HE693CBL150 | Horner Electric Series 90-30 Compatible I/O Expansion Cable — GE 90-30 Baseplate Connection

HE693 Series — Horner Electric's Series 90-30 Compatible Products

The HE693CBL150 is part of Horner Electric's HE693 product family — a range of PLC modules, accessories, and cables designed to be compatible with the GE Fanuc / Emerson Series 90-30 PLC platform. The "HE693" prefix follows the same product identification convention as the GE Fanuc "IC693" prefix, with "HE" identifying Horner Electric as the manufacturer of this compatible accessory.

Horner Electric (now Horner APG) specialises in industrial automation products including HMIs, controllers, and system accessories — the HE693 cable line provides Series 90-30 compatible expansion cables for integrators and facilities maintaining GE Series 90-30 based automation systems.

Key Product Information

Series 90-30 I/O Expansion — How Expansion Cables Work

In a GE Series 90-30 PLC system, the CPU baseplate can connect to multiple I/O expansion baseplates using a daisy-chain of expansion cables:

CPU baseplate to first expansion baseplate: The first expansion cable connects the CPU baseplate's expansion port (right side) to the first expansion baseplate's bus input (left side).

Wye (Y) configuration: Series 90-30 expansion cables use a Wye connector configuration — one single-headed connector on one end (connects to the CPU baseplate or incoming cable) and a dual-headed (male and female) connector on the other end. The male connector mates with the expansion baseplate; the female connector allows the next cable in the chain to continue the bus.

Termination: The final expansion baseplate or remote baseplate in the chain requires the exposed female connector to remain unconnected, or a terminator to be fitted — leaving the bus unterminated causes signal reflections and communication errors.

Applications

Series 90-30 I/O rack expansion: Manufacturing facilities, process plants, and industrial automation installations using GE Series 90-30 PLCs that require more I/O modules than the CPU baseplate alone accommodates — expansion cables link additional I/O baseplates to the CPU.

Legacy system maintenance: Existing GE Series 90-30 installations where an original expansion cable requires replacement — the HE693CBL150 provides a compatible replacement for maintaining the I/O expansion chain.

System integration projects: Integrators building Series 90-30 based control panels — the HE693 cable provides compatible expansion bus connectivity for systems using both GE IC693 and Horner HE693 components.

FAQ

Q1: Is HE693CBL150 electrically compatible with GE Fanuc IC693CBL series cables?

The HE693 cables are designed as compatible alternatives to GE IC693 series cables — sharing the same 25-pin D-type connector format and Series 90-30 expansion bus electrical specification. The HE693CBL150 is positioned as a compatible replacement for the corresponding IC693CBL cable. For critical installations, verify specific electrical compatibility from Horner Electric's compatibility documentation or the GE/Emerson Series 90-30 installation manual.

Q2: Can HE693CBL150 be mixed with IC693CBL cables in the same Series 90-30 expansion chain?

In practice, HE693 and IC693 cables with the same connector format and bus specifications are often used in combination within the same Series 90-30 I/O chain — the bus electrical specification is the determining factor rather than the cable brand. Verify that the total aggregate cable length remains within the Series 90-30 system limits regardless of cable brand combination.

Q3: What happens if the Series 90-30 expansion bus is left unterminated at the end of the chain?

An unterminated expansion bus end causes signal reflections — the bus electrical signal reflects back along the cable when it reaches the open end, interfering with the forward-traveling data. This manifests as intermittent I/O communication errors, erratic I/O status in the CPU programme, and potentially complete loss of communication with expansion baseplates. Always terminate the Series 90-30 expansion bus at the final baseplate in the chain.

Q4: Is HE693CBL150 compatible with PACSystems RX3i baseplates?

GE's PACSystems RX3i platform uses a different expansion bus interface than the Series 90-30. While some RX3i hardware accepts Series 90-30 I/O modules, the expansion cable interface specification differs between the platforms. Confirm from Horner Electric's compatibility documentation and GE/Emerson's RX3i migration guides whether HE693CBL150 is compatible with the specific RX3i configuration in use.
