Watlow PM6L3EJ-1AAAAAA EZ-ZONE PM Universal Input Limit Controller with Relay Outputs and Modbus Communication

Description

Watlow PM6L3EJ-1AAAAAA is an EZ-ZONE PM limit controller that monitors a universal sensor input and operates relay outputs when configured process limits are exceeded. Its panel-mounted display and EIA-485 Modbus RTU interface support local supervision and communication with compatible industrial control systems.

Technical Specifications

Information About PM6L3EJ-1AAAAAA

The PM6L3EJ-1AAAAAA is a 1/16 DIN model within the Watlow EZ-ZONE PM family. Its configuration combines a low-voltage power supply with two mechanical relay outputs. The universal input supports compatible thermocouples, resistance temperature detectors, and analog process signals. A standard faceplate incorporates red and green seven-segment displays for viewing process information and controller settings.

Key Features:

• Limit Monitoring: Responds to configured process boundaries for equipment shutdown or supervisory functions.
• Universal Input: Accepts supported temperature sensors and analog process signals.
• Dual Relay Outputs: Provides mechanical relay outputs in positions one and two.
• Serial Communication: Incorporates EIA-485 Modbus RTU for compatible supervisory connections.
• Low-Voltage Supply: Uses 15–36 volts direct current or 24 volts alternating current.
• Local Display: Presents operating information through red and green seven-segment displays.
• Panel Installation: Uses a 1/16 DIN format with a standard faceplate.

The PM6L3EJ-1AAAAAA delivers the reliability and precision required for limit supervision in compatible industrial temperature and process systems.
