Products details
The Honeywell 10024/H/I is an Enhanced Communication Module (ECM) designed for seamless
integration into the FSC (Fail-Safe Control) system, serving dual core communication purposes:
internal communication between redundant FSC Central Parts via the H-interface and external data
exchange with devices supporting RS485/RS422 via the I-interface. As a critical communication hub, it
features a dedicated on-board processor and memory to offload communication tasks from the FSC
central processor, ensuring reliable and efficient data transmission in mission-critical industrial
environments such as oil & gas and chemical processing. It supports multiple communication
protocols (including FSC-FSC, ModBus RTU/H&B, RKE3964R), sequence-of-event recording (SER), and
report generation, adapting to complex industrial control workflows. The module adheres to strict
safety and compliance standards (CE, UL, TÜV) and is compatible with FSC software versions ≥ 2.78f
(configuration software ≥ 530), meeting the requirements of safety-related applications.
Technical data
Hardware & Interface Details
The 10024/H/I has a modular design with a main board (10024/1/1) and two interfaces. The main board has a dedicated processor, 8 Mbit flash memory (supports EPROMs like 27C512), and jumpers (J1/J2 for COM number, J3 for program source, J4/J5 for EPROM type). It occupies 8 TE (8 HP) horizontal and 3 HE (3U) vertical rack space, runs on 5 Vdc (675 mA current, <50 mV p-p ripple), and works in 0°C-60°C, ≤95% RH (non-condensing) environments.
It integrates an H-interface (RS422 with readback) for internal redundant Central Part communication—2 Mbaud baud rate, 1.5 m max cable (Belden 9728/8314), male 9-pin connector, no galvanic isolation, and self-test for fault-triggered Central Part shutdown. The I-interface (isolated RS485/RS422) is for external communication—>6 kV isolation, up to 2 Mbaud (60 m cable), male 9-pin connector, watchdog circuit, max 16 I-interfaces per system.
For integration, it needs a system bus (7-SBUS/12-SBUS/17-SBUS) jumper removed, supports FSC software ≥2.78f, meets EMC standards (EN 50081-2/EN 50082-2), has CE/UL/TÜV approvals (part number 10024/H/I 26900), and must not be hot-swapped.
