The 8021-CE-LH is a left‑hand carrier extender from GE/Emerson‘s PAC8000 series, engineered to physically and electrically bridge separate I/O carrier runs within a distributed control system. The 8021-CE-LH pairs with its right‑hand counterpart, the 8020-CE-RH, to extend both the Railbus communication bus and system power across multiple carriers. With a rugged polycarbonate housing and integral DIN‑rail fixings, the 8021-CE-LH provides a male Railbus connector and a 37‑pin Sub‑D extender cable interface. Supporting up to three extender pairs per node and 32‑/64‑slot addressing, the 8021-CE-LH enables scalable, high‑density I/O architectures for demanding industrial automation environments
Industrial Process Control – Expanding I/O capacity in large‑scale distributed control systems (DCS)
Hazardous Area Installations – Suitable for Class I Division 2 and Zone 2 classified locations
Modular System Configurations – Facilitating the addition of carriers in complex automation setups
Retrofit & Upgrade Projects – Enabling scalable system growth without replacing existing PAC8000 infrastructure
Remote I/O Networks – Extending Railbus communication and power across physically separated I/O racks
Railbus & Power Continuity – Ensures seamless Railbus communication and power supply continuity between separate carrier runs
Left‑Hand Configuration – Designed as the left‑hand side of a carrier extender pair; pairs with right‑hand counterpart 8020‑CE‑RH
Male Railbus Connector – Provides a male‑out Railbus carrier connector for interconnection
37‑Pin Sub‑D Extender Cable Interface – Standardized connector for reliable multi‑way cable linking
6‑Terminal System Power Block – Screw terminals for HVCC+, HVCC‑, and SGND connections
Integral DIN‑Rail Mounting – Compatible with Top hat (EN 50022) and G‑section (EN 50035) rails
Hazardous Area Certified – Approved for Class I Division 2 / Zone 2 installations
Compact Form Factor – 42 mm width saves valuable cabinet space
True ‘Plug‑and‑Play’ Expansion – Unlike passive connectors, the 8021-CE-LH actively maintains Railbus signal integrity and power distribution across extended distances, enabling transparent system growth without complex reconfiguration.
Scalable Distributed Architecture – Supports up to three extender pairs per node and both 32‑slot and 64‑slot addressing, making it suitable for large‑scale PAC8000 installations with thousands of I/O points.
Rugged Industrial Design – Withstands extreme temperatures (–40°C to +70°C) and vibration, making it suitable for harsh environments such as oil refineries and chemical plants.
Global Hazardous Area Approvals – Certified for Class I Division 2 / Zone 2, simplifying deployment in explosive atmospheres worldwide.
Cost‑Effective System Growth – Enables adding remote I/O drops without replacing existing controller infrastructure, significantly reducing hardware, wiring, and commissioning costs
Q1: What is the primary function of the 8021-CE-LH?
A1: The 8021-CE-LH is a left‑hand carrier extender for the PAC8000 I/O system. It extends the Railbus communication bus and system power across separate I/O carrier runs, enabling scalable, distributed control architectures.
Q2: What is the difference between the 8021-CE-LH and the 8020-CE-RH?
A2: The 8021-CE-LH is the left‑hand carrier extender with a male‑out Railbus connector, while the 8020-CE-RH is the right‑hand counterpart with a female‑in Railbus connector. They are used together as a pair to link separate carrier runs.
Q3: How many extender pairs can be used per PAC8000 node?
A3: A single PAC8000 node supports a maximum of three extender pairs (three 8021-CE-LH + three 8020-CE-RH).
Q4: Is the 8021-CE-LH suitable for hazardous area installations?
A4: Yes. The 8021-CE-LH is certified for Class I Division 2 / Zone 2 hazardous locations with T4 temperature classification.
Q5: What addressing capabilities does the 8021-CE-LH support?
A5: The 8021-CE-LH supports both 32‑slot and 64‑slot addressing, providing flexibility for different system configurations and I/O density requirements.
