Product Details

1336‑B003‑EOD‑L1 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 L1 +5V DC TTL‑level logic 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 L1 option adds expanded +5 V DC TTL‑compatible discrete digital inputs and relay outputs. These +5V logic‑level channels are intended for interfacing with TTL‑based PLC or sensor hardware; supports additional equipment interlock logic, external status feedback, multi‑source dry‑contact command signals. Different from 24V‑level L2 and encoder‑interface L3 option boards. 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 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 extra +5V TTL‑logic interlock I/O, and uses external HIM for operation and parameter setup.

Remark:Legacy EOL complete drive unit;original production discontinued;please confirm motor rating, +5V TTL signal‑level requirement, input voltage, cabinet‑installation dimension and option function matching before purchase.
