Honeywell TC-PGCN11 Intrinsically Safe ControlNet Gateway

Honeywell TC-PGCN11 Intrinsically Safe ControlNet Gateway

Product Introduction

The Honeywell TC-PGCN11 acts as a communication gateway for hazardous area applications. It connects up to eight I/O modules to a ControlNet network. Moreover, this module provides intrinsically safe power to field devices. You can use it in environments requiring explosion protection.

Additionally, the TC-PGCN11 features full galvanic isolation. It separates the backplane bus, power supply, and ControlNet ports. This design prevents dangerous energy from reaching the field. The module also meets stringent European standards for intrinsic safety.

Certifications and Standards

The TC-PGCN11 holds multiple important certifications.

Standards Compliance

• DIN EN 50014: 1992

• DIN EN 50020: 1994

• Climatic conditions per DIN IEC 721

• EMC compatibility per DIN EN 50081-2, DIN EN 50082-2, NAMUR NE 21

CE Conformity (Europe)
To achieve EMC protection class, you must mount this module in a cabinet with a copper seal. Additionally, install ferrites on the power supply and ControlNet coaxial cables.

CENELEC Classification (Europe)

• II 2 G EEx ib IIC/IIB, T4

This classification confirms the Honeywell TC-PGCN11 is intrinsically safe for gas groups IIC and IIB. The T4 temperature rating allows use in environments with auto-ignition temperatures above 135°C.

Installation Guidelines

Follow these steps to install the TC-PGCN11 correctly.

First, mount the module in an IP54 or better enclosure. The module itself is only IP20 rated. Next, connect the 24V dc power supply using 12 AWG stranded wire. Strip the insulation to 1.2mm maximum.

Then, attach the ControlNet cable (Belden 3092A) to the external bus ports. Meanwhile, verify the ferrites are installed on both power and coax cables for CE compliance. For hazardous area installation, ensure all intrinsically safe wiring remains separated from non-IS circuits.

Finally, power up the system. The TC-PGCN11 will automatically communicate with the connected I/O modules. Check the status indicators to confirm normal operation.

Frequently Asked Questions (FAQ)

1. How many I/O modules can the TC-PGCN11 support?
It supports up to eight I/O modules. These modules connect through the vendor-specific backplane bus.

2. What type of ControlNet cable is required?
You must use Belden 3092A cable. Refer to Honeywell's Experion Controller Specification for complete details.

3. Is the Honeywell TC-PGCN11 suitable for Zone 2 hazardous areas?
Yes. It carries CENELEC certification II 2 G EEx ib IIC/IIB T4. This allows installation in Zone 1 and Zone 2 areas.

4. Why do I need an IP54 enclosure for field installation?
The module has IP20 protection only. An IP54 enclosure protects against dust and water splashes in field locations.

5. Which shipping carriers do you use?
We ship using Fedex, UPS, and DHL. Tracking details are provided after dispatch.
