Technical Specifications Model: CMA135 Output Channel: Multi‑channel relay contact output Contact Rating: Industrial‑grade relay contact switching capacity Galvanic Isolation: Relay contact realizes complete isolation between control‑logic‑side and field‑load‑side Power Supply: Supplied by Synpol D rack internal back‑plane Operating Temperature: 0 ℃ to +60 ℃ Storage Temperature: ‑40 ℃ to +85 ℃ Relative Humidity: 5‑95 %, non‑condensing Mounting Type: Synpol D rack plug‑in terminal board Protection Class: IP20 Certifications: CE
Functional Features Receives digital‑output control commands from Synpol D main control board via rack back‑plane bus. Each channel adopts mechanical‑relay contact output, realizes complete electrical isolation between control‑system internal circuit and field‑load loop. Front‑panel LED status indicators display pull‑in‑release state of each output‑channel relay. Built‑in relay‑coil surge‑suppression protection components. Plug‑in rack‑mount board structure facilitates on‑site spare‑part replacement. Supports field‑site interlock circuit, solenoid‑valve and auxiliary‑equipment on‑off control.
Installation Requirements Align CMA135 board with Synpol D rack slot guide‑rail, insert board in place and lock board‑edge locking buckle. Connect field‑site load‑loop cables to front‑side screw‑type terminals, tighten terminals to specified torque value. Complete cabinet protective earthing complying with Synpol D system grounding specifications. Separate field‑load power‑cables and control‑signal cables. Reserve ventilation‑heat‑dissipation space around rack slot. Ambient operating temperature must stay within 0 ℃ ~ +60 ℃ without condensation.
Usage Notes Strictly comply with relay‑contact rated voltage and current‑carrying capacity limits; do not exceed contact load rating. For inductive‑load field‑loop, add external absorption‑circuit according to engineering requirement.
