General Information

Core Description

The GJR2368900R1313 is a high-performance ABB PROCONTROL P serial interface coupling module featuring dual RS232c and RS422 protocol processing. Fully compatible with standard station-bus subracks, this 87TS01K-E unit works seamlessly with industrial computers, diagnostic stations, and operator terminals to deliver flexible data routing and stable distributed network communication.

Competitive Advantage

• Dual Serial Interface Protocol Integration: Hosts both RS232c and RS422 interface chipsets wired in parallel on two front-facing 25-pole connectors, accommodating both direct long-distance loops and local computing node attachments without stacking separate expansion boards.
• Automatic Intelligent Interface Changeover: Integrates a specialized hardware sense circuit on the front connector ENABLE lines that automates the transition from RS422 to RS232c configuration metrics when grounding is introduced, entirely dropping manual jumper changes.
• Multi-Module Parallel Bus Interconnection: Supports multidrop RS422 array architecture allowing up to five separate 87TS01 serial modules to bridge in a synchronized layout and hook together to a single computing platform to save physical terminal real estate.

System Compatibility & Alternatives

• System Compatibility: The module connects to any standard PROCONTROL bus station slot equipped with address wiring 1 through 58, requiring a redundant 24V module power supply configuration. The station-bus interface utilizes dedicated shared memories supporting up to 230 concurrent receive telegrams and 200 send-location telegrams.
• Alternative Model: 87TS01-E/R1210 (GJR2368900R1210)
• Difference from Alternative: The GJR2368900R1313 (R13xx revision) utilizes an expanded 32 K x 8 bits shared RAM memory framework at position A105 compared to the smaller 8 K x 8 bits basic shared memory structure built into the legacy R12xx series hardware card. This higher capacity accommodates larger block telemetry configurations and faster communication processing across modern distributed network infrastructures.

Installation & Troubleshooting FAQ

Q1: What are the factory default data rates and how can the baud rates be reconfigured?

A: Both integrated channels are configured from the factory to operate at 9600 baud. Technicians can change the operational rates independently from 300 up to 19200 baud by altering wire-wrap pin layouts at jumper track X7 and placing plug-in jumper elements at tracks X15 and X16.

Q2: How do I force the module to select an active RS232c line path over the standard RS422 mode?

A: In the absence of an active grounding circuit, the module defaults to standard RS422 layout across both D-sub connectors. To change over to the active RS232c interface layer, apply a low-impedance BUSEN connection signal relative to local GND at terminal pin 13 of the mating cable plug assembly.

Q3: What do the front-facing red diagnostic LEDs signify during a link failure?

A: Red LED indicators isolate structural subsystem failure points: ST illuminates if an active error or transmission failure is captured within the local station-bus link hardware, while STV signals a logic processing crash inside the computing section.

Q4: How should a parallel multi-card RS422 configuration be terminated to preserve signal line balance?

A: When interconnecting multiple modules in parallel via 89IP03 links, you must secure an 89IP04 resistor array onto the remaining unlinked front interface socket of the final active card in the layout. This sets the proper 100-ohm balanced differential impedance profile across the wire runs.

Q5: What are the physical space allocations and energy dissipation thresholds required inside the panel?

A: This module features standard eurocard sizing, but requires exactly 2 divisions of physical slide space inside the subrack rail. The typical continuous power dissipation is rated at 8.2 Watts, meaning you must preserve convective clearance patterns to keep active cards inside the 0 to 70°C operating window.
