Product Details

1336‑B003‑EOD‑L2 is factory‑optioned IP00 open bare‑chassis 3‑HP 460V 1336‑PLUS AC drive, not separate PCB boards. Based on base model 1336‑B003‑EOD, factory pre‑installed L2 enhanced mixed analog‑digital I/O expansion board, without local HIM operator panel. This is open‑frame unit without outer protective housing and shall be installed in user‑supplied cabinet.

The L2 option is enhanced mixed‑signal expansion hardware, compared with basic L1 +5V TTL I/O board. Besides extra 24V discrete digital inputs and relay outputs, it adds analog input and analog output channels. It enables multi‑speed preset selection, external process variable signal collection, complex interlock logic for multiple field devices. It is widely used for process‑oriented equipment requiring both digital interlock and analog signal acquisition. No local keypad is fitted, external HIM accessory is mandatory for on‑site debugging and parameter editing.

Internal hardware integrates rectifier power stack, inverter IGBT power section, main control CPU board, auxiliary power supply, sampling and signal‑conditioning circuits. Supports sensorless vector and V/F control for standard three‑phase induction motors. Retains standard onboard analog/digital hard‑wired base I/O terminals for local hard‑wired start‑stop and speed reference.

Full protection suite: over‑current, over‑voltage, under‑voltage, over‑temperature, input phase‑loss, motor thermal overload, ground‑fault protection. Used for full‑unit replacement when multiple internal assemblies suffer compound damage. When swapping complete drive, back‑up original parameters, verify firmware compatibility and complete motor auto‑tuning. Shielded cables shall be adopted for analog and I/O wiring; strictly separate power cable and signal cable routing. Strict ESD protection required for installation and commissioning.

Typically applied for overhaul of legacy fans, pumps, general conveyors and workshop processing machinery. The drive is mounted inside existing control cabinet, requires enhanced mixed analog‑digital I/O for process control, and uses external HIM for operation and parameter setup.

Remark:Legacy EOL complete drive unit;original production discontinued;please confirm motor rating, 24V signal‑level requirement, analog signal range, input voltage, cabinet‑installation dimension and option function matching before purchase.
