1785-TR10BT Ethernet transceiver  

Product Details Introduction

1785-TR10BT Ethernet transceiver (AUI to 10BASE-T)

1785-TR10BT is an AUI to 10BASE-T twisted pair transceiver designed by Rockwell Allen Bradley specifically for the PLC-5 series. It is used to convert the AUI interface of PLC-5 Ethernet modules (such as 1785-ENET) to a standard RJ45 twisted pair network port, achieving 10Mbps industrial Ethernet access.

Core parameters (plain text, no links)

Model: 1785-TR10BT, Series A, AUI to 10BASE-T transceiver.

Protocol standard: Compatible with IEEE 802.3 10BASE-T, 10Mbps half duplex.

Interface:

Device end: AUI interface (15 pin D-sub), directly connected or connected to PLC-5 Ethernet module through AUI cable.

Network end: 8-pin RJ45 socket, connected to shielded/unshielded twisted pair.

Power supply: rated 12V DC (range 10-16V DC), typical current 50mA.

Core functions:

Data transmission and reception, conflict detection and indication.

SQE testing (heartbeat detection) can be externally disabled.

Jabber control (ultra long packet protection, timeout of 20ms).

Link status monitoring, automatic polarity reversal (APX).

Status indication: onboard LED, displaying send/receive, conflict, link, polarity status.

Physical specifications: Size approximately 44 × 22 × 91mm, weight approximately 0.06-0.13kg.

Environmental parameters: working temperature 0-50 ° C, humidity 10% -90%, no condensation.

Product status: discontinued, market mainly focused on refurbishment/spare parts.

Compatibility: Only compatible with PLC-5 series Ethernet modules (1785-ENET), not compatible with new platforms such as ControlLogix.

Application: Ethernet networking, upper computer communication, data acquisition, and program upload and download for old PLC-5 systems.

1785-TR10BT is a specialized accessory for PLC-5 system AUI to twisted pair cables, which solves the compatibility problem of early industrial Ethernet interfaces and ensures the stability of old production line networks.
