 ℃ to +60 ℃ Storage Temperature: ‑40 ℃ to +85 ℃ Relative Humidity: 5‑95 %, non‑condensing Protection Class: IP20 Certifications: CE
Functional Features Mixed digital input and output channels realise field discrete signal wiring termination. Built‑in over‑current protection components safeguard back‑plane I/O modules against field loop faults. Signal filter circuit suppresses high‑frequency electromagnetic interference from field cables. Group‑wise galvanic isolation eliminates ground‑loop disturbance between field equipment and control system. Front‑panel LED status indicators show real‑time signal status for each channel. Compact DIN‑rail mounting structure facilitates cabinet layout and spare‑part replacement.
Application Scenarios Spare‑part replacement for GLB0201 terminal module inside industrial control cabinet. Signal termination for limit switches, proximity sensors, intermediate relays and solenoid valves. Discrete signal loop protection for chemical, power and manufacturing automation cabinets.
Working Principle Field 24 V DC discrete input signals enter GLB0201 through front screw‑clamp terminals, pass through protection and filter circuits, and go through optocoupler isolation before transmitting to control I/O modules. Output control signals from I/O modules pass isolation circuit and drive external field loads. LED indicators light up when corresponding channel has valid signal state. Protection components cut off fault loop immediately once field‑side over‑current occurs to protect system I/O hardware.
Installation Requirements Clip GLB0201 firmly onto TS35 standard DIN‑rail inside control cabinet. Connect field device cables to front screw‑clamp terminals and tighten terminals to specified torque. Use dedicated connecting cable to link GLB0201 with corresponding control I/O module. Implement protective earthing complying with system grounding specification.
